10/100/1000Base-T Twisted Pair Ports  
The switches have 24 10/100/1000Base-T ports.  
Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set  
manually using the management software or automatically with Auto-  
Negotiation (IEEE 802.3u), the default setting.  
Note  
The ports must be set to Auto-Negotiation to function at 1000 Mbps  
and are not compatible with devices that are not IEEE 802.3u  
compliant.  
Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The  
duplex mode of a port, like port speed, may be set manually using the  
management software or automatically with Auto-Negotiation (IEEE  
802.3u), the default setting.  
The speed and duplex mode settings of a port may be set independently  
of each other. For example, a port may be configured such that its speed  
is set manually while its duplex mode is established through Auto-  
Negotiation.  
Note  
A switch port should not use Auto-Negotiation to set its duplex mode  
if it is connected to a network device that does not support Auto-  
Negotiation for 10 or 100 Mbps operation and has a fixed duplex  
mode of full-duplex. Otherwise, a duplex-mode mismatch may occur  
in which a switch port and a network device operate at different  
duplex modes. The duplex modes of switch ports that are connected  
to network devices that do not support Auto-Negotiation should be  
set manually through the management software.  
Wiring The wiring configuration of a port operating at 10 or 100 Mbps can be MDI  
or MDI-X. The wiring configurations of a switch port and a network device

connected with straight-through twisted pair cabling have to be opposite,  
such that one device is using MDI and the other MDI-X. For instance, a  
switch port has to be set to MDI-X if it is connected to a network device set  
to MDI.  
You may set the wiring configurations of the ports manually or let the  
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab-  
compliant). This feature enables the switch to automatically negotiate with  
network devices to establish their proper settings.

IX5-28GPX Installation Guide  
Power Over Ethernet  
The AT-IX5-28GPX switch features Power over Ethernet (PoE) on the 10/  
100/1000Base-T ports. PoE is used to supply power to network devices  
over the same twisted pair cables that carry the network traffic.  
The main advantage of PoE is that it can make it easier to install a  
network. The selection of a location for a network device is often limited by  
whether there is a power source nearby. This often limits equipment  
placement or requires the added time and cost of having additional  
electrical sources installed. But with PoE, you can install PoE-compatible  
devices wherever they are needed without having to worry about whether  
there are power sources nearby.  
A device that provides PoE to other network devices is referred to as  
power sourcing equipment (PSE). The AT-IX5-28GPX switch acts as a  
PSE unit by adding DC power to the network cable, thus functioning as a  
central power source for other network devices.  
Devices that receive their power from a PSE are called powered devices  
(PD). Examples include wireless access points, IP telephones, webcams,  
and even other Ethernet switches.  
The switch automatically determines whether or not a device connected to  
a port is a powered device. Ports that are connected to network nodes that  
are not powered devices (that is, devices that receive their power from  
another power source) function as regular Ethernet ports, without PoE.  
The PoE feature remains activated on the ports but no power is delivered  
to the devices.  
PoE Standards The AT-IX5-28GPX switch supports these PoE standards:  
ˆ PoE (IEEE 802.3af): This standard provides up to 15.4 watts at the  
switch port to support powered devices that require up to 12.95 watts.  
ˆ PoE+ (IEEE 802.3at): This standard provides up to 30.0 watts at the  
switch port to support powered devices that require up to 25.5 watts.

Power Budget The AT-IX5-28GPX switch has a power budget of 720 watts when two  
power supply modules are installed. This is the maximum amount of power  
the switch can provide at one time to the powered devices.  
Two power supplies must be installed for the switch to provide the full 720  
watts. Each power supply is responsible for providing 360 watts, or half, of  
the power budget. The power budget is reduced to 360 watts if only one  
power supply is installed.  
The power requirements of the PoE devices determine the maximum  
number of devices the switch can support at one time. So long as the total  
power requirements of the powered devices is less than the power budget  
of the switch, the switch can supply power to all the devices. But if the total  
power requirements exceed the power budget, the switch denies power to  
one or more ports using a mechanism referred to as port prioritization.  
To determine whether the power requirements of the PoE devices you  
plan to connect to the switch exceed its power budget, refer to their  
25

Chapter 1: Overview  
documentation for their power requirements and add the requirements  
together. The switch should be able to power all of the devices  
simultaneously as long as the total is below its power budget. If the total  
exceeds the available power budget, you should consider reducing the  
number of PoE devices so that all of the devices receive power.  
Otherwise, the switch powers a subset of the devices, based on port  
prioritization.  
The switch can handle different power requirements on different ports.  
This enables you to connect different classes of PoE equipment to the  
ports on the switch.  
Port If the power requirements of the powered devices exceed the switch’s  
power budget, the switch denies power to some ports based on a system  
Prioritization  
called port prioritization. You may use this mechanism to ensure that  
powered devices critical to the operations of your network are given  
preferential treatment by the switch in the distribution of power should the  
demands of the devices exceed the available capacity.  
There are three priority levels:  
ˆ Critical  
ˆ High  
ˆ Low  
Ports set to the Critical level, the highest priority level, are guaranteed  
power before any of the ports assigned to the other two priority levels.  
Ports assigned to the other priority levels receive power only if all the  
Critical ports are receiving power. Ports that are connected to your most  
critical powered devices should be assigned to this level. If there is not  
enough power to support all the ports set to the Critical priority level,  
power is provided to the ports based on port number, in ascending order.  
The High level is the second highest level. Ports set to this level receive  
power only if all the ports set to the Critical level are already receiving  
power. If there is not enough power to support all of the ports set to the  
High priority level, power is provided to the ports based on port number, in  
ascending order.  
The lowest priority level is Low. This is the default setting. Ports set to this  
level only receive power if all of the ports assigned to the other two levels  
are already receiving power. As with the other levels, if there is not enough  
power to support all of the ports set to the Low priority level, power is  
provided to the ports based on port number, in ascending order.  
Power allocation is dynamic. Ports supplying power to powered devices  
may cease power transmission if the switch’s power budget is at  
maximum usage and new powered devices, connected to ports with  
higher priorities, become active.

IX5-28GPX Installation Guide  
You can use port prioritization on dual power supply PoE switches to  
protect your important networking devices from loss of power should one  
of the power supplies fail or lose power. If you limit the power requirements  
of the critical devices connected to a switch to less than 360 watts, the  
PoE power provided by a single power supply module, a switch will have  
sufficient power to support the critical devices even if it has only one  
functional power supply module.  
Wiring The IEEE 802.3af standard defines two methods for the delivery of DC  
power over twisted pair cable by a PSE, such as the switch, to PDs. These  
methods, known as modes A and B, identify the wires within the cable that  
carry the DC power from the PSE to a PD.  
Implementation  
Twisted pair cabling typically consists of eight wires. With 10Base-T and  
100Base-TX devices, the wires connected to pins 1, 2, 3, and 6 on the RJ-  
45 connectors carry the network traffic while the wires connected to pins 4,  
5, 7, and 8 are unused. With 1000Base-T devices, all eight wires are used  
to carry network data.  
It takes four wires to deliver DC power to a PD. With Mode A, the power is  
delivered on pins 1, 2, 3, and 6. These are the same pins in 10Base-T and  
100Base-TX devices that carry the network data. With mode B, the power  
is provided over the spare wires.  
The ports on the AT-IX5-28GPX switch deliver the power using pins 1, 2,  
3, and 6, which corresponds to mode A in the IEEE 802.3af standard.  
Powered devices that comply with the IEEE 802.3af standard are required  
to support both power delivery methods. Legacy devices that do not  
comply with the standard will work with the switch if they are powered on  
pins 1, 2, 3, and 6.

Chapter 1: Overview  
SFP+ Slots  
The switches have four SFP+ slots that support the following types of SFP  
1000Mbps and SFP+ 10Gbps transceivers:  
ˆ 1000Base-SX/LX SFP transceivers  
ˆ Single-port BiDi 1000Base-LX SFP transceivers  
ˆ 1000Base-ZX SFP transceivers  
ˆ 10Gbps, 10GBase-SR/LR fiber optic transceivers  
ˆ 10Gbps AT-SP10TW direct connect twinax cables with SFP+  
transceiver-style connectors  
You may use the transceivers to connect switches to other network  
devices over large distances, build high-speed backbone networks  
between network devices, or connect high-speed devices, such as  
servers, to your network.  
The switches support a variety of short and long distance SFP and SFP+  
modules. For a list of supported SFP modules, contact your Allied Telesis  
representative or visit our web site.  
Note  
SFP+ slots 27 and 28 are initially configured as stacking slots for the  
VCStack feature. If you intend to use the switch as a stand-alone  
unit, you must disable the VCStack feature before using the slots  
with standard SFP or SFP+ transceivers. See Chapter 5,  
“Configuring the Switch for Stand-alone Operations” on page 77 for  
instructions.

IX5-28GPX Installation Guide  
Stacking SFP+ Slots  
Two of the four SFP+ slots on the front panel of the switch can be used  
with stacking transceivers to create a VCStack of up to four AT-IX5-  
28GPX switches. The switches of a VCStack act as a single virtual unit.  
They synchronize their actions so that switching operations, like spanning  
tree protocols, virtual LANs, and static port trunks, span across all the  
units and ports. The two main advantages of stacks are:  
ˆ You can manage multiple units simultaneously, which can simplify  
network management.  
ˆ You have more flexibility in how you configure some of the  
features. For instance, a static port trunk on a stand-alone switch  
has to consist of ports from the same switch. In contrast, a static  
trunk on a stack may consist of ports from different switches in the  
same stack.  
The slots for the stacking transceivers are SFP+ slots 27 and 28.  
Note  
If you use the switch as a stand-alone device, you can use the slots  
with regular SFP and SFP+ transceivers by disabling the VCStack  
feature. See Chapter 5, “Configuring the Switch for Stand-alone  
Operations” on page 77 for instructions.

eco-friendly Button  
You may turn off the port LEDs to conserve electricity when you are not  
monitoring the switch. The LEDs are toggled with the eco-friendly button  
on the front panel of the switch or the ECOFRIENDLY LED and NO  
ECOFRIENDLY LED commands in the Global Configuration mode of the  
command line interface. The switch is said to be operating in a low power  
mode when the LEDs are turned off.  
Operating the switch in the low power mode with the LEDs turned off does  
not interfere with the network operations of the device.  
The Switch ID LED is always on, but it displays different information  
depending on whether the LEDs are on or off. When the LEDs are on, the  
ID LED displays the switches ID number. When the switch is operating in  
the low power mode with the LEDs off, the LED indicates whether the  
switch is a stand-alone unit or the master or member switch of a VCStack,  
as detailed in Figure 8 on page 35.  
Note  
Before checking or troubleshooting the network connections to the  
ports on the switch, you should always check to be sure that the  
LEDs are on by either pressing the eco-friendly button or issuing the  
ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in  
the command line interface.

Console Port  
The Console port is used to establish a management session with the  
switch to configure its features and parameter settings. This type of  
management uses serial RS-232 and is commonly referred to as local or  
out-of-band management because it is not conducted over your network.  
To perform local management, you must be at the location of the switch  
and must use the management cable included with the switch.  
To establish a local management session with the switch, connect a  
terminal or a personal computer with a terminal emulation program to the  
Console port, which has an RJ-45 style (8P8C) connector, using the  
provided management cable. The cable has RJ-45 RJ-style (8P8C) and  
DB-9 (D-sub 9-pin) connectors.

Power Supplies  
The AT-IX5-28GPX switch has two rear slots for hot-swappable power  
supplies.  
The switch is supplied with a factory installed blank panel that covers both  
power supply slots, and with a separate blank panel to use if you only  
install one power supply.  
One or two AT-PWR800 (800W) power supplies can be installed in these  
switches. These power supplies are illustrated in Figure 9 on page 38.  
Installing two power supplies provides a switch with power redundancy  
and protect against interruptions to network operations in the event one of  
the power supplies loses power or fails.  
The switch has a PoE budget of 720 watts when both power supplies are  
active and 370 watts when only one power supply is active. For further  
information, refer to “Power Budget” on page 27.

Chapter 2: Virtual Chassis Stacking  
Overview  
Virtual Chassis Stacking (VCStack) allows you to connect up to four AT-  
IX5-28GPX switches to form a virtual switch in which the devices function  
as a single networking unit. The benefits of VCStack are:  
ˆ Simplifies management - You can manage the devices of the stack  
as a single unit, rather than individually. Your local and remote  
management sessions automatically give you management  
access to all the devices.  
ˆ Reduces IP addresses - A stack requires only one IP address for  
remote management access, thereby reducing the number of IP  
addresses you have to assign to network devices, The one  
address gives you management access to all the units.  
ˆ Adds feature flexibility and resiliency - A stack gives you more  
flexibility in how you can configure some features. For instance,  
you can create port aggregators of ports from different switches in  
the stack, rather than from only one switch. If you distribute the  
ports of an aggregator across two or more switches in a stack, you  
increase its resiliency because the aggregator will continue to  
function, though at a reduced bandwidth, if one of the switches  
stops functioning.  
ˆ Reduces protocol requirements - Creating a stack might eliminate  
your need to configure some protocols, such as the Virtual Router  
Redundancy Protocol and Spanning Tree Protocol.

Stacking Slots  
The AT-IX5-28GPX switches come with two stacking slots. The slots are  
the last two SFP+ slots on the switches and are labeled S1/27 and S2/28.  
The slots have two functions. You may use them with the VCStack feature  
to build a stack of switches or, by disabling the VCStack feature, you may  
use them with regular SFP or SFP+ transceivers as additional networking  
slots.  
The names of the slots depend on the status of the VCStack feature on the  
switch. The management software refers to the slots as “S1” and “S2.”  
when the VCStack feature is enabled and the slots are used with the  
special stacking transceivers to create a stack.  
When you disable the VCStack feature to use the slots with regular SFP or  
SFP+ transceivers on a stand-alone switch, the slots are referred to as  
slots 27 and 28. See Chapter 5, “Configuring the Switch for Stand-alone  
Operations” on page 57 for instructions for disabling VCStack.  
Note  
When VCStack is enabled on the switch, the stacking slots only  
work with the stacking transceivers in Table 7 on page 42. If you  
install regular SFP or SFP+ transceivers in the stacking slots when  
stacking is activated, the management software disables them and  
enters an error message in the buffered log.

IX5-28GPX Installation Guide  
Here are the transceiver guidelines:  
ˆ The stacking transceivers may only be used in the stacking slots  
and only with the VCStack feature. You may not use the  
transceivers as regular networking ports.  
ˆ The AT-StackOP/0.3 and AT-StackOP/9.0 transceivers must be  
connected to other AT-StackOP/0.3 and AT-StackOP/9.0  
transceivers. The transceivers do not work with other types of  
network devices.  
ˆ You may use different types of transceivers to connect the  
switches of a stack and so build stacks of switches that are at  
various distances from each other.

Chapter 2: Virtual Chassis Stacking  
Stacking Port Topologies  
The switches of a stack are connected with the S1 and S2 ports and the  
stacking transceivers shown in Figure 10 on page 42.  
There are two wiring configurations. The first topology is called the linear  
topology. In this topology the switches are connected with a single  
pathway. A stacking transceiver in one switch is connected to a stacking  
transceiver in the next switch, which is connected to the next switch, and  
so on. The connections must crossover to different stacking slots on the  
switches. The stacking transceiver in the S1 slot in one switch must  
connect to the stacking transceiver in the S2 slot in the next switch.  
Figure 11 is an example of a stack of two switches in the linear topology.  
The transceiver in the S1 slot on the top switch is connected to the  
transceiver in the S2 slot on the bottom switch.

Figure 12. Stack of Four Switches in the Linear Topology  
The second topology is called the ring topology. It is similar to the linear  
topology, except that the unused stacking ports on the end switches of the  
stack are connected to form a physical loop. This topology is more resilient  
than the linear topology because there are two pathways through the  
stack. If one pathway fails, the switches can maintain communications  
through the alternate pathway. The example in Figure 13 on page 46  
shows a ring topology of two switches.

Figure 14. Stack of Four Switches in the Ring Topology  
The topologies are the same in terms of network speed and performance.  
However, the ring topology is the recommended wiring configuration  
because of the secondary path through the stacking ports. The two  
pathways protect the switches of the stack against the loss of  
communications due to a failure of a stacking port, cable, or switch.  
The examples in the previous figures showed the twinax AT-StackXS/1.0  
stacking transceiver. But the same rules apply to the fiber optic AT-  
StackOP/0.3 and AT-StackOP/9.0 stacking transceivers. A fiber optic  
transceiver in the S1 slot must crossover to a fiber optic transceiver in the  
S2 slot of another switch.

Chapter 2: Virtual Chassis Stacking  
Master and Member Switches  
The stack has one master switch. The functions of the master switch  
include:  
ˆ Coordinating and monitoring stack operations.  
ˆ Verifying that the switches are using the same version of  
management software. It automatically downloads its management  
software over the stacking cables to switches with different  
software versions.  
ˆ Verifying that the switches have different ID numbers. It  
automatically assigns new ID numbers to resolve situations where  
two or more switches have the same ID number.  
ˆ Verifying that the stacking transceivers that connect the switches  
together are cabled correctly.  
The other switches are called member switches. There can be up to three  
member switches in addition to the master switch. A member switch can  
automatically transition to the master role if the current master switch is  
removed from the stack or powered off. This ensures continued operations  
of the stack even if the master switch stops operating.  
Selection of the The devices compare the following numbers to choose the master switch  
when the stack is reset or powered on:  
Master Switch  
ˆ Stack priority numbers  
ˆ MAC addresses  
The stack priority number is an adjustable value of 0 to 255, where the  
lower the number, the higher the priority. Typically, the switch with the  
lowest priority number (highest priority) becomes the master switch of a  
stack. The default priority value is 128.  
If the switches have the same priority values, the selection of the master  
switch is based on their MAC addresses. As with the priority value, the  
lower the MAC address, the higher the priority. The switch with the lowest  
MAC address becomes the master switch.  
If you power on the stack for the first time without adjusting the priority  
values, the master switch is selected based on the MAC addresses if the  
units are powered on simultaneously. If you power on the switches one at  
a time, the master switch is the first switch to be powered on. This is  
explained in Chapter 8, “Powering On the Stack” on page 101.  
After the stack is established and operating, you may, if you choose,  
change the priority settings on the individual units and so control which  
switch will be the master switch after subsequent power cycles and resets.

IX5-28GPX Installation Guide  
ID Numbers Each switch must be assigned an ID number. The range is 1 to 4 and the  
default is 1. The ID numbers are displayed on the ID LEDs on the front  
panels of the units. You may assign the numbers yourself or you can let  
the master switch assign the numbers automatically, as explained in  
Chapter 8, “Powering On the Stack” on page 101.  
You use the ID numbers to identify the individual ports and switches when  
you configure the devices with the commands in the management  
software. For further information, refer to “Specifying Ports in the  
Command Line Interface” on page 50.  
The ID numbers are also used to identify the parameter settings that are  
stored in the configuration file. When the stack is reset or power cycled,  
the ID numbers identify the devices to which the parameter settings  
belong.  
Caution  
You should not change the ID numbers of the switches after you  
have started to configure the parameter settings. Otherwise, the  
parameter settings might be applied to the wrong devices when you  
reset or power cycle the stack.  
The switches do not use the ID numbers to select the master switch. The  
selection of the master switch is typically based on the priority numbers  
and MAC addresses, as previously explained.

Chapter 2: Virtual Chassis Stacking  
Specifying Ports in the Command Line Interface  
The command line interface in the management software on the switch  
has a parameter that you use to specify the individual ports. The  
parameter is the PORT parameter and Figure 15 shows its format.  
port1.0.n  
Stack ID  
Module ID  
Port Number  
Figure 15. PORT Parameter in the Command Line Interface  
The first number is the switch’s ID number. The ID numbers of switches in  
a stack are displayed on their ID LEDs. You can also view the ID numbers  
with the SHOW STACK command in the command line interface.  
The module ID value is used with multi-module products. This value does  
not apply to the x510 Series switches and should always be 0.  
The third value is a port number on the switch. You may specify only one  
port number in a PORT parameter, but you may specify more than one  
PORT parameter in many of the commands where the parameter is  
supported.  
Here is an example of the PORT parameter. It uses the INTERFACE  
command to enter the Port Interface mode for ports 15 and 17 on the  
switch with ID 2:  
awplus> enable  
awplus# configure terminal  
awplus(config)# interface port2.0.15,port2.0.17  
For instructions on the command line interface and the PORT parameter,  
refer to the Software Reference: AlliedWare Plus Operating System for  
IX5-28GPX Switches.

Chapter 3: Beginning the Installation  
Choosing a Site for the Switches  
Observe these requirements when planning the installation of the switches  
of a stack.  
ˆ If you plan to install the switches in an equipment rack, check to be  
sure that the rack is safely secured so that it will not tip over.  
Devices in a rack should be installed starting at the bottom, with  
the heavier devices near the bottom of the rack.  
ˆ If you plan to install the switches on a table, check to be sure that  
the table is level and stable.  
ˆ The power outlet should be located near the switches and be  
easily accessible.  
ˆ The site should allow for easy access to the ports on the front of  
the switches, so that you can easily connect and disconnect  
cables, and view the port LEDs.  
ˆ The site should allow for adequate air flow around the units and  
through the cooling vents on the front and rear panels. (The  
ventilation direction is from front to back, with the fan on the back  
panel drawing the air out of the unit.)  
ˆ The site should not expose the switches to moisture or water.  
ˆ The site should be a dust-free environment.  
ˆ The site should include dedicated power circuits or power  
conditioners to supply reliable electrical power to the network  
devices.  
ˆ Do not install the switches in a wiring or utility box because they  
will overheat and fail from inadequate airflow.  
Warning  
Switches should not be stacked on top of one another on a table or  
desktop because that could present a personal safety hazard if you  
need to move or replace switches.

x510 Series Installation Guide for Virtual Chassis Stacking  
Planning a Stack  
Here are the guidelines to planning a stack:  
ˆ A stack can have up to four AT-IX5-28GPX switches.  
ˆ Any of the switches in the stack can be the master switch.  
ˆ Switches connected with AT-StackXS/1.0 stacking cables should  
be installed in a standard 19-inch equipment rack and not more  
than one meter apart, the length of the stacking cable. The end  
switches cannot be more than one meter apart if you want to  
create the ring topology, shown in Figure 13 on page 46 and Figure  
14 on page 47.  
ˆ You may use the AT-StackOP/0.3 and AT-StackOP/9.0  
transceivers to build stacks of switches that are up to 300 meters  
and 9 kilometers apart, respectively.  
ˆ The wiring topology of the stack may be either linear or ring. Both  
topologies offer the same in terms of speed, but the ring topology  
adds wiring redundancy.  
ˆ You can use combinations of AT-StackXS/1.0, AT-StackOP/0.3,  
and AT-StackOP/9.0 cables when the individual switches of the  
stack are at various distances from each other.  
ˆ The switches do not need any additional software for stacking.  
However, they do need stacking transceivers.  
ˆ You may not install a networking device, such as a media  
converter or Ethernet switch, between two fiber optic stacking  
transceivers.  
ˆ All switches must have the same licenses of optional features. If  
you install an optional feature on one switch, you must install it on  
all switches before assembling the stack.  
ˆ The AT-StackOP/9.0 transceiver has a maximum operating  
distance of 9 kilometers and requires 9/125 µm single-mode fiber  
optic cable. The operating specifications of the transceiver are  
listed in Table 17 on page 129.  
ˆ Table 8 on page 58 lists the maximum distances of the AT-  
StackOP/0.3 transceiver. The operating specifications of the  
transceiver are listed in Table 16 on page 128.

Warning  
Do not stack switches on top of one another on a table or desktop  
because that could present a personal safety hazard if you need to  
move or replace switches.  
After placing the switches on the table or desktop, if you are installing a  
VCStack, go to Chapter 6, “Verifying the Status of VCStack and Activating  
VCStack” on page 85 to verify that VCStack is activated on the units.

Configuring the Switch for Stand-alone Operations  
Disabling After the switch has initialized its management software, examine the  
switch ID LED on the front panel and do one of the following:  
VCStack  
ˆ If the LED is displaying “0,” the installation procedure is complete.  
The switch is now ready for network operations as a stand-alone  
unit. Refer to the Software Reference: AlliedWare Plus Operating  
System for IX5-28GPX Switches for instructions on how to  
configure the operating parameters.  
ˆ If the LED is displaying a number other than “0,” perform the  
following procedures to disable the VCStack feature.  
Caution  
You have to reset the switch as part of the procedure to disabling  
the VCStack feature. Some network traffic may be lost if the device  
is already connected to a live network.  
Note  
The initial management session of the switch must be from the  
Console port.  
To disable the VCStack feature to use the switch as a stand-alone unit,  
perform the following procedure:  
Caution  
Disabling the VCStack feature requires resetting the switch. If the  
switch is already connected to a live network, some network traffic  
may be lost.  
1. Unless you have already done so, start a local management session  
as described in “Starting a Local Management Session” on page 72.  
2. When prompted, enter a user name and password to log on the  
switch. If this is the initial management session of the switch, enter  
“manager” as the user name and “friend” as the password. The user  
name and password are case sensitive.  
The local management session starts when the User Exec mode  
prompt, shown in Figure 34. is displayed.

4. Review the following items:  
ˆ If the Operational Status is “Stacking Hardware Disabled,” the  
VCStack feature is already disabled on the switch and the SFP+  
stacking slots may be used with regular SFP or SFP+ transceivers.  
ˆ If the Operational Status is “Standalone Unit,” as shown in Figure  
35 on page 79, the VCStack feature is active on the unit. You must  
disable it by performing the steps in the rest of this procedure  
before you can use the SFP+ stacking slots with regular SFP or  
SFP+ transceivers. The reason the status says “standalone” is  
because the switch considers itself a stack of one switch.  
5. Move to the Global Configuration mode by entering the ENABLE and  
CONFIGURE TERMINAL commands, as shown in Figure 36.

Confirming the Another way to confirm that VCStack is disabled on the switch is by  
displaying the status of the last two SFP+ slots on the switch. These are  
slots 27 and 28. If VCStack is disabled, you should be able to display the  
status of the slots even when they do not have transceivers. If VCStack is  
not disabled, the switch displays a message that it cannot find the slots. To  
view the status of the stacking slots, perform this procedure:  
Status of the  
VCStack Feature  
1. Start a management session on the switch. For directions, refer to  
“Configuring the Switch for Stand-alone Operations” on page 78.  
2. Log on to the switch. The default user name is “manager” and the  
password is “friend”.  
3. From either the User Exec mode or Privileged Exec mode, enter the  
SHOW INTERFACE command to display the status of one of the last  
two SFP+ slots on the switch. For example, enter this command to  
view the status of slot 27:

Specifying Ports in the Command Line Interface for Stand-alone  
Switches  
The command line interface in the management software on the switch  
has a parameter that you use to specify the individual ports. The  
parameter is the PORT parameter and Figure 42 shows its format.  
port1.0.n  
Stack ID  
Module ID  
Port Number  
Figure 42. PORT Parameter in the Command Line Interface  
The first number is the switch’s ID number. The ID number for stand-alone  
switches is not the value 0 displayed on the Switch ID LEDs. Rather, it is 1.  
Be sure to enter 1, not 0, as the ID number in the PORT parameter when  
configuring ports on stand-alone switches.  
The module ID value is used with multi-module products. This value does  
not apply to the x510 Series switches and should always be 0.  
The third value is a port number on the switch. You may specify only one  
port number in a PORT parameter, but you may specify more than one  
PORT parameter in many commands where the parameter is supported.  
Here is an example of the PORT parameter on a stand-alone switch. It  
uses the INTERFACE command to enter the Port Interface mode for ports  
15 and 17:  
awplus> enable  
awplus# configure terminal  
awplus(config)# interface port1.0.15,port1.0.17  
For instructions on the command line interface and the PORT parameter,  
refer to the Software Reference: AlliedWare Plus Operating System for  
IX5-28GPX Switches.

Chapter 6: Verifying the Status of VCStack and Activating VCStack  
Verifying the Status of VCStack  
Before you install the stacking transceivers to build the stack, you should  
first test the switches to determine whether the VCStack feature is  
enabled or disabled, and enable it on any units where it is disabled. On  
new switches, the feature should be activated because that is the default  
setting. But on switches that were previously used as stand-alone units,  
the feature is probably disabled and needs to be enabled.  
Testing the status of VCStack is simple. You power on a switch and watch  
the ID LED. If it displays a number from 1 to 4, VCStack is already  
enabled. If the LED displays the number 0, the feature is disabled and  
needs to be enabled.  
To test the status of VCStack, perform the following procedure:  
1. Power on one of the switches.  
Connect a power cord to one of the power connectors on the back  
panel and to an AC power source. The unit has two power connectors,  
but you do not need to connect both power cords for this procedure.  
2. Wait one minute for the switch to initialize its management software.  
3. View the ID LED and do one of the following:  
ˆ If the ID LED is displaying a number from 1 to 4 (1 is the default),  
VCStack is already enabled on the switch. Power off the unit by  
disconnecting the power cord and test the remaining switches in  
the same manner. After testing all the switches, be sure the  
switches are powered off and go to Chapter 7, “Cabling the  
Stacking Ports” on page 91.  
ˆ If the ID LED is displaying “0,” the VCStack feature is disabled on  
the switch. You must enable it by performing the procedure in  
“Activating the VCStack Feature” on page 87.

ˆ “Powering On the Switches Individually” on page 102  
ˆ “Powering On the Switches Simultaneously” on page 104  
ˆ “Verifying the Stack” on page 106  
Perform “Powering On the Switches Individually” on page 102 if you want  
to control the assignment of the ID numbers to the switches of the stack.  
The numbers are assigned in the order in which you power on the units.  
Otherwise, perform “Powering On the Switches Simultaneously” on  
page 104 to have the switches assign the numbers automatically.  
After the ID numbers are assigned, you may change them with the STACK  
RENUMBER command, described in the Software Reference: AlliedWare  
Plus Operating System for IX5-28GPX Switches.  
Caution  
You should not change the ID numbers of the switches after you  
begin to configure the parameter settings. Otherwise, the stack  
might assign configuration settings to the wrong units.

Chapter 8: Powering On the Stack  
Powering On the Switches Individually  
This procedure explains how you can control the assignment of the ID  
numbers of the switches by powering on the units one at a time during the  
initial power-on sequence. The first switch is assigned ID number 1, the  
next unit is assigned ID number 2, and so on. This procedure is useful  
when the switches are installed in the same equipment rack and you want  
to number them in sequence, such as from top to bottom, to make them  
easy to identify. After the ID number are assigned, the switches retain their  
assignments even when you power off or reset the stack.  
During the initial power on sequence, the first switch to be powered on  
becomes the master switch of the stack. However, if you do not change  
the priority values of the units, the next time you reset or power cycle the  
stack the units use their MAC addresses to select the master switch. This  
might result in a different switch being assigned that role. However, this  
does not affect their ID number assignments, the configuration of the  
switches, or the manner in which you manage the stack.  
This procedure assumes the following:  
ˆ This is the initial power-on sequence of the stack.  
ˆ You verified that VCStack is enabled on the switches, as explained  
in Chapter 6, “Verifying the Status of VCStack and Activating  
VCStack” on page 85.  
ˆ You connected the switches with stacking transceivers, as  
explained in Chapter 7, “Cabling the Stacking Ports” on page 91.  
ˆ The ID numbers are set to the default 1.  
ˆ All the switches are powered off.  
If you want to monitor the power on sequence, you may connect a terminal  
or PC with a terminal emulator program to the Console port on the switch  
you intend to power on first. The messages are found in “Monitoring the  
Initialization Processes” on page 73.  
To power on the switches, perform the following procedure:  
1. Power on the switch you want to have ID number 1.  
Connect the power cords to the connectors on the power supply  
modules and to the appropriate power sources, as shown in  
“Connecting AC Power to a Power Supply Module” on page 70.  
2. Wait one minute for the switch to initialize its management software.  
The switch should be displaying the number 1 on its ID LED.  
3. Power on the switch to be assigned ID number 2.  
102  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
IX5-28GPX Installation Guide  
4. Wait two minutes for the new switch to join the stack as a member.  
As the new switch boots up, the first switch, which has the ID number 1  
and at this point is the master switch of the stack, notifies the new  
switch that its current ID number is already being used and that it  
should change its number to the next available number, which is 2. The  
new switch responses by automatically changing its ID number to 2  
and reboots. So the new switch is actually booting up twice, once with  
the ID number 1 and again with its new ID number 2, which is why it  
takes two minutes before the device becomes a full member of the  
stack.  
5. If there is a third switch, power it on and wait another two minutes for it  
to join the stack as a member with the ID number 3.  
6. If there is a fourth switch, power it on and wait two minutes for it to join  
the stack as a member with the ID number 4.  
At this point, the stack is operational.  
The ID numbers are automatically stored in special files in the flash  
memories of the switches and are retained by the devices even if you  
reset or power cycle the stack.  
7. To continue with the installation, go to “Verifying the Stack” on  
page 106.

Chapter 8: Powering On the Stack  
Powering On the Switches Simultaneously  
If you want the switches of the stack to use their MAC addresses to  
automatically assign the ID numbers during the initial power on sequence,  
all you have to do is power them on simultaneously, rather than one at a  
time as in the previous procedure. Here are the steps the switches  
perform:  
ˆ They initialize their management software and compare their MAC  
addresses.  
ˆ The switch with the lowest address is designated as the master  
switch of the stack.  
ˆ The master switch assigns itself the ID number 1.  
ˆ The master switch assigns ID numbers to the other switches.  
ˆ The other switches reset and initialize their management software  
again, with their new ID numbers.  
This procedure assumes the following:  
ˆ This is the initial power on sequence of the stack.  
ˆ You verified that VCStack is enabled on the switches, as explained  
in Chapter 6, “Verifying the Status of VCStack and Activating  
VCStack” on page 85.  
ˆ You connected the switches with stacking transceivers, as  
explained in Chapter 7, “Cabling the Stacking Ports” on page 91.  
ˆ .All the switches are powered off.  
If you want to monitor the power on sequence, you may connect a terminal  
or PC with a terminal emulator program to the Console port on any of the  
switches. The messages are found in “Monitoring the Initialization  
Processes” on page 73.  
To have the switches automatically assign the ID numbers, perform the  
following procedure:  
1. Power on all the switches in the stack at the same time.  
Connect the power cords to the connectors on the power supply  
modules and to the appropriate power sources, as shown in  
“Connecting AC Power to a Power Supply Module” on page 70.  
2. Wait two or three minutes for the switches to select a master switch  
and to assign the ID numbers.  
At this point, the stack is operational. The ID numbers are  
automatically stored in special files in the flash memories of the

Here are some things to consider:  
ˆ The command should list all the switches in the stack. If the list is  
incomplete, refer to Chapter 10, “Troubleshooting” on page 117.  
ˆ The Operational Status field displays “Normal operations” when  
the switches are connected in the ring topology and “Ring topology  
is broken” when the switches are connected in the linear topology.  
ˆ The priority values will be 128, the default value, if they have not  
been changed on the switches.  
ˆ Given that there is no relationship between the ID numbers and the  
selection of the master switch, the active master in the SHOW  
STACK command might not have the ID number 1.  
3. Do one of the following:  
ˆ If you want to change the priority values of the switches, go to  
“Setting the Priority Numbers” on page 107. The procedure is  
optional.

configuration should you ever power on the stack with a new member  
switch that has a lower MAC address than an existing master or member  
switch.  
This procedure assumes you are continuing directly on from the previous  
procedure.  
To set the priority values of the switches, perform the following procedure:  
1. Use the CONFIGURE TERMINAL command to move from the  
Privileged Exec mode to the Global Configuration mode, as shown in  
Figure 61.  
awplus# configure terminal  
Enter configuration commands, one per line. End with CNTL/Z.  
awplus(config)#  
Figure 61. Moving to the Global Configuration Mode with the CONFIGURE  
TERMINAL Command  
2. Use the STACK PRIORITY command to set the priority numbers. The  
command has this format:  
stack ID_number priority priority  
The ID_NUMBER parameter is the ID number of the switch whose  
priority value you are setting. The range is 1 to 4. The PRIORITY  
parameter is the new priority value for the switch. The range is 0 to  
255. The default is 128.  
Here are a couple of examples. To assign the priority value 1 to the  
switch with the ID number 1, you enter this command:  
awplus(config)# stack 1 priority 1  
To set the priority value to 2 on the switch with the ID number 2, you  
enter:  
awplus(config)# stack 2 priority 2  
3. After setting the priority values, enter the EXIT command to return to  
the Privileged Exec mode, as shown in Figure 62 on page 107.

Chapter 9: Cabling the Networking Ports  
Cabling the Twisted Pair Ports  
Here are the guidelines to cabling the 10/100/1000Base-T twisted pair  
ports:  
ˆ The cable specifications for the 10/100/1000Base-T twisted pair  
ports are listed in Table 2 on page 24 and Table 3 on page 25.  
ˆ The connectors on the cables should fit snugly into the ports, and  
the tabs should lock the connectors into place.  
ˆ The default setting for the wiring configurations of the ports is auto-  
MDI/MDI-X. The default setting is appropriate for switch ports that  
are connected to 10/100Base-TX network devices that also  
support auto-MDI/MDI-X.  
ˆ The default auto-MDI/MDI-X setting is not appropriate for switch  
ports that are connected to 10/100Base-TX network devices that  
do not support auto-MDI/MDI-X and have a fixed wiring  
configuration. For switch ports connected to those types of network  
devices, you should disable auto-MDI/MDI-X and set the wiring  
configurations manually.  
ˆ The appropriate MDI/MDI-X setting for a switch port connected to a  
10/100Base-TX network device with a fixed wiring configuration  
depends on the setting of the network device and whether the  
switch and network device are connected with straight-through or  
crossover cable. If you are using straight-through twisted pair  
cable, the wiring configurations of a port on the switch and a port  
on a network device must be opposite each other, such that one  
port uses MDI and the other MDI-X. For example, if a network  
device has a fixed wiring configuration of MDI, you must disable  
auto-MDI/MDI-X on the corresponding switch port and manually  
set it to MDI-X. If you are using crossover twisted pair cable, the  
wiring configurations of a port on the switch and a port on a  
network device must be the same.  
ˆ The default speed setting for the ports is Auto-Negotiation. This  
setting is appropriate for ports connected to network devices that  
also support Aut-Negotiation.  
ˆ The default speed setting of Auto-Negotiation is not appropriate for  
ports connected to 10/100Base-TX network devices that do not  
support Auto-Negotiation and have fixed speeds. For those switch  
ports, you should disable Auto-Negotiation and set the port’s  
speed manually to match the speeds of the network devices.  
ˆ The 10/100/1000Base-T ports must be set to Auto-Negotiation, the  
default setting, to operate at 1000Mbps.  
ˆ The default duplex mode setting for the ports is Auto-Negotiation.  
This setting is appropriate for ports connected to network devices  
that also support Auto-Negotiation for duplex modes.  
110  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
IX5-28GPX Installation Guide  
ˆ The default duplex mode setting of Auto-Negotiation is not  
appropriate for ports connected to network devices that do not  
support Auto-Negotiation and have a fixed duplex mode. You  
should disable Auto-Negotiation on those ports and set their duplex  
modes manually to avoid the possibility of duplex mode  
mismatches. A switch port using Auto-Negotiation defaults to half-  
duplex if it detects that the end node is not using Auto-Negotiation,  
which can result in a mismatch if the end node is operating at a  
fixed duplex mode of full-duplex.  
ˆ Do not attach cables to ports of static or LACP port trunks until  
after you have configured the trunks on the switch. Otherwise, the  
ports will form network loops that can adversely affect network  
performance.

Installing SFP and SFP+ Transceivers  
Review the following guidelines before installing SFP or SFP+  
transceivers in the switch:  
ˆ SFP and SFP+ transceivers are hot-swappable. You may install  
them while the chassis is powered on.  
ˆ Your Allied Telesis sales representative can provide you with a list  
of supported transceivers for the line cards.  
ˆ The operational specifications and fiber optic cable requirements  
of the transceivers are provided in the documents included with the  
devices.  
ˆ You should install a transceiver before connecting the fiber optic  
cable.  
ˆ Fiber optic transceivers are dust sensitive. Always keep the plug in  
the optical bores when a fiber optic cable is not installed, or when  
you store the transceiver. When you do remove the plug, keep it  
for future use.  
ˆ Unnecessary removal and insertion of a transceiver can lead to  
premature failure.  
Warning  
A transceiver can be damaged by static electricity. Be sure to  
observe all standard electrostatic discharge (ESD) precautions,  
such as wearing an antistatic wrist strap, to avoid damaging the  
device.  
Note  
SFP+ slots 27 and 28 are initially configured as stacking slots for the  
VCStack feature. If you intend to use the switch as a stand-alone  
unit, you must disable the VCStack feature before using the slots  
with standard SFP or SFP+ transceivers. See Chapter 5,  
“Configuring the Switch for Stand-alone Operations” on page 77 for  
instructions.

Troubleshooting  
This chapter contains suggestions on how to troubleshoot the switch if a  
problem occurs.  
Note  
For further assistance, please contact Allied Telesis Technical  
Support at www.alliedtelesis.com/support.  
Problem 1: The Switch ID LED on the front of the switch is off. The switch  
could be receiving no power, or the LED could be faulty.  
Solutions: Try the following:  
ˆ Check whether the switch is powered up, for example by listening  
for fan operation, checking the port LEDs and/or starting a  
management session. If it is powered up, then the Switch ID LED  
may be faulty. Please contact your Allied Telesis sales  
representative for assistance.  
Note  
The switch may be operating in low power mode, which reduces the  
number of lit LED segments. To toggle in and out of low power  
mode, press the eco-friendly button on the front panel of the switch.  
ˆ Check whether the PSU LED is lit. If the PSU LED is green:  
— Verify that the PSUs are correctly inserted. Each module must  
be flush with the rear panel of the switch. You may need to  
use light pressure to seat a PSU, but do not force it.  
— Try inserting the PSU into the other PSU bay.  
ˆ If the PSU LED is red, there may be a PSU fault. Please contact  
your Allied Telesis sales representative for assistance.  
ˆ If the PSU LED is not lit, then:  
— Verify that the power cord is securely connected to the power  
source and to the AC connector on the power supply module.  
— Verify that the power outlet has power by connecting another  
device to it.

Chapter 10: Troubleshooting  
— Try connecting the unit to another power source.  
— Try a different power cord.  
— Verify that the voltage from the power source is within the  
required levels for your region.  
Problem 2: All the port LEDs are off even though the ports are connected  
to active network devices.  
Solution: The switch may be operating in the low power mode. To toggle  
on the LEDs, press the eco-friendly button on the front panel of the switch.  
You may also toggle the LEDs off and on with the ECOFRIENDLY LED  
and NO ECOFRIENDLY LED commands in the command line interface.  
Problem 3: The SHOW STACK command is not displaying all the  
switches in the stack.  
Solutions: One or more switches cannot join the stack. Try the following:  
ˆ Verify that the stacking transceivers in the S1 and S2 slots of the  
switches are properly cabled. The stacking cables must crossover  
to different slots on the switches. For instructions, refer to Chapter  
7, “Cabling the Stacking Ports” on page 91.  
ˆ Verify that the transceivers are fully inserted into the S1 and S2  
slots.  
ˆ Verify that VCStack is activated on the switches. For instructions,  
refer to Chapter 6, “Verifying the Status of VCStack and Activating  
VCStack” on page 85.  
ˆ It could be that the switches have incompatible versions of the  
management software. When a stack forms or a new switch is  
added to an existing stack, the master switch downloads its  
management software to member switches that do not have the  
same version. If the master switch encounters a problem  
downloading the management software to a member switch, it  
does not allow the device to join the stack.

Problem 4: A twisted pair port on the switch is connected to a network  
device but the port’s LINK/ACT LED is off.  
Solutions: The port is unable to establish a link to a network device. Try  
the following:  
ˆ Verify that the port is connected to the correct twisted pair cable.  
This is to eliminate the possibility that the port is connected to the  
wrong network device.  
ˆ Verify that the network device connected to the twisted pair port is  
powered on and is operating properly.  
ˆ Try connecting another network device to the twisted pair port with  
a different cable. If the twisted pair port is able to establish a link,  
then the problem is with the cable or the other network device.  
ˆ Verify that the port speed, duplex and MDI settings are valid for the  
link partner. The easiest way to do this is to set all these  
parameters to auto-negotiate, which is the default setting. Also see  
Problem 6.  
ˆ Verify that the twisted pair cable does not exceed 100 meters (328  
feet).  
ˆ Verify that you are using the appropriate category of twisted pair  
cable. The cable types are listed in Table 2 on page 24 and  
Table 3 on page 25 for the 10/100/1000Base-T ports.  
Note  
A 1000Base connection may require five to ten seconds to establish  
a link.  
Problem 5: The LINK/ACT LED for an SFP or SFP+ transceiver is off.  
Solutions: The fiber optic port on the transceiver is unable to establish a  
link to a network device. Try the following:  
ˆ Verify that the remote network device connected to the fiber optic  
port is operating properly.  
ˆ Verify that the fiber optic cable is securely connected to the port on  
the SFP or SFP+ module and to the port on the remote network  
device.  
ˆ Check that the transceiver is fully inserted in the slot.  
ˆ If you are using SFP+ slots 27 and 28, check that VCStack is  
disabled on the switch. The VCStack feature has to be disabled  
before you can use these slots for regular SFP or SFP+  
transceivers. For instructions, refer to “Configuring the Switch for  
Stand-alone Operations” on page 78  
ˆ Verify that the operating specifications of the fiber optic ports on  
the transceiver and remote network device are compatible.

Chapter 10: Troubleshooting  
ˆ Verify that the correct type of fiber optic cabling is being used.  
ˆ Verify that the port is connected to the correct fiber optic cable.  
This is to eliminate the possibility that the port is connected to the  
wrong remote network device.  
ˆ Try connecting another network device to the fiber optic port using  
a different cable. If the port is able to establish a link, then the  
problem is with the cable or other network device.  
ˆ Use the switch’s management software to verify that the port is  
enabled.  
ˆ If the remote network device is a managed device, use its  
management firmware to determine whether its port is enabled.  
ˆ Test the attenuation of both directions on the fiber optic cable with  
a fiber optic tester to determine whether the optical signal is too  
weak (sensitivity) or too strong (maximum input power).  
Problem 6: Network performance between a twisted pair port on the  
switch and a network device is slow.  
Solution: There might be a duplex mode mismatch between the port and  
the network device. This can occur when a twisted pair port using auto-  
negotiation is connected to a remote device that has a fixed speed of 10 or  
100 Mbps and a fixed duplex mode of full duplex. If this is the cause of the  
problem, adjust the duplex mode of the port on the network device or  
switch so that both ports are using the same duplex mode. You can use  
either the LEDs or management software on the switch to determine the  
duplex mode settings of the ports. The LEDs are described in Table 4 on  
page 31.  
Problem 7: The switch functions intermittently.  
Solutions: Check the system hardware status through the management  
software:  
ˆ Use the SHOW SYSTEM ENVIRONMENT command in the  
Privileged Exec mode to verify that the input voltage from the  
power source to the switch is stable and within the approved  
operating range. The unit will shutdown if the input voltage  
fluctuates above or below the approved operating range.  
ˆ Use the SHOW SYSTEM ENVIRONMENT command in the  
Privileged Exec mode to verify that the fan is operating correctly.  
ˆ Verify that the location of the switch allows for adequate airflow.  
The unit will shutdown if it is in danger of overheating.

Problem 8: The Switch ID LED on the front of the switch is flashing the  
letter “F.”  
Solutions: One or more of the following problems has occurred:  
ˆ A cooling fan has failed.  
ˆ An unsupported PSU has been installed.  
ˆ One of the PSUs has failed.  
ˆ The input voltage on one or both of the PSUs is outside the normal  
operating range.  
ˆ The internal temperature of the switch has exceeded the normal  
operating range and the switch may shut down.  
Note  
You can use the SHOW SYSTEM ENVIRONMENT command in the  
command line interface to identify the source of the problem.  
Contact your Allied Telesis sales representative for assistance.Problem 9:  
The switch is not providing power to a PoE device.  
Solutions: Try the following:  
ˆ Review the PD’s documentation to confirm that the device supports  
Mode A of the IEEE 802.3at standard. Mode A is one of two modes  
that define the connector pins that deliver the power from the port  
on the line card to the PD. In Mode A, the power is carried on pins  
1, 2, 3, and 6 on the RJ-45 port, the same pins that carry the  
network traffic. The second mode, Mode B, defines pins 4, 5, 7,  
and 8 as the power carriers. The AT-IX5-28GPX switch does not  
support Mode B. Most powered devices are designed to accept  
power by either mode, but some legacy devices may only support  
one mode. This can be verified by reviewing the device’s  
documentation or data sheet. Legacy devices that only support  
Mode B will not work with the switch.  
ˆ Check that the device’s power requirements do not exceed its  
class limit (e.g. 30 W for PoE+). This can be verified by reviewing  
the device’s documentation or data sheet.  
ˆ Verify that you are using the appropriate category of twisted-pair  
cable by referring to Table 2 on page 24 or Table 3 on page 25.  
ˆ Use the management software on the switch to determine whether  
PoE is enabled on the port. The default setting for PoE is enabled.  
ˆ Use the management software on the switch to determine whether  
the PoE power setting for the port has been reduced to a value  
below the power requirements of the device.  
Try connecting the device to a different port on the switch.
