Quick Installation  
The Fast SwitcHub-2se contains 2 Ethernet ports that can operate at full-duplex or  
half-duplex. One of these ports supports 100BASE-TX or 10BASE-T (twisted-  
pair) connection, while the other port supports 100BASE-FX (fiber optic)  
connection. The smart design built into the front display panel and configure  
options, provides a friendly interface that simplifies installation and network  
troubleshooting. If you are already familiar with basic network operations, you  
should be able to install this switch as described below:  
1. Unpack the Fast SwitcHub-2se.  
2. Find a location close to the network devices you need to connect, and within  
easy reach of an electrical outlet.  
3. For 100BASE-TX or 10BASE-T devices, connect a workstation or server to  
the Port 1 MDI-X station port. Otherwise, you can connect to another switch  
or other network interconnection device by running straight-through twisted-  
pair cable between the MDI daisy-chain port on one device (e.g., Port 1 on  
this switch) to the MDI-X station port on the other device. Use 100W  
Category 5 STP or UTP cable to connect to the switch, and be sure the  
length of any twisted-pair connection does not exceed 100 meters.  
For integrating legacy networks, Port 1 provides for connection via either  
100BASE-TX or 10BASE-T. It uses auto-negotiation to dynamically set the  
required transmission speed at 10 or 100 Mbps.  
4. For 100BASE-FX devices, connect to Port 2 (i.e., connecting the Rx/Tx  
jacks on the target device to the Tx/Rx jacks on the switch). When  
connecting a node to Port 2, the maximum cable length is 2 kilometers if you  
are have a dedicated link (i.e., full-duplex mode); otherwise, the maximum  
length is 412 meters for a shared collision domain (i.e., a half-duplex  
connection). Refer to Chapter 2 for a more detailed description of  
calculating the maximum length permitted for fiber optic cable.

Fast SwitcHub-2se User’s Guide  
5. Set the transmission mode for each port to full or half-duplex. Full-duplex  
communications can only be supported for a dedicated link (i.e., set the  
communications to half duplex if you are connecting to a shared collision  
domain). Transmission must be set to full duplex or half duplex depending  
on the mode supported by the connected device. You must manually set the  
required mode with the configure button (Chapter 2).  
6. Verify network communications by ensuring that -  
• you have made all the necessary connections  
• you can access any connected resources  
• the switch’s indicator LEDs are functioning properly  
Note: For devices connected directly to either port on the switch, it will  
automatically detect transmission speed (10/100 Mbps). However, unless  
the connected devices are operating at half-duplex (i.e., system default), you  
will have to manually set the transmission mode via the configure button.  
(Refer to Full/Half Duplex Mode Selection in Chapter 2).  
If you encounter any problems in installing the Fast SwitcHub-2se, refer to Chapter  
2 for a detailed description of installation procedures, or to Appendix A for help  
in troubleshooting.

Chapter 1: Introduction  
Switching Technology  
The Ethernet Switch allows simultaneous transmission of multiple packets via  
an internal high-speed data channel. This means that it can partition a network  
more efficiently than bridges or routers. The Ethernet Switch is therefore fast  
being recognized as one of the most important building blocks for today’s  
networking technology.  
The learning function in the switch stores the address and corresponding port  
number of each incoming and outgoing packet in a routing table. This  
information is subsequently used to filter packets whose destination address is  
on the same segment as the source address. This confines network traffic to its  
respective domain, reducing the overall load on the network.  
The switch scans the destination address from the packet header, searches the  
routing table provided for the incoming port and forwards the packet only if  
required, often before fully received. This fast forwarding makes the switch  
attractive for connecting servers directly to the network, thereby increasing  
throughput and availability. However, the switch is most commonly used to  
segment existing hubs, which nearly always improves overall performance. A  
switch can be easily configured in any Ethernet network to significantly boost  
bandwidth using conventional cabling and adapters.

Accton’s Smart Extender  
Accton’s Fast Switch-2se can boost network bandwidth fourfold (i.e., if running  
at 100Mbps and using full-duplex operation for both ports). It provides one  
10/100 Mbps RJ-45 port for 10BASE-T or 100BASE-TX media attachment  
(which is automatically detected by the switch), and one 100 Mbps fiber optic  
port for 100BASE-FX media attachment via an SC or ST type connector.  
Either of these ports can be connected to a subnetwork, or directly to a server or  
key workstation, as well as set for full or half-duplex operation. Moreover, the  
fiber optic port can be used to significantly extend your network’s diameter.  
Note: The ES3002-TF-SC provides an SC-type fiber connector.  
The ES3002-TF-ST provides an ST-type fiber connector.  
In addition to partitioning an overloaded network, this switch provides  
connection between networks based on twisted-pair and fiber optic cabling, and  
can also be configured to operate in either full-duplex or half-duplex data  
transfer mode to support the interconnection requirements of high-speed  
devices.  
This switch performs “on-the-fly” cut-through switching, which passes a packet  
to the other port according to the destination address scanned from the packet  
header. This technique reduces the latency of packet transmission to 20  
microseconds or less. Compared to approximately 800 microseconds for a  
bridge or 1800 microseconds for a router, both of which have to store the entire  
packet before it can be forwarded, Accton’s SwitcHubs deliver a quantum  
improvement in your network's performance.  
As a device functioning on the media access control (MAC) layer, the Fast  
SwitcHub is protocol independent. Full compliance with IEEE802.3 and  
IEEE802.3u standards makes it transparent to upper-level protocols such as  
TCP/IP, NetWare, DECnet and XNS. Accton's Smart Extender can link high-  
speed 100BASE-TX or conventional 10BASE-T networks to the newer

generation of 100BASE-FX devices; or can be used to significantly extend a  
100BASE-TX or 10BASE-T network with an intermediate fiber optic link (i.e.,  
by chaining two or more switches). Moreover, by breaking your network into  
smaller and more manageable segments, each linked to the larger network with  
a switch, the maximum distance for communications between end-nodes is  
unlimited.  
Switching Methods  
Traditional bridges and routers use a switching method called store-and-  
forward in which the entire frame must be received before the bridge can  
perform a table look-up for the destination node and forward the packet to the  
corresponding port. As a result, each packet is delayed by approximately 800  
microseconds. It may be necessary to use store-and-forward when a lot of data  
errors are occurring over the network, or when connecting to very slow devices.  
Compared to this “safe” mode of operation, cut-through reduces the packet  
transmission delay to around 20 microseconds by picking the destination  
address out of the header as soon as its received, and directing the frame to the  
appropriate port long before the full packet has been received. The remaining  
technique, employed to improve data reliability, is called fragment-free cut-  
through. It uses a more conservative approach to cut-through that waits until  
the collision window has elapsed (i.e., the first full 64 bytes has been received)  
before processing the packet. This prevents runts from being passed along,  
effectively cleaning up the data stream.  
Although cut-though switching is recommended as the fastest method for most  
applications, the other methods mentioned above are also supported by the Fast  
SwitcHub-2se to guarantee flawless performance. To ensure that you can  
manage any kind of network load, the Smart Extender uses adaptive cut-  
through switching based on Accton’s smart algorithm. This method  
dynamically changes the way it handles data passing through the switch based

on the current error rate. These switching alternatives start at standard cut-  
through for a clean data environment, change to fragment-free cut-through for a  
moderate error rate, and then progress to store-and-forward for a highly  
contentious environment. By using this method, the Fast SwitcHub-2se  
delivers the best networking performance under any environment.  
Features of the Fast SwitcHub-2se

Chapter 2: Setup and Configuration  
This chapter provides information on pre-installation requirements, establishing  
network connections, and configuring the system.  
Pre-Installation Requirements  
Before you start making network connections to the SwitcHub, make sure you  
can provide the right operating environment, including power requirements,  
and proximity to other network devices that are to be connected. Verify the  
following installation requirements:  
• Power requirements: 100 to 240 VAC at 50 to 60 Hz. The switch’s power  
supply automatically detects the input voltage level.  
• The SwitcHub should be located in a cool dry place, with at least 10 cm. of  
space at the front and back for ventilation.  
• Check if network cables and connectors needed for installation are available.  
• Find a suitable location at the center of the devices you want to link, and  
near a power outlet.  
Connecting the Switch System  
The SwitcHub has one RJ-45 Ethernet port, and one fiber optic port (with SC or ST  
type connectors). Use twisted-pair cable to connect the RJ-45 MDI-X port to a  
server/workstation, or to connect the RJ-45 MDI port to another compatible switch  
or hub; and use 50/125 mm or 62.5/125 mm guage multimode fiber optic cable with  
SC or ST type connectors (depending on the SwitcHub model you purchased) to  
connect any compatible network device to the Rx/Tx jacks. The SwitcHub can be  
used to connect 100BASE-TX or 10BASE-T networks to a fiber optic backbone; or  
can be used to significantly extend a 100BASE-TX or 10BASE-T network with an  
intermediate fiber optic link (i.e., by chaining several switches).

Fast SwitcHub-2se User’s Guide  
Making RJ-45 Connections  
1. Prepare a straight-through twisted-pair cable with RJ-45 plugs at both ends.  
2. If you are making a connection to a server or workstation (i.e., a dedicated  
connection to an end-node device), be sure that it has a properly installed  
100BASE-TX or 10BASE-T network interface card. Attach one end of the  
cable to the MDI-X station port on the switch and the other end to the RJ-45  
port of the device’s network interface card. As a general rule, the length of  
twisted-pair cable forming a direct link between any two network devices  
should not exceed 100 meters.  
Note: Category 5 twisted-pair cable (100W) must be used for 100Mbps connections.  
Although Category 3, 4 or 5 cable can be used for 10Mbps connections, we highly  
recommend that you also use Category 5 cable for these connections to avoid any  
unnecessary expense or confusion if you subsequently upgrade to Fast Ethernet.  
If you are connecting to a network interconnection device, attach one end of  
the cable to the MDI crossover port on the switch and the other end to an  
MDI-X station port on the other device (or vice versa). When cascading to  
devices other than this switch, please refer to the accompanying  
documentation for restrictions on stack size. Also note that because the  
switch breaks up the path for connected devices into separate collision  
domains, you should not include the switch or connected cabling in your  
calculations for cascade length involving other devices.  
Note: In contrast to repeater hubs, a cascade of switches breaks up the collision  
domain. The number of switches that can be cascaded is therefore theoretically  
unlimited. However, in practice, the length of a cascade may be limited by the time-  
out requirements of the particular applications running over the network.  
3. Set the communication mode via the Configure button to full-duplex or  
half-duplex mode to match the connected device. (Refer to Setting the  
Communication Mode in Chapter 3.)  
Do not plug a phone jack connector into the RJ-45 port. This may damage the  
switch. Instead, use only twisted-pair cables with RJ-45 connectors that conform  
to FCC standards.

2. If you are making a connection to a server or workstation, be sure it that has  
a properly installed 100BASE-FX network interface card. Connect the Rx/Tx  
jacks on the target device to the Tx/Rx jacks on the switch.  
Distance Limit and Power Loss in Fiber Optics - When using fiber optic cabling,  
the maximum length between two switches can be up to 2 kilometers.  
However, you must consider power loss when calculating the actual length of  
cable that can be used with your system. You can calculate power loss with the  
following formula:  
(p dB - i dB)  
m =  
Variable

Note: To determine the power loss incurred by intervening devices and specific cable  
type, inquire with the manufacturer. The power budget depends on the gauge of cable  
as shown below.

Fast SwitcHub-2se User’s Guide  
For a sample calculation, assume the following values:  
• cable gauge - 62.5/125 mm, which means a 13 dB power budget,  
• 2 patch panels between the switches, each with 0.5 dB power loss, and  
1 splice with 0.4 dB power loss (i.e., 2 * 0.5 + 0.4 = 1.4 dB power loss for  
intervening devices), and  
• inherent power loss in the cable is 4.5 dB/km  
The maximum cable length is therefore:  
13 dB - 1.4 dB  
m ≤  
≤ 2.58 km  
4.5 dB/km  
When the 100BASE-FX link is used for a dedicated connection (i.e.,  
full-duplex communications), cable length should not exceed 2  
kilometers. However, when the link is used for a shared collision  
domain (i.e., half-duplex communications), cable length should not  
exceed 412 meters (IEEE 802.3u).  
I
Note: Even though your calculations for power loss may indicate a longer permissible  
length based on signal strength (as seen in the preceding example), we advise remaining  
within the recommended limits.  
3. Set the communication mode via the Configure button to full-duplex or  
half-duplex mode to match the connected device. (Refer to Setting the  
Communication Mode in Chapter 3.)

Providing Power to the SwitcHub  
1. Power on the switch by plugging the power cord into the power socket at the  
rear of the SwitcHub, and the other end into a power outlet.  
2. Check the LED marked Power on the front panel to see if it is on. The unit  
will automatically select the setting that matches the connected input voltage.  
Therefore, no additional adjustments are necessary when connecting it to any  
input voltage within the range marked on the rear panel.  
3. The SwitcHub performs a self-diagnostic test upon power on. (Note that this  
test takes about 50 seconds to complete.) For details about the system self-  
diagnostic test, refer to the following section.  
Diagnostic Tests  
Upon Power On  
Upon power on, the system performs an internal self-diagnostic test of major  
switch components. If any component fails during the test, the switch will try  
to complete the diagnostic procedure. Otherwise, the system will hang. For  
related information, refer to Diagnostics Display Mode in Chapter 3.  
The components to be tested include:  
• System ROM  
• System EEPROM  
• Ports 1 - 2  
During Normal Operation  
You can use the Configure button any time you want to perform a diagnostic  
test. When testing begins, the system leaves normal operation. If no problem  
is encountered by the diagnostic test, the system automatically returns to  
normal operation.

Verifying System Operation  
Verify that all attached devices have a valid connection. The switch monitors  
link status for each port. If any device is properly connected to the switch and  
transmitting a link beat signal, the Link indicator lights up for the corresponding  
port. If the Link indicator fails to light up when you connect a device to the  
switch, check the following items -  
• Be sure the twisted-pair cable is properly attached to the connected device  
and the switch. Verify that the RJ-45 plug snaps into place when attached.  
• See if the twisted-pair cable is functioning properly by using it for another  
port and attached device that displays valid indications when connected to  
the network.  
• Check the length of the twisted-pair cable to be sure it does not exceed 100  
meters.

Chapter 3: Hardware Reference  
The Fast SwitcHub-2se is a highly reliable network switch that complies with  
IEEE 802.3 (10BASE-T) and IEEE 802.3u (100BASE-TX and 100BASE-FX)  
specifications. This switch delivers superior performance compared to the  
bridge and router solution, and at a much lower cost. By confining local traffic  
to the originating segment, and only forwarding cross-segment traffic to the  
other port, this switch meets the requirements for Ethernet and IEEE 802.3  
networks.  
This chapter describes the hardware features of the Fast SwitcHub-2se. For  
easier management and control of the switch, familiarize yourself with the  
display indicators, ports and configure button. Front and rear panel illustrations  
in this chapter display the unit’s LED indicators, configure button and ports.  
Front Panel  
The unit’s front panel provides a simple interface for configuring or monitoring  
the switch. It includes a configure button, power indicator, display mode  
indicators, port status indicators, and a statistical display for network traffic as  
shown below.

Configure Button  
The Configure button is located on the left front panel. This button is used to  
select the following configuration functions:  
• System Performance (displays relative bandwidth utilization rate, forwarding  
ratio, filtering ratio, and collision ratio for each port)  
• Full/Half Duplex (sets port communication mode to full-duplex or half-  
duplex operations)  
• Diagnostics (tests the status of various system components)  
To set system performance or diagnostic mode –  
1. To start configuration use a “long press” on the Configure button. The  
indicators will light up to show the selected configuration function. (Refer  
to the related sections in this chapter and to Chapter 2 for complete details.)  
2. To scan through the configuration functions use a “short press” on the  
Configure button. (For information on how to select Full/Half duplex  
communications, refer to the section on Setting the Communication Mode.)  
3. To accept and implement the current settings use a “long press” on the  
Configure button.  
“Long press” means pressing the Configure button for more than 2 seconds and  
Fthen releasing it. While “short press” means pressing the Configure button and  
immediately releasing it. Also, note that if this button is not pressed within 10  
seconds, the system returns to normal operation.

data passing through each port compared to overall network bandwidth (updated  
every 0.5 seconds). There are 8 LEDs representing the percentage of network  
utilization. The corresponding LEDs light up to show that the utilization of LAN  
bandwidth has reached this percentage. When active, these LEDs behave like a  
stereo’s equalizer display.

Fast SwitcHub-2se User’s Guide  
For example, if network utilization reaches 1%, the LED labeled 1% will light up.  
However, if network utilization rises above 35%, the LED labeled 35 and all the  
other LEDs before it (i.e., 1, 5, 10 and 20) will also light up in rapid succession.  
These indicators monitor the share of valid network frames handled by each port  
within a 10Mbps or 100Mbps bandwidth, depending on the Ethernet type  
currently plugged into the back panel. They provide a quick way to monitor the  
current traffic load relative to the network’s capacity.  
Forward Display Mode (Forward%) - The statistical indicators show the percentage of  
packets that must be forwarded by bridging hardware to the other port on the  
switch (i.e., another LAN segment or connected workstation). When viewing  
the Forward% indications, remember that under normal conditions, the  
SwitcHub forwards 100% of all Ethernet packets that must be transferred among  
the connected LAN segments at line speed.  
Filter Display Mode (Filter%)- The statistical indicators show the percentage of  
packets that must be filtered from the switch by hardware because the  
destination address is on the same segment connected to the receiving port.  
When viewing the Filter% indications, remember that under normal conditions,  
the SwitcHub filters 100% of all Ethernet packets that belong to the local LAN  
segments at line speed (i.e., no local traffic leaks through to the other segment).  
Collision Display Mode (Coll%)- The statistical indicators show the percentage of packet  
collisions occurring out of the total packets transmitted by the port. Collisions  
occur when two or more devices connected to a switch attempt to transmit data  
simultaneously on the network. When a collision occurs, devices use a back-off  
scheme that forces them to pause and then re-transmit after a pseudo-random wait  
period. Because wait periods differ among devices, successive collisions become  
increasingly improbable.  
The Collision LEDs assist the network manager in monitoring the percentage of  
packet collisions occurring relative to the total packets transmitted by each port.  
The collision indicators are labeled by row to indicate the percentage of  
Hardware Reference

Download from Www.Somanuals.com. All Manuals Search And Download.  
Fast SwitcHub-2se User’s Guide  
collisions encountered by the corresponding port. When collisions reach a  
level marked on the front panel display, the corresponding LED lights up. For  
example, if packet collision reaches 1%, the LED labeled 1% will light up.  
However, if collisions go beyond 30%, the LED labeled 30+% and all the other  
LEDs before it (i.e., 1, 5, 10 and 20) also light up in rapid succession.  
Note: If either port displays a high collision rate, check to see if any of the connected  
devices are malfunctioning or if a loop has been formed in your network connections.  
Otherwise, you may need to reconfigure your network to balance the traffic load.

hubs use a common collision domain for all communications, and therefore  
cannot support full-duplex mode. When connecting the SwitcHub to a repeater  
hub, use a standard cascaded connection set for half-duplex communications.

Ethernet Ports  
The SwitcHub has 2 Ethernet ports – one is used for 100BASE-TX or  
10BASE-T media and the other for 100BASE-FX media.  
100BASE-TX or 10BASE-T – The STP RJ-45 port pair provides one MDI-X port  
for connecting to a workstation or server and one MDI port for connecting to  
another network interconnection device, such as a hub or switch. When using  
Fast Ethernet, these ports can also be connected to devices such as a high-speed  
server or Ethernet backbone. Use straight-through twisted-pair cable to connect  
to either the MDI or MDI-X switching port (not both).  
100BASE-FX – This port provides Rx/Tx jacks for connecting any compatible  
network device using multimode fiber optic cable with SC or ST type connec-  
tors. Mate the Rx/Tx jacks with the Tx/Rx jacks on the target device.

Appendix A: Troubleshooting  
Diagnosing Switch Indicators  
The Fast SwitcHub-2se can be easily monitored through its comprehensive  
panel indicators. These indicators assist the network manager in identifying  
problems the switch may encounter. This section describes common problems  
you may encounter and possible solutions.  
Symptom: Link indicator does not light up (green LED) after making a connection.  
Cause:  
Workstation’s network adapter, cable or switch port is defective.  
Solution: The most common cause for a bad connection to a workstation or  
server is a defective network adapter or cable connection. Check the  
workstation’s network adapter and cable connections for possible  
defects. Replace the defective adapter or cable.  
Symptom: Power indicator does not light up (green LED) after power on.  
Cause:  
Defective power supply or CPU  
Solution: Have your unit’s power supply or CPU replaced. Ask for dealer  
assistance.  
Use the diagnostic procedures described in Chapters 2 and 3 to verify that all  
other system components are functioning properly. If any component fails the  
diagnostic test, contact your Accton distributor for assistance.

Installation  
Verify that all system components have been properly installed. If one or more  
components appear to be malfunctioning, test them in an alternate environment  
where you are sure that all the other components are functioning properly.  
Transmission Mode  
Be sure each port on the SwitcHub is set to the same transmission mode as the  
attached device; i.e., full duplex or half duplex. (Refer to Setting the Communica-  
tion Mode in Chapter 3 for a detailed description.)  
Cabling  
1. Verify that the cabling type is correct. Be sure all cable connectors are  
securely seated in the required ports. Straight-through cable should be used  
for all standard twisted-pair connections; and multimode cable with SC or  
ST type connectors should be used for fiber optic connections.  
2. Make sure all devices are connected to the network. Equipment may have  
been unintentionally disconnected from the network.  
External Adapters  
Make sure the network adapter cards installed in the workstations are  
compatible with your network media type and are in good working condition.
