Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.
•
•
Before cleaning the switch, unplug all power cords. Do not clean the switch with wet cloth or liquid.
Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
•
•
Do not place the switch on an unstable case or desk. The switch might be severely damaged in case
of a fall.
Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents of the switch
free of obstruction.
•
•
Make sure that the operating voltage is in the required range.
To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch
is just powered off.
•
When replacing FRUs, wear an ESD-preventive wrist strap to avoid damaging the units.
Examining the installation site
The 5120 EI and 5120 SI switches must be used indoors. You can mount your switch in a rack or on a
workbench, but make sure:
•
•
•
•
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
The rack or workbench has a good ventilation system.
The rack is sturdy enough to support the switch and its accessories.
The rack or workbench is well earthed.
To ensure normal operation and long service life of your switch, install it in an environment that meets the
requirements described in the following subsections.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
•
•
•
Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
Lasting low relative humidity can cause washer contraction and ESD and bring problems including
loose captive screws and circuit failure.
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the switch.
13
Download from Www.Somanuals.com. All Manuals Search And Download.
Cleanness
Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal
components and contact points, especially when indoor relative humidity is low. In the worst case,
electrostatic adsorption can cause communication failure.
Table 4 Dust concentration limit in the equipment room
Substance
Concentration limit (particles/m³)
Dust
≤ 3 x 104 (no visible dust on the tabletop over three days)
NOTE:

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To
prevent EMI, take the following actions:
•
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to
filter interference from the power grid.
•
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or
overcurrent caused by lightning strikes.
Laser safety
The HP 5120 EI and 5120 SI switches are Class 1 laser devices.
WARNING!
Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber
may hurt your eyes.

CAUTION:
• Apply magnet mounting to only the 5120-8G SI, 5120-8G-PoE+ SI, and 5120-8G-PPoE+ SI. Otherwise,
a falloff or mis-operation may occur.
• Select the installation location carefully. In the case of poor surface, magnet mounting may not be
reliable.
• Put the switch at a stable place free from vibrations or shocks. Otherwise, personal injuries or equipment
damage may occur.
• Avoid installing the switch at a high place because bodily injuries or equipment damage may occur in
case of a falloff.
• Avoid frequently moving the desk-mounted switch because such movements may damage the surface
coating.
• To install the device vertically, keep the front panel of the switch facing downwards and the two sides
with ventilation holes vertical to the ground.
• Make sure that the weight of external cables does not bring about a falloff, which may result in bodily
injuries or equipment damage.
• Keep magnetic cards away from magnets to avoid erasure of any information.
• Keep computers and monitors that are easily influenced by magnetic fields away from magnets.
Otherwise, faults may occur to these electronic devices.
Grounding the switch
WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
NOTE:
The power and grounding terminals in this section are for illustration only.
The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis
ground to the earth so the faradism and leakage electricity can be safely released to the earth to
minimize EMI susceptibility of the switch.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:
•
•
•
Grounding the switch with a grounding strip
If a grounding strip is available at the installation site, connect the grounding cable to the grounding

Setting up an IRF fabric
You can use HP Intelligent Resilient Framework (IRF) technology to connect and virtualize 5120 EI switches
or 5120 SI switches into a virtual switch called an “IRF fabric” or “IRF virtual device” for flattened network
topology, and high availability, scalability, and manageability.
NOTE:
• IRF is not available on the 5120-24G EI or 5120-48G EI switch. The “5120 EI switches” in this document
does not include those two switch models.
• An IRF fabric cannot have both 5120 EI and 5120 SI switches.

Planning IRF fabric setup
Planning IRF fabric size and the installation site
Choose switch models and identify the number of required IRF member switches, depending on the user
density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the total
switching capacities of all member switches.
NOTE:
As your business grows, you can plug a switch into an IRF fabric to increase the switching capacity without
any topology change or replacement.
Identifying the master switch and planning IRF member IDs
Determine which switch you want to use as the master for managing all member switches in the IRF fabric.
An IRF fabric has only one master switch. You configure and manage all member switches in the IRF
fabric at the command line interface of the master switch.
NOTE:
IRF member switches will automatically elect a master. You can affect the election result by assigning a
high member priority to the intended master switch. For more information about master election, see the
IRF configuration guide for your switch.
Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and
manage its members, and you must assign each IRF member switch a unique member ID.
54
Download from Www.Somanuals.com. All Manuals Search And Download.
Planning IRF topology and connections
You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology,
the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF
fabric changes to a daisy chain topology without interrupting network services.
You connect the IRF member switches through IRF ports. An IRF port is a logical interface for the internal
connection between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and
IRF-port 2. To use an IRF port, you must bind physical ports to it.
When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port
1 on one switch to the physical ports of IRF-port 2 on the other switch.
You can bind several physical ports to an IRF port to create an aggregate IRF link for increased
bandwidth and availability.
NOTE:
• Figure 77 and Figure 78 show the topologies of a 5120 EI IRF fabric. Figure 79 and Figure 80 show the
topologies of a 5120-24G SI IRF fabric.
• The IRF port connections in these figures are for illustration only, and more connection methods are

Requirements
•
You must order interface cards separately. For
long-distance connections, use XFP or SFP+
transceiver modules and fibers. For short-distance
connections, use CX4 or SFP+ cables. For more
information, see “Interface cards (only for the

•
Ports assigned to the same IRF port must be on the
same interface card.
All 5120 EI switches in a ring topology and the
non-edge switches in a daisy chain topology must
have at least one two-port interface card or two
one-port interface cards.
HP recommends that you use Gigabit SFP ports and
HP A3600 Switch SFP Stacking Kit cables for IRF
connection.

Planning the cabling scheme
Planning the cabling scheme for a 5120 EI IRF fabric
If 2-port interface cards are used and the IRF links are not aggregate, follow these guidelines on
connecting two neighboring 5120 EI switches:
•
You can connect the interface card in slot 1 (MOD 1) on a member switch to the MOD 1 or MOD
2 card on its neighboring switch.
•
Connect the left port on one interface card to the right port on the other interface card, as shown in

If 2-port interface cards are used and IRF links are aggregate, follow these guidelines on connecting two
neighboring switches:
•
The ports on the interface card MOD 1 on one switch must connect to the ports on the interface card
MOD 2 on the other switch.
•
A port on one interface card can connect to any port on the other interface card, as shown in Figure
82. For example, you can connect the left port on one interface card to the left or right port on the
other interface card.
Figure 82 Use 2-port interface cards to set up multi-link IRF connection
If 1-port interface cards are used, follow these guidelines on connecting neighboring switches:
•
If both of the switches use 1-port interface cards, the port on MOD 1 on one switch must connect to
•
If one switch uses a 1-port interface card but the other switch uses a 2-port interface card:
{
If the 1-port interface card is in the MOD 1 slot, the port on the card must connect to the right
{
If the 1-port interface card is in the MOD 2 slot, the port on the card must connect to the left port
on the 2-port interface card.

Planning the cabling scheme for a 5120 SI IRF fabric
HP recommends that you use Gigabit SFP ports and HP A3600 Switch SFP Stacking Kit cables for IRF
connection.
Figure 84 shows two IRF connection schemes and uses Gigabit SFP ports and HP A3600 Switch SFP
Stacking Kit cables for IRF connection. All these schemes use a ring topology.
Figure 85 shows the IRF fabric topology.

Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see the fundamentals configuration guide for your switch) to configure their member IDs, member
priorities, and IRF port bindings.
Follow these guidelines when you configure the neighboring switches:
•
•
Assign the master switch higher member priority than any other switch.
Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch.

•
•
Execute the irf-port-configuration active command to activate the IRF port configuration.
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see the IRF configuration guide for your switch.
Connecting the physical IRF ports
Connect the IRF member switches as planned.
NOTE:
Wear an ESD-preventive wrist strap when you connect the physical IRF ports. For how to connect them,
see Pluggable SFP/SFP+/XFP Transceiver Modules Installation Guide.
Accessing the IRF fabric to verify the configuration
To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and
connecting IRF ports:
1.
2.
Log in to the IRF fabric through the console port of any member switch.
Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the
remote network management station can reach each other.
3.
Use Telnet, web or SNMP to access the IRF fabric from the network management station.
See the fundamentals configuration guide for your switch.
4.
5.
Check that you can manage all member switches as if they were one node.
Table 13 Display and maintain IRF configuration and running status
To do …
Use the command…

NOTE:
To avoid IP address collision and network problems, configure at least one multi-active detection (MAD)
mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more
information about MAD detection, see the IRF configuration guide for your switch.

Power supply failure
The 5120 EI switches and the 5120 SI switches use fixed power supplies. All 5120 EI switches and the
5120-24G-PoE+ SI switch support three power input modes: AC input, RPS DC input, and concurrent AC
and RPS DC inputs. All other 5120 SI switches have only one AC power input.
To identify a power failure:
•
•
•
On any 5120 EI switch, look at the system status LED and the RPS status LED of the switch. For more

NOTE:
In the following subsections, the system status LED collectively refers to both the system status LED on a
5120 EI switch and the power LED on a 5120 SI switch.
AC input
If the system status LED is off, an AC input failure has occurred. Verify the following items:
•
The AC power cord is securely connected to the switch, and the AC-input power receptacle on the
switch and the connected AC power outlet are in good condition.
•
•
The external AC power system is correctly working.
The operating temperature of the switch is in the normal range, and the power module has good
ventilation. Over-temperature can cause the power module to stop working and enter the protection
state.
RPS DC input
If the system status LED or RPS status LED is off, an RPS input failure has occurred. Verify the following
items:
•
•
•
The switch is securely connected to the RPS.
The RPS is correctly working.
The operating temperature of the switch is in the normal range, and the power supply has good
ventilation. Over-temperature can cause the power supply to stop working and enter the protection
state).
Concurrent RPS and AC inputs
1.
If the system status LED is off, the AC power supply and the RPS both have an input failure.
Verify the following items:
{
The AC power cord is securely connected to the switch, and the AC-input power receptacle on
the switch and the connected AC power outlet are in good condition.
{
{
{
{
The external AC power system is correctly working.
The switch is securely connected to the RPS.
The RPS is correctly working.
The operating temperature of the switch is in the normal range, and the power supply has good
ventilation. Over-temperature can cause the power supply to stop working and enter the
protection state.
2.
3.
If the system status LED is on but the RPS status LED is steady yellow, an AC input failure has
occurred.
Verify the following items:
{
The AC power cord is securely connected to the switch, and the AC-input power receptacle on
the switch and the connected AC power outlet are in good condition.
{
The external AC power system is correctly working.
If the system status LED is on but the RPS status LED is off, an RPS input failure has occurred.
Verify the following items:
{
The switch is securely connected to the RPS.
