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 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.
For the temperature and humidity requirements, see "Appendix A Chassis views and technical
specifications."
2
Cleanness
Dust buildup on the chassis might 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 1 Dust concentration limit in the equipment room
Substance Concentration limit (
p
articles/m³)
Dust 3 x 104 (no visible dust on the tabletop over three days)
NOTE:
Dust diameter 5 μm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 2.
Table 2 Harmful gas limits in the equipment room
Gas Maximum concentration (m
g
/m3)
SO2 0.2
H2S 0.006
NH3 0.05
Cl2 0.01
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.
W
ARNING!
Do not stare into any fiber port when the switch has power. The laser li
g
ht emitted from the optical fiber
might 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 might occur.
Select the installation location carefully. In the case of poor surface, magnet mounting might not be
reliable.
Put the switch at a stable place free from vibrations or shocks. Otherwise, personal injuries or equipmen
t
damage might occur.
Avoid installing the switch at a high place because bodily injuries or equipment damage might occur in
case of a falloff.
Avoid frequently moving the desk-mounted switch because such movements might dama
g
e 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 the weight of external cables does not bring about a falloff, which might 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 might occur to these electronic devices.
To complete magnet mounting:
1. Use a Phillips screwdriver to pass the countersunk head screw through the round hole at the center
of the permanent magnet, fasten it to a blind nut in the dent of the switch bottom, and make sure
the permanent magnet and the switch are fastened reliably. See Figure 28.
IMPORTANT:
Remove the cushion, if any, from the dent before installation.
To ensure the firmness of installation, be sure to use four permanent magnets to secure each switch.
2. Attach the magnet-mounted switch to the specified location. Do not get your fingers stuck between.

Grounding the switch
W
ARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
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
Grounding the switch with a grounding conductor buried in the earth ground
Grounding the switch by using the AC power cord
Grounding the switch with a grounding strip
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.

The 5120 EI series, 5120-24G-PoE+ SI, and 5120-24G-PPoE+ SI switches come with a ring terminal for
connecting to a grounding strip. For other switch models, you must prepare ring terminals yourself.
To connect the grounding cable, for example, to a 5120-48G EI (2 slots) switch:
1. Identify the grounding point (with a grounding sign) on the rear panel of the switch chassis, and
remove the grounding screw from the grounding point.
2. Attach the grounding screw to the ring terminal of the grounding cable.
3. Use a screwdriver to fasten the grounding screw into the grounding screw hole.

5. Cut the grounding cable as appropriate for connecting to the grounding strip.
6. Make the connector for connecting to the grounding strip:
{ If a ring terminal is available, peel 5 mm (0.20 in) of insulation sheath by using a wire stripper,
and insert the bare metal part through the black insulation covering into the end of the ring
terminal, secure the metal part of the cable to the ring terminal with a crimper, cover the joint
with the insulation covering, and heat the insulation covering with a blow dryer to completely
cover the metal part (see callout A in Figure 30).
{ If no ring terminal is available, peel the insulation sheath as appropriate by using a wire stripper,
and bend the bare metal part into a ring (see callout B in Figure 30). Attach the ring terminal
or the ring to the grounding strip through the grounding post, and fasten it with the removed hex
nut, see Figure 31.

earth ground
If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft) or
longer angle iron or steel tube into the earth ground to serve as a grounding conductor.
The dimensions of the angle iron must be at least 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel tube
must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).
Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion
protection.

Powering on the switch
Before powering on the switch, verify that the following conditions are met:
The power cord is correctly connected.
The input power voltage meets the requirement of the switch.
The console cable is correctly connected.
The configuration terminal (a PC, for example) has started, and its serial port settings are consistent
with the console port settings on the switch.
Power on the switch. During the startup process, you can access Boot ROM menus to perform tasks such
as software upgrade and file management. The Boot ROM interface and menu options differ with
software versions. For more information about Boot ROM menu options, see the software-matching
release notes for the device.
After the startup completes, you can access the CLI to configure the switch.
For more information about the configuration commands and CLI, see the configuration guides and
command references for the switch.

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 documen
t
does not include those two switch models.
An IRF fabric cannot have both 5120 EI and 5120 SI switches.

1. Plan IRF fabric setup
Plan the installation site and IRF fabric setup parameters:
Planning IRF fabric size and the installation site
Identifying the master switch and planning IRF member IDs
Planning IRF topology and connections
Identifying physical IRF ports on the member switches
Planning the cabling scheme
2. Install IRF member
switches See "Installing the switch."
3. Connect the grounding
cable and power cords See "Grounding the switch" and "Connecting the power cord."
4. Power on the switches N/A
5. Install interface cards This step is required only for the 5120 EI switches.
See "Installing/removing an interface card (only for the 5120 EI switches)."
6. Configure basic IRF
settings See "Configuring basic IRF settings."
7. Connect the physical IRF
ports
See "Connecting the physical IRF ports."
All switches except the master switch automatically reboot, and the IRF fabric
is established.
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.

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.
39
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 49 and Figure 50 show the topologies of a 5120 EI IRF fabric. Figure 51 and Figure 52 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
5120 EI switches
(excluding the 5120-24G
EI and the 5120-48G EI)
Ports on the expansion
interface cards on the
rear panel
You must order interface cards separately. For
long-distance connections, use XFP/SFP+
transceiver modules and fibers. For short-distance
connections, use CX4/SFP+ cables or twisted-pair
cables. For more information, see "Interface cards
(only for the 5120 EI switches)" and
"SFP/SFP+/XFP transceiver modules and
SFP+/CX4 cables (only for the 5120 EI switches)."
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.
5120 SI switches All network ports
HP recommends that you use Gigabit SFP ports and
HP A3600 Switch SFP Stacking Kit cables for IRF
connection.
For more information, see "SFP transceiver modules
and SFP Stacking Kit (only for the 5120 SI switches)."
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 Figure 53.
Figure 53 Use 2-port interface cards to set up single-link IRF connection
42
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
54. For example, you can connect the left port on one interface card to the left or right port on the
other interface card.
Figure 54 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
the port on MOD 2 on the other switch (see callout 1 in Figure 55).
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
port on the 2-port interface card (see callout 2 in Figure 55.)
{ 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 56 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 57 shows the IRF fabric topology.
Figure 56 Connect the IRF member switches
Figure 57 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.
44
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:
W
ear 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. Log in to the IRF fabric through the console port of any member switch.
2. Create a Layer 3 interface, assign it an IP address, and make sure 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. Verify that you can manage all member switches as if they were one node.
5. Display the running status of the IRF fabric by using the commands in the table bellow.
Task Command
Display information about the IRF fabric. display irf
Display all members’ configurations that take
effect after switch reboots. display irf configuration
Display topology information about the IRF
fabric. display irf topology
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.

Maintenance and troubleshooting
Power supply failure
The 5120 EI switches and the 5120 SI switches use built-in 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
information, see "LEDs (for the 5120 EI switches)."
On the 5120-24G-PoE+ SI switch, look at the power LED and the RPS status LED of the switch. For
more information, see "LEDs (for the 5120 SI switches)."
On any other 5120 SI switch, look at the power LED of the switch. For more information, see "LEDs
(for the 5120 SI switches)."
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.
46
{ 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. 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.
3. 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.
{ The RPS is correctly working.
NOTE:
If the problem persists, contact the HP technical support for help.
Fan failure (only for the 5120 EI switches)
You can look at the system status LED and the seven-segment LED of a 5120 EI switch to identify a fan
failure. If both LEDs are behaving as described in Table 9, a fan failure occurs.

The 5120 EI switches use built-in fans. If a fan failure occurs, contact the HP technical support for help and
do not attempt to fix the problem yourself.
Configuration terminal problems
If the configuration environment setup is correct, the configuration terminal displays booting information
when the switch is powered on. If the setup is incorrect, the configuration terminal would display nothing
or garbled text.
No terminal display
If the configuration terminal displays nothing after the switch is powered on, verify the following items:
The power supply is supplying power to the switch.
47
The console cable is correctly connected.
The console cable has no problem and the terminal settings are correct.
Garbled terminal display
If terminal display is garbled, verify that the following settings are configured for the terminal, for
example, HyperTerminal:

On a 5120 EI switch, the last four 10/100/1000Base-T Ethernet ports and the four SFP ports are
copper/fiber combo ports in pairs, as shown in Table 15. They form four combo interfaces. When one
port in a pair is activated, the other port automatically shuts down. For more information about combo
interfaces, see HP 5120 EI Switch Series Configuration Guides.
