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 from the switch. 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.
•
Connect the yellow-green protection grounding cable before power-on.
•
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, including power supplies and fan trays, wear an ESD-preventive wrist strap
to avoid damaging the units.
Examining the installation site
The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches must be used indoors.
Mount your switch in a rack and make sure:
•
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
•
The rack has a good ventilation system.
•
Identify the hot aisle and cold aisle at the installation site, and make sure that ambient air flows into
the switch from the cold aisle and exhausts to the hot aisle.
•
Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the bottom
device from entering the top device.
•
The rack is sturdy enough to support the switch and its accessories.
•
The rack 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.
4
•
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 of different switch models, see “Appendix A Technical
specifications.”
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.

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.
5
Laser safety
The HP 5920 and 5900 series 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.

Attaching the mounting brackets, chassis rails, and grounding
cable to the chassis
The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches have one front mounting position (near the
network ports) and one rear mounting position (near the power supplies).
The HP 5920AF-24XG has one primary grounding point (with a grounding sign) and one auxiliary
grounding point, and the HP 5900AF-48XG-4QSFP+ switch has one primary grounding point (with a
grounding sign) and two auxiliary grounding points. Use the primary grounding point whenever
possible. If the primary grounding point fails or is not suitable for the installation site, use one of the
auxiliary grounding points.

4.
If the mounting brackets are in the rear mounting position, align the chassis rails with the screw
holes at the front of the side panels (see Figure 13).
If the mounting brackets are in the front mounting position, align the chassis rails with the screw
holes at the rear of the side panels (see Figure 14).
Use M4 screws (supplied with the switch) to attach the chassis rails to the chassis.
NOTE:
Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.
Connecting the grounding cable to the chassis
CAUTION:
The primary grounding point and auxiliary grounding point 1 are located on the left side panel. If you use
one of these grounding points, you must connect the grounding cable to the grounding point before you
mount the switch in the rack.
NOTE:
• HP recommends that you use the primary grounding point or auxiliary grounding point 1 because the
grounding cable and grounding screw that come with the switch are suitable only for these two
grounding points.
• To use auxiliary grounding point 2 on the HP 5900AF-48XG-4QSFP+ switch, you must prepare a
grounding cable yourself.
To connect the grounding cable to a chassis grounding point, for example, the primary grounding point:
1.
Choose a grounding point.
2.
Unpack the grounding cable and grounding screws.
You can use the cable and screws shipped with the switch only for connecting to the primary
grounding point or auxiliary grounding point 1.
3.
Align the two-hole grounding lug at one end of the cable with the grounding holes of the
grounding point, insert the grounding screws into the holes, and tighten the screws with a
screwdriver to attach the grounding lug to the chassis, as shown in Figure 13.

Attaching the slide rails to the rack
To attach the slide rails to the rack:
1.
Identify the rack attachment position for the slide rails.
2.
Install cage nuts (user-supplied) in the mounting holes in the rack posts.
3.
Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use
screws (user supplied) to attach the slide rail to the rack, as shown in Figure 15.
4.
Repeat the preceding step to attach the other slide rail to the rack post on the other side.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.
11
Figure 15 Installing the slide rails
Mounting the switch in the rack
This task requires two people. To mount the switch in the rack:
1.
Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2.
Check that the mounting brackets and chassis rails have been securely attached to the switch
chassis.
3.
Check that the slide rails have been correctly attached to the rear rack posts.
4.
Install cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as
the slide rails.
5.
Supporting the bottom of the switch, align the chassis rails with the slide rails on the rack posts, as
shown in Figure 16. Work with another person to slide the chassis rails along the slide rails until
the mounting brackets are flush with the rack posts.
6.

Grounding the switch
WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
13
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 a switch by using a grounding strip at the installation site or the AC power cord
connected to the switch.
NOTE:
The power and grounding terminals in this section are for illustration only.
Grounding the switch with a grounding strip
WARNING!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire
main or lightning rod.
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.
To connect the grounding cable:
1.
Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the
switch chassis (see “Connecting the grounding cable to the chassis”).
2.
Remove the hex nut of a grounding post on the grounding strip.
3.
Attach the OT terminal at the other end of the grounding cable to the grounding strip through the
grounding post, and fasten the OT terminal with the removed hex nut.

NOTE:
• HP recommends that you use the primary grounding point or auxiliary grounding point 1, because the
grounding cable and grounding screw provided with the switch are applicable only to these two
grounding points.
• To use auxiliary grounding point 2 on the HP 5900AF-48XG-4QSFP+ switch, you must prepare a
grounding cable yourself. The connection method is the same as connecting to the other two grounding
points.
Grounding the switch by using the AC power cord
If the installation site has no grounding strips, you can ground an AC-powered switch through the
protective earth (PE) wire of the power cord, but must make sure:
•
The power cord has a PE terminal.
•
The ground contact in the power outlet is securely connected to the ground in the power distribution
room or on the AC transformer side.
•
The power cord is securely connected to the power outlet.
NOTE:
If the ground contact in the power outlet is not connected to the ground, report the problem and reconstruct
the grounding system.

Installing/removing a fan tray
CAUTION:
The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches require two same direction air flow fan
trays to function properly.
• Do not operate the system with only one fan tray for more than 24 hours.
• Do not operate the system without any fan tray for more than 2 minutes.
• Do not operate the system outside of the temperature range 0°C to 45°C (32°F to 113°F) degrees.
Failure to comply with these operating requirements may void the warranty.
Installing a fan tray
CAUTION:
To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently. If you
encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again.
To install a fan tray:
1.
Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2.
Unpack the fan tray and check that the fan tray model is correct.
3.
Grasp the handle of the fan tray with one hand and support the fan tray bottom with the other, and
slide the fan tray along the guide rails into the slot until the fan tray seats in the slot and has a firm
contact with the backplane (see callout 1 in Figure 20 or Figure 21).
4.
Fasten the captive screw on the fan tray with a Philips screwdriver until the fan tray is securely
attached in the chassis (see callout 2 in Figure 20 or Figure 21).

slot.
4.
Put away the removed fan tray in an antistatic bag for future use.
Installing/removing a power supply
WARNING!
In power redundancy mode, you can replace a power supply without powering off the switch but must
strictly follow the installation and procedures in Figure 22 and Figure 23 to avoid any bodily injury or
damage to the switch.
The switches do not support intermixing of AC and DC power supplies.
The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches come with both power supply slots empty
and the power filler modules as accessories.
You can install one or two power supplies for these switches as needed. For more information about the
power supplies available for the switches, see “Hot swappable power supplies.”

Figure 22 Installation procedure
Figure 23 Removal procedure
NOTE:
The HP A58x0AF 650W AC power supply and the HP A58x0AF 650W DC power supply are referred to
as the 650W AC power supply and the 650W DC power supply throughout this installation guide.
Installing a power supply
CAUTION:
• Follow the forward inertia of the power supply when inserting it into the chassis, and make sure that the
power supply has firm contact with the connectors on the backplane.
• To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If you
encounter a hard resistance while inserting the power supply, pull out the power supply and insert it
again.
• If only one power supply is installed, install a power filler module in the empty power supply slot for
good ventilation of the switch.
To install a 650W AC power supply or 650W DC power supply into the switch:
1.
Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2.
Unpack the power supply and check that the power supply model is correct.
3.
Correctly orient the power supply with the power supply slot (see Figure 24), grasp the handle of
the power supply with one hand and support its bottom with the other, and slide the power supply
slowly along the guide rails into the slot.
The slot is foolproof. If you cannot insert the power supply into the slot, re-orient the power supply
rather than use excessive force to push it in.

Setting up an IRF fabric
You can use HP IRF technology to connect and virtualize HP 5920 and 5900 switches into a large virtual
switch called an “IRF fabric” for flattened network topology, and high availability, scalability, and
manageability.
To set up IRF links between HP 5920 and 5900 series switches, use SFP+ ports or QSFP+ ports.

Connect the physical IRF ports on switches. Use SFP+ or QSFP+ transceiver
modules and fibers for long-distance connection. Use SFP+ or QSFP+ cables for
short-distance connection.
All switches except the master switch automatically reboot, and the IRF fabric is
established.
Planning IRF fabric setup
This section describes issues that an IRF fabric setup plan must cover.
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.
Plan the installation site depending on your network solution, as follows:
•
Place all IRF member switches in one rack for centralized high-density access.
•
Distribute the IRF member switches in different racks to implement the top-of-rack (ToR) access
solution for a data center.
NOTE:
• As your business grows, you can plug an HP 5920 or 5900 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 HP
5920 & 5900 Switch Series IRF Configuration Guide.
33
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.
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, the logical interfaces for the connections
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 at least one physical port 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.
The HP 5900AF-48XG-4QSFP+ switch can provide 10-GE and 40-GE IRF connections through SFP+
ports and QSFP+ ports, respectively. You can bind several SFP+ or QSFP+ ports to an IRF port for
increased bandwidth and availability.
The HP 5920AF-24XG switch can provide 10-GE IRF connections through SFP+ ports. You can bind
several SFP+ ports to an IRF port for increased bandwidth and availability.
NOTE:
• Figure 38 and Figure 39 show the topologies of an IRF fabric made up of three HP
5900AF-48XG-4QSFP+ switches that use SFP+ ports for IRF connections.
• The IRF port connections in the two figures are for illustration only, and more connection methods are
available.

Identifying physical IRF ports on the member switches
Identify the SFP+ or QSFP+ ports to be used for IRF connections on the member switches according to
your topology and connection scheme.
The HP 5920 and 5900 series switches do not have any IRF port binding restriction. You can bind any
SFP+ or QSFP+ port on the switch chassis to any IRF port.
Planning the cabling scheme
Use SFP+/QSFP+ cables or SFP+/QSFP+ transceiver modules and fibers to connect the IRF member
switches. If the IRF member switches are far away from one another, choose the SFP+/QSFP+ transceiver
modules with optical fibers. If the IRF member switches are all in one equipment room, choose
SFP+/QSFP+ cables. For more information available SFP+/QSFP+ cables and transceiver modules, see
“SFP+ port” and “QSFP+ port.”
The following subsections describe several HP recommended IRF connection schemes, and all these
schemes use a ring topology.
Connecting the IRF member switches in one rack
Use short-haul and long-haul SFP+ cables to connect the IRF member switches (four switches in this
example) in a rack as shown in Figure 40. The switches in the ring topology (see Figure 41) are in the
same order as connected in the rack.

SFP+/QSFP+ cables, and SFP+/QSFP+ transceiver modules, and optical fibers. The topology is the
same as Figure 41.

36
Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see HP 5920 & 5900 Switch Series Fundamentals Configuration Guide) to configure their member IDs,
member priorities, and IRF port bindings.
Follow these guidelines when you configure the 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. You perform
IRF port binding before or after connecting IRF physical ports depending on the software release.
•
To bind the ports on an interface card to an IRF port, you must install the interface card first. For how
to install an interface card, see HP 5920 & 5900 Switch Series Interface Cards User Guide.
•
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see HP 5920 & 5900 Switch Series IRF
Configuration Guide.
Connecting the physical IRF ports
Use SFP+/QSFP+ cables or SFP+/QSFP+ transceiver modules and fibers to connect the IRF member
switches as planned.
NOTE:
Wear an ESD-preventive wrist strap when you connect SFP+ cables or SFP+ transceiver modules and
fibers. For how to connect them, see SFP/SFP+/XFP Transceiver Modules Installation Guide and QSFP+
Transceiver Modules/Cables 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 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 HP
5920 & 5900 Switch Series Fundamentals Configuration Guide.)
4.
Check 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 Table 5.
Table 5 Display and maintain IRF configuration and running status
To do …
Use the command…
Display information about the IRF fabric
display irf
Display all members’ IRF configurations that take

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 HP 5920 & 5900 Switch Series IRF Configuration Guide.

You can use the LEDs on the power supply to identify a power supply failure. For more information about
the LEDs on a power supply, see HP A58x0AF 650W AC (JC680A) & 650W DC (JC681A) Power
Supplies User Guide.
The LEDs on the power supply are steady green (active) or blinking green (standby) while the power
supply system is correctly working. If the LEDs behave in any other way, verify the following items:
•
The switch power cord is properly connected.
•
The power source meets the requirement.
•
The operating temperature of the switch is in the normal range and the power supply has good
ventilation.
39
NOTE:
If the problem persists, contact the HP technical support for help.
To replace a hot swappable power supply, see “Installing/removing a power supply.”
Fan failure
CAUTION:
The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches require two same direction air flow fan
trays to function properly.
• Do not operate the system with only one fan tray for more than 24 hours.
• Do not operate the system without any fan tray for more than 2 minutes.
• Do not operate the system outside of the temperature range 0°C to 45°C (32°F to 113°F) degrees.
Failure to comply with these operating requirements may void the warranty.
When a fan tray has problems, the system status LED is steady red and the system outputs alarm
messages.
To replace a failed fan tray, see “Installing/removing a fan tray.”
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 displays nothing or
garbled text.
No terminal display
If the configuration terminal displays nothing when the switch is powered on, verify the following items:
•
The power supply is supplying power to the switch.
•
The console cable is properly 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:
•
Baud rate—9,600
•
Data bits—8
•
Parity—none
•
Stop bits—1
•
Flow control—none
•
