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 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 5920 and 5900 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 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.

8

• 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

spec

ifications."

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 2 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:

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 3.

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 5920 and 5900 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

may hurt your eyes.

Attaching the mounting brackets and chassis rails to the chassis

To attach the mounting brackets and chassis rails to the switch chassis:

1. Align the mounting brackets with the screw holes in the rear mounting position or front mounting

position. See Figure 20 and Figure 21.

2. Use M4 screws (supplied with the switch) to attach the mounting brackets to the chassis.

3. Align the chassis rails with the rail mounting holes in the chassis:

{ 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 20.

{ 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 21.

4. 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.

14

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+, 5900AF-48XG-4QSFP+ TAA,

5900AF-48XGT-4QSFP+, and 5900AF-48G-4XG-2QSFP+ switches, 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 20.

Figure 21 Attaching the front mounting brackets/chassis rails to the chassis

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 22.

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.

Figure 22 Installing the slide rails

Mounting the switch in the rack

This task requires two people. To mount the switch in the rack:

16

1.

Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.

2. Verify that the mounting brackets and chassis rails have been securely attached to the switch

chassis.

3. Verify 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 23. Work with another person to slid

e the chassis rails along the slide rails until

the mounting brackets are flush with the rack posts.

6. Use screws (user-supplied) to attach the mounting brackets to the rack, as shown in Figure 24.

To secure the switch in the rack, make sure the front ends of the slide rails reach out of the chassis
rails.

Grounding the switch

W

ARNING!

Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.

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

W

ARNING!

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.

18

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 ring terminal at the other end of the grounding cable to the grounding strip through the

grounding post, and fasten the ring 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+, 5900AF-48XG-4QSFP+ TAA,

5900AF-48XGT-4QSFP+, and 5900AF-48G-4XG-2QSFP+ switches, 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.

19

NOTE:

If the

g

round contact in the power outlet is not connected to the ground, report the problem and reconstruc

t

the grounding system.

ARNING!

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 29 and Figure 30 to avoid a

ny bodily injury or

damage to the switch.

The switches do not support intermixing of AC and DC power supplies.

The HP 5920 and 5900 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."

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 switches, use SFP+ ports, 1/10-GE Ethernet ports, or
QSFP+ ports.

See HP 5920 & 5900 Switch Series IRF Configuration Guide.

6. Connect the physical

IRF 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:

A

s 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 wa nt to use as the master for manag ing all m ember swi tch e s in the I RF 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.

33

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

H

P

5920 & 5900 Switch Series IRF Configuration Guide

.

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+, 5900AF-48XG-4QSFP+ TAA, and 5900AF-48G-4XG-2QSFP+
switches 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 5900AF-48XGT-4QSFP+ switch can provide 10-GE and 40-GE IRF connections through
1/10-GE Ethernet ports or QSFP+ ports. You can bind several 1/10-GE Ethernet ports or QSFP+ ports
to an IRF port for increased bandwidth and availability.

The HP 5920AF-24XG, and 5920AF-24XG TAA switches 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 45 an

d Figure 46 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 fi

g

ures are for illustration only, and more connection methods are

available.

Figure 46 IRF fabric in ring topology

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.

All the SFP+ and QSFP+ ports on the HP 5900AF-48XG-4QSFP+, 5900AF-48XG-4QSFP+ TAA, and
5900AF-48G-4XG-2QSFP+ switches, all the 1/10-GE Ethernet ports and QSFP+ ports on the HP
5900AF-48XGT-4QSFP+ switch, and all the SFP+ ports on the HP 5920AF-24XG and 5920AF-24XG
TAA switches can be used for IRF connections.

Follow these guidelines when you identify 1/10-GE Ethernet ports and SFP+ ports to be used for IRF
connections:

• On the HP 5920AF-24XG, 5920AF-24XG TAA, 5900AF-48XG-4QSFP+, and

5900AF-48XG-4QSFP+ TAA switches, the SFP+ ports are grouped by port number in ascending
order, starting from one. Every four SFP+ ports form one group.

• On the HP 5900AF-48G-4XG-2QSFP+ switch, SFP+ ports numbered 49, 50, 51, and 52 form one

group.

• On the HP 5900AF-48XGT-4QSFP+ switch, the 1/10-GE Ethernet ports are grouped by port

number in ascending order, starting from one. Every four 1/10-GE Ethernet ports form one group.

• All 1/10-GE Ethernet ports and SFP+ ports in the same group must be used for the same purpose

(physical IRF ports or service ports, but not both).

A common practice is to use one 1/10-GE Ethernet port or SFP+ port group for IRF connections, and
bind every two 1/10-GE Ethernet port or SFP+ ports in the group to an IRF port for increased bandwidth
and availability.

Planning the cabling scheme

For the HP 5920AF-24XG, 5920AF-24XG TAA, 5900AF-48XG-4QSFP+, 5900AF-48XG-4QSFP+ TAA,
and 5900AF-48G-4XG-2QSFP+ switches, use SFP+/QSFP+ cables or SFP+/QSFP+ transceiver
modules and fibers to connect the IRF member switches. For the HP 5900AF-48XGT-4QSFP+ switches,
use twisted pair cables, QSFP+ cables, or 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
twisted pair/SFP+/QSFP+ cables. For more information about available SFP+/QSFP+ cables and
transceiver modules, see "SFP+ port" and "QSFP+ port."

T

he 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 47. T

he switches in the ring topology (as shown in Figure 48) are

in the same order as connected in the rack.

Figure 48 IRF fabric topology

Connecting the IRF member switches in a ToR solution

You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.

Figure 49 sho

ws an example for connecting four top of rack IRF member switches by using SFP+/QSFP+

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

48.

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member switch
to configure their member IDs, member priorities, and IRF port bindings. For more information, see HP
5920 & 5900 Switch Series Fundamentals Configuration Guide.

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.

• 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:

W

ear 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 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 4.

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

.

Maintenance and troubleshooting

Power supply failure

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.

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:

Every HP 5920 and 5900 switch requires two same direction air flow fan trays to function properly.

• Do not operate the system with one failed fan tray for more than 24 hours.

• Do not remove the failed fan tray until you are ready for replacing it.

• 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.

39

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

• Emulation—VT100

Appendix D Cooling system

The cooling system of the HP 5920 and 5900 switches comprises the ventilation holes in the chassis, fan
trays, and built-in fans of hot swappable power supplies. To guarantee that this cooling system can
effectively work, you must consider the site ventilation design when you plan the installation site for the
switches.

HP 5920AF-24XG cooling system

The fan trays in the HP 5920AF-24XG and 5920AF-24XG TAA switches must be the same type:
LSVM1FANSC or LSVM1FANSCB.

• When LSVM1FANSC fan trays are used, cool air flows in through the air vents in the fan tray panel

and the power supply panels, circulates through the chassis and the power supplies, and exhausts
at the network port side, as shown in Figure 55.

• W

hen LSVM1FANSCB fan trays are used, cool air flows in through the air vents in the network
port-side panel and the power supply panels, circulates through the chassis and the power supplies,
and exhausts through the air vents in the fan tray panels, as shown in Figure 56.
