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 5500 EI and 5500 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 "Environmental specifications."

2

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 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.

H2S 0.006

NH3 0.05

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 5500 EI and 5500 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

may hurt your eyes.

• Avoid placing heavy objects on the switch.

Grounding the switch

13

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.

W

ARNING!

Connect the

g

rounding cable to the grounding system in the equipment room. Do not connect it to a fire

main or lightning rod.

CAUTION:

For the 5500-24G-SFP EI (2 slots) and 5500-24G-SFP EI TAA (2 slots) switches, follow the direction
shown in Figure 11 to

connect the grounding cable to avoid affecting the installation and removal of the

power supply.

To connect the grounding cable, for example, to an HP 5500-48G 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. 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.

7. 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.

8. Attach the ring terminal or the ring to the grounding strip through the grounding post, and fasten

it with the removed hex nut, as shown in Figure 13.

Grounding the switch with a grounding conductor buried in the
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.

Grounding the switch by using the AC power cord

If the installation site has no grounding strips or earth ground, you ground an AC-powered switch through
the 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

g

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

t

the grounding system.

NOTE:

To guarantee the grounding effect, use the grounding cable provided with the switch to connect to the
grounding strip in the equipment room as long as possible.

Installing/removing a power supply

This section applies only to the 5500-24G-SFP EI (2 slots) and 5500-24G-SFP EI TAA (2 slots) switches.

This section uses a PSR150-A power supply as an example to describe the installation and removal of
power supplies.

Installing a power supply

17

CAUTION:

• To prevent dama

g

e to the power supply or the connector on the backplane of the powered device, inser

t

the power supply gently. If you encounter a hard resistance while inserting the power supply, pull out the
power supply and then insert it again.

• If the captive screw cannot be tightly secured, verify the installation of the power supply.

To install a power supply:

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

grounded.

2. If the power supply slot is covered by a filler panel, remove the filler panel first.

Put away the filler panel for future use.

3. Unpack the power supply and verify that the power supply model is correct.

4. Correctly orient the power supply with the power supply slot, 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 (see callout 1 in Figure 16).

The sl

ot 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.

5. Fasten the captive screws on the power supply with a Philips screwdriver to secure the power

supply in the chassis (see callout 2 in Figure 16).

Figure 16 Installing a po

wer supply

NOTE:

If you install only one power supply, install the filler panel over the empty power supply slot for good

Accessing the switch for the first time

Setting up the configuration environment

The first time you access the switch you must use a console cable to connect a console terminal, for
example, a PC, to the console port on the switch.

Figure 24 Connecting the console port to a terminal

Connecting the console cable

Console cable

A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting
to the console port of the switch, and a DB-9 female connector at the other end for connecting to the
serial port on the console terminal.

Figure 25 Console cable

Connection procedure

To connect a terminal, for example, a PC, to the switch:

1. Plug the DB-9 female connector of the console cable to the serial port of the PC.

25

2. Connect the RJ-45 connector to the console port of the switch.

NOTE:

• Identify the mark on the console port and make sure you are connecting to the correct port.

• The serial ports on PCs do not support hot swapping. If the switch has been powered on, connect the

console cable to the PC before connecting to the switch, and when you disconnect the cable, first
disconnect from the switch.

Setting terminal parameters

To configure and manage the switch, you must run a terminal emulator program on the console terminal.

The following are the required terminal settings:

• Bits per second—9,600

• Data bits—8

• Parity—None

• Stop bits—1

• Flow control—None

• Emulation—VT100

To set terminal parameters, for example, on a Windows XP HyperTerminal:

1. Select Start > All Programs > Accessories > Communications > HyperTerminal.

The Connection Description dialog box appears.

2. Enter the name of the new connection in the Name field and click OK.

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 5500 EI
switches or 5500 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:

A

n IRF fabric cannot have both 5500 EI and 5500 SI switches.

IRF fabric setup flowchart

Figure 31 IRF fabric setup flowchart

To set up an IRF fabric:

30

Step Description

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 in a 19-inch rack" a

nd "Mounting the switch on a

workbench."

3. Connect the grounding

cable, power supplies
(optional), and power
cords

See "Grounding the switch" a

nd "Connecting the power cord."

If an HP 5500-24G-SFP EI (2 slots) or 5500-24G-SFP EI TAA (2 slots) switch
is used, also see "Installing/removing a power supply."

4. Power on the switches

N/A

5. Install interface cards

See "Installing/removing an interface card."

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.

NOTE:

A

s your business grows, you can plug a switch into an IRF fabric to increase the switching capacity withou

t

any topology change or replacement.

Identifying the master switch and planning IRF member IDs

Determine which switch you want t o use as th e master for m anaging 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

H

P

5500 EI & 5500 SI Switch Series IRF Configuration Guide

.

31

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. 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 32 an

d Figure 33 show the topologies of an IRF fabric made up of three 5500 EI or 5500 SI

switches.

• The IRF port connections in the two fi

g

ures are for illustration only, and more connection methods are

available.

32

Identifying physical IRF ports on the member switches

Only the 10-GE ports on the IRF-capable interface cards listed in "Interface cards" can provide IRF
connections for the 5500 EI and 5500 SI switches. To use the IRF feature, you must order the cards
separately.

IMPORTANT:

A

ll the switches in a ring topology and the non-edge switches in a daisy chain topology must have at leas

t

one two-port interface card or two one-port interface cards.

Planning the cabling scheme

When you plan the cabling scheme, follow these guidelines:

• Ports assigned to the same IRF port must be on the same interface card.

• 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

ca

rds" and "SFP/SFP+/XFP transceiver modules and SFP+/CX4 cables."

• If 2-port interface cards are used and the IRF links are not aggregate:

{ 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 34.

Figure 34 Use 2-port interface cards to set up singl

e-link IRF connection

• If 2-port interface cards are used and IRF links are aggregate:

{

Connect the interface card MOD 1 on one switch to 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 35. F

or example, you can connect the left port on one interface card to the left or right

port on the other interface card.

• If both of the neighboring 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 36).

• 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 36.)

{ 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.

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 5500 EI & 5500 SI 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.

• 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.

34

For more information about configuring basic IRF settings, see HP 5500 EI & 5500 SI Switch Series IRF
Configuration Guide.

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

When you are finished configuring basic IRF settings and connecting IRF ports, follow these steps to
verify the basic functionality of the IRF fabric:

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 5500 EI & 5500 SI Switch Series Fundamentals Configuration Guide.

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.

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

Maintenance and troubleshooting

Power supply failure

Built-in power supply failure

Except the 550 0-24G-SFP E I (2 sl ots ) and 5500-24G-SFP EI TAA (2 slots) switches, all 5500 EI and 5500
SI switches use built-in power supplies and support three input modes: AC input, RPS DC input, and
concurrent AC and RPS DC inputs.

You can look at the system status LED and the RPS status LED on the front panel of the switch to identify
a power failure. For more information, see "LEDs."

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.

36

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:

{ TThe 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.

Hot swappable power supply failure

This section applies to the 5500-24G-SFP EI (2 slots) and 5500-24G-SFP EI TAA (2 slots) switches.

You can look at the PWR1 or PWR2 LED (see Table 13)

on the front panel of an HP 5500-24G-SFP EI (2
slots) or 5500-24G-SFP EI TAA (2 slots) switch and the LEDs on the power supply to identify a power
supply failure.

If the power supply system is correctly working, the power supply LEDs are steady green. If the LEDs
behave in any other way (see Table 13)

, verify the following items:

• The power cord is correctly connected.

• The power supply 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 your local sales agent or service engineer.

To replace a hot swappable power supply, see "Installing/removing a power supply."

Fan failure

You can look at the system status LED and the seven-segment LED of the switch to identify a fan failure.
If both LEDs are behaving as described in Table 6,

a fan failure occurs.

Table 6 LED behaviors that identify a fan failure

The LED flashes F for fan failure.

37

The 5500 EI and 5500 SI 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.

• 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:

• Baud rate—9,600

• Data bits—8

• Parity—none

• Stop bits—1

• Flow control—none

• Emulation—VT100
