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 interface cards and power supplies, wear an ESD-preventive wrist
strap to avoid damaging the units.
Examining the installation site
The A5500 HI 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.
•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 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.

5
•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 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.
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.
Table 3 Harmful gas limits in the equipment room
Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
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.

6
Laser safety
The A5500 HI 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.
Installation tools
•Flat-blade screwdriver
•Phillips screwdriver
•Long-nose pliers
•Diagonal cutting pliers
•ESD-preventive wrist strap
•Blow dryer
All these installation tools are user supplied.

Installing the switch in a 19-inch rack
Every A5500 HI switch comes with a pair of mounting brackets (see Figure 7) for rack mounting.
Figure 6 Rack-mounting procedure
Figure 7 Mounting bracket
(1) Hole for attaching to a rack (by using an M6 screw)
(2) Hole for attaching to the switch chassis
Prerequisites
If you are installing an LSP5GP8P0 (JG314A) interface card, make sure the rack depth is 800 mm (31.50
in) or 1000 mm (39.37 in). This card adds 69.75 mm (2.75 in) to the chassis depth (see Figure 24) in
addition to the clearance required for installing transceiver modules and cables.
Attaching the mounting brackets to the chassis
To attach the mounting brackets to the chassis:
1. Identify the front mounting position (see Figure 8) and rear mounting position (see Figure 9) on the
two sides of the chassis.
2. Align the round holes in the wide flange of one front mounting bracket with the screw holes in the
front or rear mounting position on one side of the chassis
3. Use M4 screws (supplied with the switch) to attach the mounting bracket to the chassis.
4. Repeat the preceding two steps to attach the other mounting bracket to the other side of the
chassis.
NOTE:
The screw holes in the figures in this section are for illustration only.

Rack-mounting the switch
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 have been securely attached to the switch chassis.
3. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
4. One person holds the switch chassis and aligns the mounting brackets with the mounting holes in
the rack posts, and the other person attaches the mounting brackets with screws (user-supplied) to
the rack.
5. Check that the switch chassis is horizontal and tighten the screws.

10

Mounting the switch on a workbench
IMPORTANT:
•Ensure good ventilation and 10 cm (3.9 in) of clearance around the chassis for heat dissipation.
•Avoid placing heavy objects on the switch.
To mount the switch on a workbench:
1. Check that the workbench is sturdy and well grounded.
2. Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth.
3. Attach the rubber feet to the four round holes in the chassis bottom.
4. Place the switch with upside up on the workbench.

11
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 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
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.
To connect the rear grounding point to a grounding strip:
1. Remove the grounding screw from the rear panel of the switch chassis.
2. Attach the grounding screw to the OT terminal of the grounding cable.
3. Use a screwdriver to fasten the grounding screw into the grounding screw hole.
IMPORTANT:
Orient the grounding cable as shown in Figure 11 so you can easily install or remove power supplies.

through the black insulation covering into the end of the OT terminal supplied with the switch.
8. Secure the metal part of the cable to the OT 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.
9. Connect the OT terminal to the grounding post of the grounding strip, and fasten it with the
removed hex nut.

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. Make sure that:

14
•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
g
round, 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
W
ARNING!
In power redundancy mode, you can replace a power supply without powerin
g
off the switch but mus
t
strictly follow the installation and procedures in Figure 16 and Figure 17 to avoid any bodily injury o
r
damage to the switch.

Figure 17 Removal procedure
The installation and removal procedures for the PSR150-A and PSR150-D power supplies are the same.
This document uses the PSR150-A as an example.
Installing a power supply
CAUTION:
To prevent damage to the power supply or the connectors on the backplane, 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.
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.
3. Unpack the power supply and check that the power supply model is correct.
4. Correctly orient the power supply with the power supply slot (use the letters on the power supply
faceplate for orientation), 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 18).
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 18). If the captive screw cannot be tightly fastened,
check the installation of the power supply.
NOTE:
If you install only one power supply, install the filler panel over the empty power supply slot for
g
ood
v
entilation.
