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
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.

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.

NOTE:
If a rack shelf is available, you can put the switch on the rack shelf, slide the switch to an appropriate
location, and attach the switch to the rack with the mounting brackets.
Attaching the mounting brackets, chassis rails, and grounding
cable to the chassis
Each of the HP 5920 and 5900 switches has one front mounting position (near the network ports) and
one rear mounting position (near the power supplies).

12
Each of the HP 5920AF-24XG and 5920AF-24XG TAA switches has one primary grounding point (with
a grounding sign) and one auxiliary grounding point, and each of the HP 5900AF-48XG-4QSFP+,
5900AF-48XG-4QSFP+ TAA, 5900AF-48XGT-4QSFP+, and 5900AF-48G-4XG-2QSFP+ switches 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.

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.
1234 5

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.

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 slide 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.
