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 interface cards, power modules, and fan trays, wear an
ESD-preventive wrist strap to avoid damaging the units.
Examining the installation site
The S5120-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 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 proper 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.

7
•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 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.

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 S5120-HI switches are Class 1 laser devices.

ARNING!
Do not stare into any fiber port when the switch has power. The laser li

ht emitted from the optical fiber
may hurt your eyes.
Installation tools
•Flat-blade screwdriver
•Phillips screwdriver
•Long-nose pliers
•Diagonal cutting pliers
•Marking pen
•ESD-preventive wrist strap

Installing the switch
CAUTION:
Keep the tamper-proof seal on a mountin
g
screw on the chassis cover intact, and if you want to open the
chassis, contact H3C for permission. Otherwise, H3C shall not be liable for any consequence.

Installing the switch in a 19-inch rack
You can install an S5120-HI switch in a 19-inch rack by using one of the following methods:
•Use the front mounting brackets. Figure 9 shows the mounting procedure diagram.
•Use the front and rear mounting brackets. Figure 10 shows the mounting procedure diagram.
•Use the front mounting brackets and rack mounting rail assemblies. Figure 11shows the mounting
procedure diagram.
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 mounting brackets.

Rack-mounting by using front
mounting brackets
•Only applicable to the S5120-34C-HI and S5120-58C-HI switches.
•Install the front mounting brackets in the port-side or power-side mounting
position as needed.
•Use the rear grounding point to ground the chassis.
•If you are installing an LSP5GP8P0 interface card, make sure the rack
depth is 800 mm (31.50 in) or 1000 mm (39.37 in). The LSP5GP8P0 card
adds 69.75 mm (2.75 in) to the chassis depth (see Figure 44) in addition
to the clearance required for installing transceiver modules and cables.
Rack-mounting by using front
and rear mounting brackets
•Only applicable to the S5120-28SC-HI and S5120-52SC-HI switches.
•Rack requirement: Front-to-back rack depth must be within 389 mm (15.32
in) to 555 mm (21.85 in).
•Install the front mounting brackets in the port-side mounting position and
the load bearing screws in the power-side mounting position.
•Use the rear grounding point to ground the chassis.
•H3C recommends this installation method for enterprise network
deployment.
