Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.
•
Before cleaning the switch, remove 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 good 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 a removable component such as a power supply or fan tray, wear an ESD wrist
strap and make sure it makes good skin contact and is reliably grounded.
Examining the installation site
The switch must be used indoors. Mount your switch in a rack and verify the following items:
•
Adequate clearance is reserved at the air inlet and outlet 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 flowingout of the bottom
device from entering the top device.
•
The rack is sturdy enough to support the switch and its accessories.
•
The rack is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.

1-2
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
•
Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•
Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose 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 H3C S6116
Ultra-Low Latency Switch Series Hardware Information and Specifications.
Cleanliness
Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in
poor contact of metal connectors and contact points. This might shorten the device's lifetime and
even cause device failure in the worst case. Table1-2 describes the switch requirement for
cleanliness.
Table1-2 Switch requirement for cleanliness
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 1.8 × 107particles/m3
To maintain cleanliness in the equipment room, follow these guidelines:
•
Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the
equipment room.
•
Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips.
Use screen doors and window screens for doors and windows open to the outside and make
sure the external windows are air tight.
•
Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does
not produce powders.
•
Clean the equipment room regularly and clean the air filters of the rack each month.
•
Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD
clothing and shoe covers clean, and change them frequently.
Corrosive gas limit
Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive
gases do not exceed the concentration limits as shown inTable1-3.
Table1-3 Corrosive gas concentration limits
Gas Average concentration (mg/m3) Maximum concentration (mg/m3)
SO20.3 1.0
H2S 0.1 0.5
Cl20.1 0.3
HCI 0.1 0.5
HF 0.01 0.03

1-3
Gas Average concentration (mg/m3) Maximum concentration (mg/m3)
NH31.0 3.0
O30.05 0.1
NOX0.5 1.0
CAUTION:
As a best practice, control the
corrosive gas concentrations in the equipment room at their
average
values
. Make sure the corrosive gas concentrations do not exceed 30 minutes per day at their
maximum values.
To control corrosive gases, use the following guidelines:
•
As a best practice, do not build the equipment room in a place with a high concentration of
corrosive gases.
•
Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines
and keep it far away from these pipelines. The air inlet of the equipment room must be away
from such pollution sources.
•
Use environmentally friendly materials to decorate the equipment room. Avoid using organic
materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons,
rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.
•
Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment
room with the device. Make sure the exhausted air of the engines will not flow into the
equipment room or towards the air inlet of the air conditioners.
•
Place batteries separately. Do not place them in the same room with the device.
•
Employ a professional company to monitor and control corrosive gases in the equipment room
regularly.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
•
A conduction pattern of capacitance coupling.
•
Inductance coupling.
•
Electromagnetic wave radiation.
•
Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
•
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.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.

Rack-mounting the switch by using front and rear mounting
brackets
Attaching the front mounting brackets and shoulder screws to the switch
The switch provides two installation positions for front mounting brackets. One is near the port side
and the other is near the power supply side. Choose the installation position for the front mounting
brackets as required. The screw (mounting bracket screws and shoulder screws) installation method
differs slightly for installing the front mounting brackets at the power supply side or port side.
To attach the front mounting brackets and shoulder screws to the switch:
1. Align the holes in the wide flange of one front mounting bracket with the screw holes in a side
panel of the chassis. See Figure2-9 and Figure2-10.
2. Use M4 screws (supplied with the switch) to attach the mounting bracket to the chassis.
As a best practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten the M4 screws.
3. Repeat the preceding two steps to attach the other mounting bracket to the chassis.
4. Unpack the shoulder screws and attach them to the chassis. As a best practice, use a torque of
12 kgf-cm (1.18 Nm) to fasten the shoulder screws.
If you install the front mounting brackets at the port side, two installation positions are available
for the shoulder screw (red marked in Figure2-9).
If you install the front mounting brackets at the power supply side, one installation position is
available for the shoulder screw (red marked in Figure2-10.).

IMPORTANT:
M4 screws are used to secure the mounting brackets and chassis rails to the switch.
As a best
practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten M4 screws.
To attach the mounting brackets and chassis rails to the chassis:
1. Place the wide flange of a front mounting bracket against a side panel of the chassis and align
the round holes in the wide flange of the front mounting bracket with the screw holes in the side
panel. Then use M4 screws (provided) to attach the front mounting bracket to the chassis.
To install the front mounting brackets at the port side, see Figure2-16, Figure2-17, and
Figure2-18.
To install the front mounting brackets at the power supply side, see Figure2-19,Figure2-20,
and Figure2-21.
2. Determine the chassis rail installation position based on the front mounting bracket installation
position.
3. Place the chassis rail against the side panel of the chassis and align the installation holes in the
chassis rail with rail mounting holes in the chassis. Then use M4 screws (provided) to attach the
chassis rail to the chassis.
For installation of chassis rails of rack mounting rail kit A (long slide rails), see Figure2-16
and Figure2-19.
The chassis rails of rack mounting rail kit B (super-short slide rails) support narrow-spacing
installation and wide-spacing installation. Select narrow-spacing (as shown in Figure2-17
and Figure2-20) or wide-spacing (as shown in Figure2-18 and Figure2-21) installation
based on the distance between the front and rear rack posts.
4. Follow the same procedure to attach another mounting bracket and chassis rail to the opposite
chassis side.

6 screws and cage nuts are used to attach the slide rails to the rack. P
repare M6 screws and cage
nuts yourself. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
Before mounting the switch in the rack, you must attach slide rails to the rack.
The installation procedure is the same for different types of slide rails. The following procedure
attaches 1U long slide rails to the rack.
To attach the slide rails to the rack:
1. Identify the slide rail installation position on the rack based on the switch installation position.
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 a rear rack post, and then use M6
screws (user-supplied) to attach the slide rail to the rack, as shown in Figure2-22.

2-18
4. Attach the other slide rail to the rear rack post on the opposite side.
Make sure the two slide rails are at the same height and can slide into the chassis rails
smoothly.
Figure2-22 Installing the 1U long slide rails
Mounting the switch in the rack
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Verify that the front 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. Attach cage nuts (user-supplied) to the front rack posts and make sure they are at the same
level as the slide rails.
5. One person performs the following operations:
a. Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack
posts.
b. Pushes the switch slowly for the slide rails to slide into the chassis rails smoothly until the
mounting brackets are flush against the front rack posts.
−For long slide rails of rack mounting rail kit A and slide rails of rack mounting rail kit C,
make sure the front ends of the slide rails reach out of the chassis rails.
