Handling safety
CAUTION:
•
When moving the switch, hold the handles at both sides of the chassis.
•
Do not hold the handle of a fan tray, a power module, or the
back cover of the chassis, or the air
vents of the chassis to move the switch. Any attempt to carry the switch with these parts might
cause equipment damage or even bodily injury.
To move the switch:

1-2
•
Remove all the external cables (including the power cords) before moving the chassis.
•
Use a minimum of two people to move the switch, and use a mechanical lift if necessary.
•
Move the switch carefully.
ESD prevention
To prevent the electric component from being damaged by the electrostatic discharge (ESD), adhere
to the following requirements:
•
Ground the switch correctly. For how to ground your switch, see "Grounding the switch."
•
Always wear an ESD wrist strap and make sure it is reliably grounded when installing pluggable
modules. For how to use an ESD wrist strap, see "Attaching an ESD wrist strap."
•
Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
•
Put cards in an ESD bag.
Laser safety
WARNING
!
Do not stare into any
open apertures of operating transceiver modules or optical fiber connectors.
The laser light emitted from these apertures might hurt your eyes.
The switch is a Class 1 laser product.
Examining the installation site
The switch can only be used indoors. To ensure correct operation and long service life of your switch,
the installation site must meet the requirements in this section.
Weight support
Evaluate the floor loading as compared to the actual weight of the switch and its accessories (such
as rack, chassis, cards, and power modules, and make sure the floor can support the weight of the
rack and the switch chassis.
IMPORTANT:
When evaluating the floor loading, consider switch capacity expansion (for example, installing a new
card) in the future.
Temperature
CAUTION:
If condensation appears
on the switch when you move it to a high-
temperature environment, dry the
switch before powering it on to avoid short circuits.
To ensure the correct operation of the switch, ensure that the room temperature meets the
requirements described in Table 1-1.

1-3
Table 1-1 Temperature requirements
Temperature Range
Operating temperature 0°C to 45°C (32°F to 113°F)
Storage temperature –40°C to +70°C (–40°F to +158°F)
Humidity
Maintain appropriate humidity in your equipment room, as described in Table 1-2.
•
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 bring problems
including loose mounting screws and circuit failure.
Table 1-2 Humidity requirements
Humidity Range
Operating humidity (noncondensing) 5% RH to 95% RH
Storage humidity (noncondensing) 5% RH to 95% RH
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points. In the worst case, electrostatic adsorption can cause
communication failure.
Table 1-1 Dust concentration limits in the equipment room
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 1.8 × 107particles/m3
Corrosive gases can accelerate corrosion and aging of components. Make sure the corrosive gases
in the equipment room do not exceed the concentration limits as shown in Table 1-2.

1-4
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, perform the following tasks:
•
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 to make sure the EMI levels do not exceed the compliant range.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•
To prevent signal ports from getting damaged by over-voltage or overcurrent caused by
lightning strikes, route interface cables only indoors.
Grounding
Using a good grounding system to protect your switch against lightning shocks, interferences, and
ESD is essential to the operating reliability of your switch. Make sure the resistance between the
chassis and the ground is less than 1 ohm. For more information about the grounding methods for
the switch, see "Grounding the switch."
Power supply
To ensure that the switch has a good power supply system, implement power planning as follows:
1. Calculate the total power consumption
The total power consumption of a switch is determined mainly by its configurations including
types and quantities of cards and fan tray power consumption. For more information about the
total power consumption of the switch, see H3C S7500X-G Switch Series Hardware
Information and Specifications.
2. Select power modules according to the total power consumption
To ensure correct operation of the switch, make sure the maximum output power of the power
module that supplies power to the switch is higher than the total power consumption of the
switch. After determining the total power consumption of the switch, you can select appropriate
power modules according to the total power consumption. For more information about the
optional power module models, see H3C S7500X-G Switch Series Hardware Information and
Specifications.
3. Verify that the power supply system on the installation site satisfies the input requirements of
the power modules and parameters such as rated voltage.
Cooling
For adequate heat dissipation, plan the installation site according to the airflow of your switch, and
adhere to the following requirements:
•
Leave a clearance of a minimum of 10 cm (3.94 in) around the air inlet and outlet vents.
•
The rack for installing the switch has a good cooling system.
•
The installation site has a good cooling system.

F/L Front end of the left slide rail Mount this end to the front left rack post.
F/R Front end of the right slide rail Mount this end to the front right rack post.
2. Mark the position on the rack for installing the slide rail.
Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes on a rack post, as shown in Figure 2-3.
Each rack post requires six screws to secure the slide rail. You only need to mark the
uppermost square hole and lowermost square hole for installation.
Mark the square holes at the same height on the other three rack posts.
NOTE:
One rack unit has three holes, the middle of which is an auxiliary installation hole, and the other
two are standard installation holes. You can distinguish them by the space between each two
holes. The space between a standard installation hole and an auxiliary installation hole is larger
than the space between two adjacent standard installation holes.
