Preparing for installation
H3C S7500X Switch Series includes the following models:
•S7503X.
•S7506X-PoE.
•S7510X-PoE.
Safety recommendations
To avoid possible bodily injury and equipment damage, read the safety recommendations in this
chapter carefully before installing the switch. The recommendations do not cover every possible
hazardous condition.
General safety recommendations
•Keep the chassis clean and dust-free.
•Do not place the switch on a moist area and avoid liquid flowing into the switch.
•Make sure the ground is dry and flat and you have adopted anti-slip measures.
•Keep the chassis and installation tools away from walk areas.
•Do not wear loose clothing, jewelry (for example, necklace) or any other things that could get
caught in the chassis when you install and maintain the switch.
Electricity safety
•Clear the work area of possible hazards, such as ungrounded power extension cables, missing
safety grounds, and moist floors.
•Locate the emergency power-off switch in the room before installation. Shut the power off at
once in case accident occurs.
•Remove all the external cables (including power cords) before moving the chassis.
•Do not work alone when the switch has power.
•Always verify that the power has been disconnected.
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:
•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.

2
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 "Installing 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 "Installing FRUs."
•Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
•Put cards in an ESD bag.
Laser safety
WARNING!
Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the switch is operating.
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.
Table 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)

3
Humidity
Maintain appropriate humidity in your equipment room, as described in Table 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 2 Humidity requirements
Humidity Range
Operating humidity (noncondensing) 5% RH to 95% RH
Storage humidity (noncondensing) 5% RH to 95% RH
Cleanliness
Mechanically active substances 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 3 Mechanically active substance concentration limit in the equipment room
Substance Particle diameter Concentration limit
Dust particles ≥5 µm

Dust
(sedimentation) 75 µm to 150 µm ≤1.5 mg/(m2h)
Sand ≥150 µm ≤30 mg/m3
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion
and premature aging of components, as shown in Tabl e 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.

4
•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 "Installing 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. It also includes PoE power
consumption if the switch provides PoE power. For more information about the total power
consumption of the switch, see "Appendix A Chassis views and technical 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 "Appendix B FRUs and compatibility matrixes."
3. Verify that the power supply system on the installation site is stable and satisfies the input
requirements of the power modules.
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.

IMPORTANT:
To ensure the stability of the rack, mount the switch at the lowest possible position. To mount
multiple switches on the rack, mount the heaviest switch at the bottom of the rack.
Attaching slide rails and cage nuts to the rack
Installing slide rails
Before installing the switch in a rack, attach slide rails to the rack. If the rack has slide rails, skip this
section. Verify that the slide rails can support theweight of the switch beforeattaching it to the switch.
For the weight of the switch, see "AppendixAChassis views and technical specifications." As a best
practice, order the H3C Slide RailAccessories,500mm-800mm (LSTM2KSGD0) for the switch.
Determine the installation position of the switch in the rack as required. For the dimensions of the
switch, see "AppendixA Chassis views and technical specifications."
The slide rail installation procedure varies by rack type The following installation procedure is for
your reference only.
To install a slide rail:
