Preparing for installation
Safety recommendations
To avoid possible bodily injury and equipment damage, read the safety recommendations in this chapter
carefully before installing an H3C S7508E-X 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.
•Unplug all the external cables (including power cables) before moving the chassis.
•Do not work alone when the switch has power.
•Always check that the power has been disconnected.
Handling safety
CAUTION:
•When moving the switch, hold the handles on the chassis.
•Do not hold the handle of the fan tray, power module, or back cover of the chassis, or the air vents of
chassis. Any attempt to carry the switch with these parts may cause equipment dama
g
e or even bodil
y
injury.
To move an H3C S7508E-X switch, follow these steps:
•Remove all the external cables (including the power cables) before moving the chassis.
•Use at least 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 well grounded when installing field replaceable
units (FRUs). For how to use an ESD wrist strap, see "Installing modules."

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. For more information, see "Appendix A Technical specifications."
Temperature requirements
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 normal operation of the switch, ensure that the room temperature meets the requirements
described in Table 1.

Humidity requirements
Maintain appropriate humidity in your equipment room, as described in Table 2.
•Lasting high relative humidity tends to cause poor insulation, electricity creepage, mechanical
property change of materials, and corrosion of metal parts.
•Lasting low relative humidity is likely to result in loose screws due to washer contraction, and even
electrostatic discharge (ESD), which causes the circuits to fail.

Cleanness requirements
Maintain appropriate cleanness in your equipment room.
•Dust is a hazard to the operating safety of your switch. 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 3 shows the dust concentration limit in the equipment room.
•The equipment room should meet strict limits on salts, acids and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 4.

EMI requirements
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 grounding system) coupling. To
prevent EMI, perform the following steps:
•Take measures against interference from the power grid.
•Do not use the switch together with the grounding equipment or lightning-prevention equipment of
power equipment, and keep the switch far away from them.
•Keep the switch far away from high-power radio launchers, radars, and equipment with high
frequency or high current.
•Use electromagnetic shielding when necessary.
Grounding requirements
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 of the S7508E-X
Switch, see "Installing the switch."
Power supply requirements
Perform the following steps to satisfy the power supply requirements of the S7508E-X Switch:
1. Calculate the system power consumption
The system power consumption of an S7508E-X switch depends on the card type and quantity,
and fan tray power consumption. For more information about the system power consumption of the
S7508E-X Switch, see "Appendix A Technical specifications."
2. Select power modules according to the system 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 system power consumption of the switch.
After determining the system power consumption of the switch, you can select appropriate number
of power modules according to the power consumption requirement of your switch. For more
information, see "Appendix B FRUs and compatibility matrixes."
3. Check that the power supply system on the installation site satisfies the input requirements of the
power modules and parameters such as rated voltage.
Cooling requirements
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 at least 10 cm (3.94 in) around the air intake and exhaust vents.
5
•The rack for installing the switch has a good cooling system.
•The installation site has a good cooling system.

Space requirement
For adequate ventilation and ease of maintenance, consider the following space requirements:
•Make sure the clearance between the rack and walls or other devices is at least 1 m (3.28 ft), and
the headroom in the equipment room is no less than 3 m (9.84 ft).
•Make sure the rack has enough space (height and depth) to install your switches. For more
information about switch specifications, see "Appendix A Technical specifications."

Confirming installation preparations
Before you install an S7508E-X switch, verify that:
•You have read the chapter "Preparing for installation" carefully and the installation site meets all the
requirements.
•A 19-inch rack is ready for use when you install the switch to a rack. For how to install a rack, see
the rack installation guide.
•The rack is sturdy and securely grounded.
•No debris exists inside or around the rack.
•Choose a correct rack mounting position for the switch. Make sure the heaviest device is placed at
the bottom of the rack.
•The total height of the switches to be installed is no higher than the available installation height of
the rack and enough clearance is reserved for cable routing.
•The switch is ready for installation and has been carried to a place near the rack and convenient for
moving.
Attaching slide rails and cage nuts to the rack
Installing slide rails
If the rack has slide rails, skip this section.
Before you attach slide rails to the rack, verify that:
•The slide rails can support the weight of the switch. For the weights of the S7508E-X switch, see
"Appendix A Chassis views and technical specifications."
H3C recommends that you order the H3C Slide Rail Accessories,500mm-800mm (LSTM2KSGD0).
The accessories can be used in racks where the distance between the front and rear rack posts fits
the H3C slide rails:
•When S7508E-X switch are installed in an enclosed cabinet, the distance between the front rack
posts and the front door must be at least 100 mm (3.94 in) for installing cable management
brackets, and the distance between the front rack posts and the rear door must be at least 660 mm
(25.98 in) for the chassis with cards installed.
•To ensure stability of the rack, install the slide rails to the lowest possible position when installing a
single switch on the rack. To install multiple switches on the rack, mount the heaviest switch at the
bottom of the rack.

2. Mark the position on the rack for installing the slide rail:
a. Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes, as shown in Figure 3.
b. Each rack post requires six screws to attach the slide rail. You only need to mark the uppermost
square hole and lowermost square hole for installation.
c. Mark the square holes at the same height on the other three rack posts.
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
wider than that between two adjacent standard installation holes.
