Preparing for installation
H3C S12500-X Switch Series includes the following models:
•S12510-X AC.
•S12510-X DC.
•S12516-X AC.
•S12516-X DC.
Safety recommendations
To avoid possible bodily injury and equipment damage, read Compliance and Safety Manual provided
with the switch and all safety recommendations in this chapter carefully before installation. 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 anti-slip measures are in place.
•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 electricity hazards, such as ungrounded power extension cables,
missing safety grounds, and wet floors.
•Locate the emergency power-off switch in the room before installation so you can quickly shut power
off when an electrical accident occurs.
•Remove all external cables, including power cords, before moving the chassis.
•Do not work alone when the switch has power.
•Always verify that power has been disconnected from a circuit.
Handling safety
CAUTION:
Do not hold the handle of a fan tray or a power distribution box, or the air vents of chassis to move the
switch. Any attempt to move the switch with these parts might cause equipment damage and even
bodily injury.
When you move an H3C S12500-X switch, follow these guidelines:

2
•Remove power modules, cards, and all external cables, including the power cords, before moving
the chassis.
•Cooperate with a minimum of four people to move the chassis, and use a mechanical lift as
needed.
•Lift and put down the chassis slowly and never move suddenly.
•Hold the handles on both sides of the chassis.
ESD prevention
To prevent the electric component from being damaged by electrostatic discharge (ESD), follow these
guidelines:
•Ground the switch reliably. 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 FRUs. 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 away in antistatic bags for future use.
Laser safety
W
ARNING!
Do not stare into any fiber port or view directly with non-attenuating optical instruments when the switch
has power. The laser light emitted from the fiber port might hurt your eyes.
The H3C S12500-X switches are Class 1 laser products.
Examining the installation site
The H3C S12500-X switches must be used indoors. To ensure correct operation and long lifespan of your
switch, the installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, cards, power modules, and all other
components. To mount the switch in a rack, make sure the slide rails can support the total weight of the
switch and its accessories (cards, power modules, and transceiver modules).
Additionally, the floor and slide rail loading plan must also consider system expansion, such as adding
more cards. For more information, see "Appendix A Chassis views and technical specifications."
Temperature
CAUTION:
If condensation appears on the chassis when you move it to a high-temperature environment, dry the
chassis before powering it on to avoid short circuits.

3
To ensure the normal operation of the switch, make sure the room temperature meets the requirements
in Table 1.

e
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 2.
•Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
•Lasting low relative humidity can cause washer contraction and ESD and cause problems including
loose mounting screws and circuit failure.

e
Operating humidity 5% to 95%, noncondensing

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 3 Dust concentration limit in the equipment room
Substance Concentration limit (

articles/m3)
Dust particles ≤3 x 104
(No visible dust on desk in three days)
NOTE:
Dust particle diameter ≥5 μm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 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.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
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 grounding the switch, see "Installing the switch."
Power
Perform the following tasks to meet the power requirements:
1. Calculate the system power consumption.
The system power consumption varies by card type and density. For more information about
system power consumption calculation, see "Appendix A Chassis views and technical
specifications."
2. Identify the number of power modules.
The total maximum output power of all power modules must be higher than the system power
consumption. For more information about available power modules, see "Appendix B FRUs and
compatibility matrixes."
3. Verify that the power system at the installation site meets the requirements of the power modules,
including the input method and rated input voltage. For more information about power module
specifications, see "Appendix B FRUs and compatibility matrixes."

5
Cooling
Plan the installation site for adequate ventilation:
•Leave a minimum of 30 cm (11.81 in) of clearance at the inlet and outlet air vents.
•The rack for the switch has a good cooling system.
•The installation site has a good cooling system.
•Verify that the airflow design of the chassis meets the airflow design of the installation site.

Space
For easy installation and maintenance, follow these space requirements:
•Reserve a minimum of 1.2 m (3.94 ft) of clearance between the rack and walls or other devices.
•Make sure the rack has enough space to accommodate the switch. See Table 5 for rack
requirements. For more information about chassis dimensions, see "Appendix A Chassis views and
technical specifications."

One power cord bracket is delivered with each S12510-X AC switch. Two power cord brackets are
delivered with each S12516-X AC switch.
The procedures for installing a power cord bracket to an S12510-X AC switch or an S12516-X AC switch
are the same. This section describes how to install the power cord bracket to an S12510-X AC switch.
To install the power cord bracket:
1. Unpack the power cord bracket.
2. Place the power cord bracket to the chassis.
3. Align the installation holes on the bracket with those on the chassis.
4. Fasten the screws to secure the power cord bracket.

Attaching the plastic panel
The plastic panel covers air inlet vents and power module slots at the lower part of the front panel. As a
best practice, install and power on power modules and make sure the power modules are operating
correctly before installing the plastic panel.
To install the plastic panel:
1. Unpack the plastic panel, clips, and screws.
2. Secure the clips to both sides of the air inlet vents by using the screws supplied with the plastic
panel, as shown in Figure 5.
Skip this step if the clips have been installed to the switch.
3. Attach the plastic panel to the chassis with the positioning pins that align with holes in the chassis.
4. Push in the plastic panel until it clicks into place, as shown in Figure 7.
