1 Preparing for installation

The figures in this document are for illustration only.

Safety recommendations

To avoid possible bodily injury and equipment damage, read all safety recommendations carefully before installation. Note that 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 power module, or the air vents of the 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 S10500X switch, follow these guidelines:

·     Remove all external cables, including the power cords, before moving the chassis.

·     Moving the chassis requires a minimum of two people, and you can use a mechanical lift as needed.

·     Lift and put down the chassis slowly and never move suddenly.

·     Hold the handles on 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 "Grounding 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 "Attaching an ESD wrist strap."

·     Hold a PCB by its edges. Do not touch any electronic components or printed circuit.

·     Put cards away in ESD bags for future use.

Laser safety

	WARNING! 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 S10500X switches are Class 1 laser products.

Examining the installation site

The H3C S10500X switches must 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

Make sure the floor can support the total weight of the rack, chassis, cards, power modules, and all other components. Additionally, the floor loading plan must also consider system expansion, such as adding more cards. For more information, see H3C S10500X Switch Series Hardware Information and 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.

 

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

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 cause problems including loose mounting screws and circuit failure.

Table 1-2 Humidity requirements

Humidity	Range
Operating humidity	5% RH to 95% RH, noncondensing
Storage humidity	5% RH to 95% RH, 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 1-3 Dust concentration limits in the equipment room

Substance	Particle diameter	Concentration limit
Dust particles	≥ 0.5 µm	≤ 3.5 × 106 particles/m3
Dust particles	≥ 5 µm	≤ 3 × 104 particles/m3
Dust (suspension)	≤ 75 µm	≤ 0.2 mg/m3
Dust (sedimentation)	75 µm to 150 µm	≤ 1.5 mg/(m2h)

 

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 1-4.

Table 1-4 Corrosive gas concentration limits in the equipment room

Gas	Average concentration (mg/m3)	Maximum concentration (mg/m3)
SO2	0.3	1.0
H2S	0.1	0.5
Cl2	0.1	0.3
HCI	0.1	0.5
HF	0.01	0.03
NH3	1.0	3.0
O3	0.05	0.1
NOX	0.5	1.0

 

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.

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. For more information about grounding the switch, see "Grounding the switch."

Make sure the resistance between the chassis and the ground is less than 1 ohm.

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 H3C S10500X Switch Series Hardware Information and Specifications.

2.     Select power modules and 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 H3C S10500X Switch Series Hardware Information and Specifications.

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.

Cooling

Plan the installation site for adequate ventilation.

·     Leave a minimum clearance of 10 cm (3.94 in) around 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 for the chassis meets the airflow design of the installation site.

The direction of the airflow is similar for the S10506X and S10510X chassis. Figure 1-1 uses the S10506X as an example. Figure 1-2, Figure 1-3, and Figure 1-4 show the direction of the airflow through the S10508X, S10508X-V, and S10516X chassis, respectively.

Space

For easy installation and maintenance, follow these space requirements:

·     Reserve a minimum clearance of 1 m (3.28 ft) between the rack and walls or other devices.

·     For heat dissipation, make sure the headroom in the equipment room is no less than 3 m (9.84 ft).

·     Make sure the rack has enough space to accommodate the switch. See Table 1-5 for rack requirements. For more information about chassis dimensions, see H3C S10500X Switch Series Hardware Information and Specifications.
