Preparing for installation

H3C WX3500H access controllers include the following models:

•WX3508H.

•WX3510H.

•WX3520H.

•WX3540H.

Safety recommendations

To avoid any equipment damage or bodily injury, read the following safety recommendations before

installation. Note that the recommendations do not cover every possible hazardous condition.

Safety symbols

When reading this document, note the following symbols:

WARNING means an alert that calls attention to important information that if not understood or

followed can result in personal injury.

CAUTION means an alert that calls attention to important information that if not understood or

followed can result in data loss, data corruption, or damage to hardware or software.

General safety recommendations

•Make sure the installation site is flat, vibration-free, and away from electromagnetic

interferences. Make sure ESD and anti-slip measures are in place.

•Do not place the device on an unstable case or desk. The device might be severely damaged in

case of a fall.

•Keep the chassis and installation tools away from walk areas.

•Keep the chassis clean and dust-free.

•Do not place the device near water or in a damp environment. Prevent water or moisture from

entering the device chassis.

•Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the

device free of obstruction.

•Make sure the operating voltage is in the required range.

•Use a screwdriver to fasten screws.

•After you move the device from a location below 0°C (32°F) to the equipment room, follow these

guidelines to prevent condensation:

{Wait a minimum of 30 minutes before unpacking the device.

{Wait a minimum of 2 hours before powering on the device.

Electrical safety

•Carefully examine your work area for possible hazards, such as moist floors, ungrounded

power extension cables, or missing safety grounds.

•Locate the emergency power-off switch in the room before installation. Shut off the power

immediately if an accident occurs.

•Unplug all the external cables (including power cords) before moving the chassis.

•Do not work alone when you operate the device with the device powered on.

•Always verify that the power has been disconnected when you perform operations that require

the device to be powered off.

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.

CAUTION:

•Before you remove the optical fiber connector from a fiber port, execute the shutdown command

in interface view to shut down the port.

•Insert a dust cap into any open optical fiber connector and a dust plug into any open fiber port o

transceiver module port to protect them from contamination and ESD damage.

Examining the installation site

The device can only be used indoors. To ensure correct operation and a long lifespan for your device,

the installation site must meet the requirements in this section.

Temperature and humidity

Maintain the temperature and humidity in the equipment room at acceptable levels.

•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 captive screws and circuit failure.

•High temperature can accelerate the aging of insulation materials and significantly lower the

reliability and lifespan of the switch.

To ensure correct operation of the device, the equipment room must meet the temperature and

humidity requirements listed in Table 1.

Table 1 Temperature/humidity requirements in the equipment room

Temperature Humidity

0°C to 45°C (32°F to 113°F) 5% RH to 95% RH, noncondensing

Cleanliness

Dust buildup on the chassis can 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. To ensure correct operation, the

equipment room must meet the dust concentration requirements listed in Table 2.

Table 2 Dust concentration limit in the equipment room

Substance Concentration limit (particles/m3)

Dust particles

≤3 x 104

(No visible dust on desk in three days)

NOTE:

Dust particle diameter ≥5 µm

To eliminate corrosion and premature aging of components, the equipment room must also meet

limits on salts, acids, and sulfides, as shown in Table 3.

Table 3 Harmful gas limits in an equipment room

Gas Max. (mg/m3)

SO20.2

H2S 0.006

NH30.05

Cl20.01

NO20.04

Cooling

The device uses left-to-right airflow. For adequate heat dissipation, make sure the following

requirements are met:

•A minimum clearance of 100 mm (3.94 in) is reserved around the air vents.

•The rack has a good ventilation system.

Figure 1 Airflow through the chassis (WX3508H)

ESD prevention

To prevent electrostatic discharge (ESD), follow these guidelines:

•Ground the device and rack or workbench reliably.

•Take dust-proof measures for the equipment room. For more information, see "Cleanliness."
