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.

2
•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
r
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.

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."

4
•Maintain the humidity and temperature at acceptable levels. For more information, see
"Temperature and humidity."
•Before working with the device, wear an ESD wrist strap or gloves and ESD garment, and
remove conductive objects such as jewelry or watch. Make sure the wrist strap makes good
skin contact and is reliably grounded.
•Always remember to wear an ESD wrist strap when working with a transceiver module.
No ESD wrist strap is provided with the device. Prepare one yourself.
To attach an ESD wrist strap:
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to maintain good contact with the skin.
3. Secure the wrist strap lock and the alligator clip lock together.
4. Attach the alligator clip to the rack.
5. Make sure the rack is reliably grounded.

(3) Alligator clip
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the device and application
system, adversely affect the device 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.

5
•Keep the device 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. If you must route interface cables outdoors, install
network port lightning protectors.
Lightning protection
To better protect the device from lightning, follow these guidelines:
•Make sure the grounding cable of the chassis is reliably grounded.
•Make sure the grounding terminal of the AC power receptacle is reliably grounded.
•Install a lightning protector at the input end of the power module to enhance the lightning
protection capability of the power supply.
Installation accessories
The installation accessories vary by device model. Table 4 describes the installation accessories
available for the access controllers.
