Esd Prevention; Emi; Lightning Protection; Installation Accessories - H3C WX2510H Installation Manual

ESD prevention

To prevent electrostatic discharge (ESD), follow these guidelines:
•
Ground the device reliably.
•
Take dust-proof measures for the equipment room.
•
Maintain the humidity and temperature at acceptable levels.
•
Always wear an ESD clothing and ESD gloves when you are operating the device. To avoid
electric shocks, do not wear conductive objects such as jewelry and watch.

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, 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 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.

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 supply to enhance the lightning
protection capability of the power supply.
