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

• Make sure the router and the floor are correctly grounded.

• Take dust-proof measures for the equipment room.

• Maintain the humidity and temperature at acceptable levels.

• Always wear an ESD wrist strap and ESD cloth when touching a circuit board or transceiver module.

The router does not supply an ESD wrist wrap. Prepare an ESD wrist wrap yourself.

• Place the removed memory module, CF card, or interface module on an antistatic workbench, with

the face upward, or put it into an antistatic bag.

• Touch only the edges, instead of electronic components when you observe or move a removed

memory module, CF card, or interface module.

To attach an ESD wrist strap:

1. Wear the wrist strap on your wrist.

2. Lock the wrist strap tight around your wrist to keep 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 grounding terminal.

5. Make sure the rack is correctly grounded.

EMI

Electromagnetic interference (EMI) might be coupled from the source to the router through the following

coupling mechanisms:

• Capacitive coupling

• Inductive coupling

• Radiative coupling

• Common impedance coupling

• Conductive coupling

To prevent EMI, take the following actions:

• Take measures against interference from the power grid.

• Do not use the router together with the grounding equipment or lightning-prevention equipment of

power equipment, and keep the router far away from them.

• Keep the router far away from high-power radio launchers, radars, and equipment with high

frequency or high current.

• Use electromagnetic shielding when necessary.

Lightning protection

To better protect the router from lightning, do as follows:

• Make sure the grounding cable of the chassis is correctly grounded.

• Make sure the grounding terminal of the AC power receptacle is correctly grounded.

• Install a lightning arrester at the input end of the power supply to enhance the lightning protection

capability of the power supply.
