ESD prevention

CAUTION:
Make sure the resistance reading between human body and the ground is in the range of 1 to 10
megohms (Mohms).
To prevent electrostatic discharge (ESD), note the following guidelines:
•
Make sure the router and the floor are reliably grounded.
•
Take dust-proof measures for the equipment room.
•
Maintain the humidity and temperature in the acceptable range.
•
Always wear an ESD wrist strap when touching a circuit board or transceiver module.
•
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 observing or moving a removed
memory module, CF card, or interface module.
To attach the 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. Insert the ESD wrist strap into the specially designed hole on the router chassis or attach it to
the grounding screw of the chassis with the alligator clips.
4. Make sure the rack is reliably grounded.
