ESD prevention
To prevent electrostatic discharge (ESD), note the following guidelines:
•
Make sure that the firewall and the floor are well grounded.
• Take dust-proof measures for the equipment room.
• Maintain the humidity and temperature at a proper level.
•
Always wear an ESD-preventive wrist strap when touching a circuit board or transceiver module.
•
Place the removed 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 CF
card or interface module.
To use the ESD-preventive wrist strap, perform the following steps:
Step1
Wear the wrist strap on your wrist.
Step2
Lock the wrist strap tight around your wrist to keep good contact with the skin.
Step3

Step4
Make sure that the rack is well grounded.
