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 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

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 Attach the ESD-preventive wrist strap to the rack with the alligator clips.

Step4 Make sure that the rack is well grounded.
