ESD prevention
CAUTION:
•
Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range
of 1 to 10 megohm (Mohm) between human body and the ground.
•
The L1000-A does not provide any ESD wrist strap. Prepare it yourself.
To prevent electrostatic discharge (ESD), follow these guidelines:
•
Make sure the L1000-A and rack are correctly grounded.
•
An anti-static floor is installed and correctly grounded.
•
Maintain the humidity and temperature at a compliant range in the equipment room. For more
information, see "
•
Always wear an ESD wrist strap and ESD cloth when touching a circuit board, interface module, or
transceiver module.
•
Place the removed power modules and interface modules 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.
Make sure the rack is correctly grounded before you wear an ESD wrist strap.
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.
Attach the alligator clip to the chassis.
4.
Make sure the wrist strap is correctly grounded.
