•
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.
