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 SR6602-X does not provide any ESD wrist strap. Prepare it yourself.
To prevent electrostatic discharge (ESD), note the following guidelines:
•
Make sure the router and rack are well grounded.
•
An anti-static floor is installed and well grounded.
•
Maintain the humidity and temperature at a proper level in the equipment room. For more
information, see “
Temperature and humidity .”
•
Always wear an ESD wrist strap and ESD cloth when touching a circuit board, interface module,
or transceiver module.
•
Place the removed memory module, CF card, FIP, HIM, or MIM 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, HIM, or MIM.
