 Circuit card installation

To avoid personal injury and equipment damage, review the following 
guidelines before handling system equipment.

To avoid damage to circuit cards from static discharge, wear a properly 
connected antistatic wrist strap when you work on system equipment. If a 
wrist strap is not available, regularly touch one of the bare metal strips in a 
module to discharge static. Figure 15 on 

 shows the recommended 

connection points for the wrist strap and the bare metal strips you should 
touch.

Handle circuit cards as follows:

•

Unpack or handle cards away from electric motors, transformers, or 
similar machinery.

•

Handle cards by the edges only. Do not touch the contacts or 
components.

•

Set cards on a protective antistatic bag. If an antistatic bag is not 
available, hand-hold the card, or set it in a card cage unseated from the 
connectors.

•

Store cards in protective packing. Do not stack cards on top of each other 
unless they are packaged.

Module covers are not hinged; do not let go of the covers. 
Lift covers away from the module and set them out of your 
work area.

Circuit cards may contain a lithium battery. There is a 
danger of explosion if the battery is incorrectly replaced. 
Do not replace components on any circuit card; you must 
replace the entire card.

Dispose of circuit cards according to the manufacturer’s 
instructions.
