Warning:
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.
Warning:
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.
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.
points on page 76 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.
• Keep cards installed in the system as much as possible to avoid dirty contacts and
unnecessary wear.
• Store cards in a cool, dry, dust-free area.
