Upgrade and maintenance information
Risk of equipment damage
!
Module covers are not hinged; when removing, do not let
go of the covers. Lift covers away from the module and
set them out of your work area.
WARNING
Risk of personal injury
Circuit cards can contain a lithium battery. There is a
danger of explosion if the battery is replaced incorrectly.
!
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 personal injury and equipment damage when handling circuit cards,
follow the guidelines listed below:
•
Wear a properly connected antistatic wrist strap when you work with
switching equipment. If a wrist strap is not available, regularly touch one
of the bare metal strips in a module to discharge static. Figure 11 on
page 82 shows the recommended connection points for the wrist strap
and the bare metal strips that you should touch.
•
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.
