Replacing The Rtc Battery - GE PACSystems RXi Box IPC User Manual

Replacing the RTC Battery

The real-time clock is backed up by a lithium coin cell battery, IC690ACC001. The RTC battery has
an estimated life of 5 years and must be replaced every 5 years on a regular maintenance
schedule. There are no diagnostics or indicators to monitor RTC battery status.
If the RTC battery fails, the CPU date and time is reset to 12:00 AM, 01-01-2008 at startup. The
CPU operates with a failed or missing RTC battery; however the initial CPU TOD clock information
will be incorrect.
You will need the following:
GFK-2785C
To avoid damage from electrostatic discharge, adhere to the following
precautions when opening the IPC enclosure:

Wear a properly functioning antistatic strap and be sure that you are fully
grounded. Never touch any components inside the IPC unless you are
wearing an antistatic strap.

The IPC should be placed on a static-safe surface, facilitated by
antistatic mats.

Extra caution should be taken in cold, dry weather, when static charges
can easily build up.
