152 Upgrading Boardset Components
Replacing the Backup Battery
The lithium battery on the I/O carrier powers the real-time clock (RTC) for three to four years in
the absence of power. When the battery weakens, it loses voltage and the system settings stored in
CMOS RAM in the RTC (e.g., the date and time) can be wrong. Contact your customer service
representative or dealer for a list of approved devices.
WARNING
If the system has been running, any installed processor and heat sink on
the processor board(s) will be hot. To avoid the possibility of a burn, be
careful when removing or installing components that are located near
processors.
The following warning and translations are required by specific certifying agencies to be printed
immediately adjacent to the procedure for removing the RTC.
WARNING
Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type recommended by the equipment
manufacturer. Discard used batteries according to manufacturer’s
instructions.
