6.11 Power System
Introduction
The subsections that follow describe the removal and replacement of major assemblies in the Power
System.
If all options are installed, most of the major assemblies in the Power System can be removed and
replaced while the HPM remains in operation because of Power Supply Module redundancy and battery
backup power. Observe all precautions mentioned in this text when replacing the Power System
components.

6.12 CMOS Battery Replacement
NiCad batteries
The three NiCad batteries that are installed in the Standard Power System to provide standby power for
the CMOS memory have a tendency to age over a period of time. Aging occurs even if the batteries have
been regularly recharged throughout their lifetime. For this reason, the NiCad batteries should be
replaced after every two years of operation.
