Replacing the system board battery
Attention: Do not open your server or attempt any repair before reading and understanding the “Safety information”
on page iii and “Guidelines” on page 85.
This topic provides instructions on how to replace the system board battery.
Your server has a special type of memory that maintains the date, time, and configuration information for
built-in features. The system board battery keeps the information active when you turn off the server. The
system board battery normally requires no charging or maintenance throughout its life; however, no battery
lasts forever. If the system board battery fails, the date, time, and configuration information, including
passwords, are lost and an error message is displayed when you turn on the server.
