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 this 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. An error message is displayed when you turn on the server.

Be sure to consider the following information when you replace the battery in the server:

•You must replace the battery with a lithium battery of the same type from the same manufacturer.

•To avoid possible danger, be sure to read and understand the following safety statement.

•After you replace the system board battery, you must reset passwords, system date and time, and reconfigure the server.
