Troubleshooting the Server Module Battery
Problem
l System message indicates a problem with the battery
l System Setup program loses system configuration information
l System date and time do not stay current
Each server module contains a battery, which maintains the server module configuration, date, and time information in NVRAM when you turn off the server
module. You may need to replace the battery if an incorrect time or date is displayed during the boot routine.
You can operate the server module without a battery; however, the server module configuration information maintained by the battery in NVRAM is erased
each time you remove power from the server module. Therefore, you must re-enter the system configuration information and reset the options each time the
server module boots until you replace the battery.
Action
1. Re-enter the time and date through the System Setup program. See "Using the System Setup Program" in your User's Guide.
2. Remove the server module for at least one hour. See " Removing a Server Module " in "Installing System Options."
3. Install the server module. See " Installing a Server Module " in "Installing System Options."
