Troubleshooting Checking the Battery Service Date Note Under normal circumstances, replace the BBU every two years. Operating the disk array in a environment with elevated temperature (above 35º C or 95º F), lowers the life expectancy of the BBU. Under these conditions you may need to replace the battery every six months. To check the service date on the BBU: 1. Remove the front cover from the controller enclosure. 2. Locate the Battery Support Information label on the front of the BBU. See Figure 85. The label has three dates: - Date of Manufacture - the date the BBU was built at the factory - Date of Installation - the date the BBU was installed into the controller module - Replacement Date - the date the BBU should be replaced 3. Check the replacement date. If it is time to replace the battery, see "Battery Backup Unit (BBU) Removal/Replacement" on page 325. Otherwise, proceed to Step 4. 4. Reinstall the front cover on the controller enclosure. Controller Enclosure Troubleshooting 265
