Removing the BBWC battery pack CAUTION: After the server is powered down, wait 15 seconds and then check the amber LED before unplugging the cable from the cache module. If the amber LED blinks after 15 seconds, do not remove the cable from the cache module. The cache module is backing up data, and data is lost if the cable is detached. CAUTION: Do not detach the cable that connects the battery pack to the cache module. Detaching the cable causes any unsaved data in the cache module to be lost. To remove the component: 1. Power down the server (on page 26). 2. Extend the server from the rack. 3. Remove the access panel (on page 28). 4. If the existing cache is connected to a battery, observe the BBWC Status LED ("Battery pack LEDs" on page 101). o If the LED is flashing every 2 seconds, data is still trapped in the cache. Restore system power, and then repeat the previous steps. o If the LED is not illuminated, disconnect the battery cable from the cache. 5. Disconnect the cable. 6. Remove the battery pack. The SPI board is removed for clarity. To replace the component, reverse the removal procedure. Illustrated parts catalog 64
