Battery Module
In Oracle Engineered Systems, storage drive 7 might be populated with a remote battery module for the host bus adapter (HBA) card.
 | Caution - The battery module is not a customer-replaceable unit (CRU) and should not be removed or replaced by customers. The battery module should be removed or replaced only by Oracle Service personnel. |
The battery module is hot-pluggable and provides the backup power subsystem for the Sun Storage 6 Gb SAS PCIe RAID internal host bus adapter (HBA): SG-SAS6-R-INT-Z. It enables Oracle Service personnel to replace the battery at the end of its service life without requiring the server to be powered off.
