Service considerations for the cache battery pack

To prevent data loss, follow proper procedures before replacing the cache battery pack on the 175 MB cache RAID – dual IOA enablement card.

Attention: To maintain system availability and to prevent possible data loss, it is important to understand that these features have implications on the SAS configuration and data accessibility of the system.

The 175 MB cache Raid – dual IOA enablement card (FC 5662) contains two rechargeable battery packs and battery charger circuitry. Each battery pack provides power for the write cache of an embedded SAS storage adapter. When you replace a failing cache battery pack, be sure to replace the correct battery pack.

Attention: To prevent data loss, follow proper procedures before proceeding with battery replacement. If either of the cache battery LEDs are flashing, do not replace the cache battery pack or you might lose data.
