When the server is on, review the POST message before plugging or unplugging the
cable from the battery module.

Memory

The Smart Array 5i Plus Controller and BBWCE have 64-MB total memory for code,
transfer buffers, and read/write cache.

Controller Interface

The Smart Array 5i Plus Controller and BBWCE support Wide Ultra3 and Wide
Ultra2 SCSI devices that use low voltage differential signaling (LVDS) on the SCSI
bus.
The Smart Array 5i Plus Controller and BBWCE do not support Wide SCSI-3
devices that use the single-ended (SE) signaling protocol.

Drive Array Technology

Drive array technology distributes data across a series of hard drives to unite physical
drives into one or more logical drives. This technology enables concurrent access to
data on multiple drives in the array and yields faster input/output rates than those
using non-arrayed drives. You may set each logical drive in the array to a different
fault-tolerant configuration. The Smart Array 5i Plus Controller and BBWCE manage
the drive array independent of the host processor.

If the amber LED blinks after 15 seconds, do not remove the cable from the
battery module. This module is backing up data and data will be lost if the cable
is detached.
If neither LED blinks after 15 seconds, it is safe to remove the cable from the
battery module.
