Battery-backed write cache option

Along with the cache module, the battery pack provides transportable data
protection, increases overall controller performance, and maintains any cached
data for up to 72 hours. The NiMH batteries in the battery pack are continuously
recharged through a trickle-charging process whenever the system power is on.
For information on BBWC LEDs, refer to "Battery-backed write cache LEDs (on
page 32)" and "Battery-backed write cache LED statuses (on page 32)."
WARNING: The potential for personal injury exists if a hot
surface is contacted. Use caution while performing hot-plug
procedures.
NOTE: This feature applies only to SCSI models.
