HP SureStore E Disk Array 12H Controller
This document explains how to install batteries, download firmware into a disk array controller, and how to
replace an array controller.
About Battery Packs
If your disk array goes without power, the controller batteries are capable of retaining data in NVRAM for a
minimum of one week. Always perform a successful Shutdown before replacing the batteries. For further
protection, battery packs should be replaced one at a time, so that there is always at least one battery
providing power for memory backup. If the disk array power is to be turned off for an extended period of
time (more than five days), then the NVRAM memory maps should be saved to disk (by successful
Shutdown) and both battery packs should be disconnected to prevent damage to the battery packs and the
controller.
