Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
NOTE: To return to normal operation, apply power to the storage subsystem. The
cache battery will be enabled when the subsystem is powered on.
Restarting the Subsystem
Use the following steps to restart a subsystem:
1. Plug in the subsystem’s power cord, if it is not already plugged in.
2. Turn on the subsystem. The controllers automatically restart and the ECBs
automatically re-enable themselves to provide backup power to the cache
modules.
