PFR600/E power-down
IMPORTANT: If your PFR600/E system is part of an Open SAN, refer to the Open
SAN Instruction Manual for instructions on shutting down the Open SAN before
powering down a PFR600/E.
To power-down the PFR600/E correctly:
1. Stop all read/write activity to the PFR600/E storage system.
2. Power-down the RAID storage system by powering-down the PFR600 Controller
chassis prior to, or at the same time as with the PFR600E Expansion chassis.
>>> CAUTION: You must always power down the PFR600 RAID Controller chassis
prior to, or at the same time as the PFR600E Expansion Chassis.
To turn on power, refer to “PFR600/E power-up and initialization” on page 36 .
Battery Backup recharge
Every PFR600/E RAID controller includes a backup battery so that if electrical power
is lost, data stored in cache memory will be saved.
Data store cache is not used in Profile storage systems, so the Battery Backup module is
not used, even though it ships as part of the LBB module.
