K2 Level 2 RAID Storage power-down
Before turning on the AC power, check for loose disk drives by pushing each disk
drive.
2. Turn on power switches on both power supplies.
When turning on the power switches, confirm that the POWER GOOD LEDs
(green) on all the power supplies and POWER LEDs (green) on the front panel of
the RAID chassis and Expansion chassis go on. The power supply starts, and the
POWER LED (green) is on while the power switches are on.
The RAID chassis performs the self-test and initialization immediately after the
power is turned on. When the self-test and initialization terminate and the RAID
chassis becomes ready, the READY LED of the controller stops flashing and enters
the on state.
3. Confirm that the READY LED is on, and then turn on the host system.
The chassis takes four minutes (at maximum) to start.
Refer to sections in
Chapter 3, “Servicing the K2 Level 2 RAID”
for information
on interpreting status LED behavior.
NOTE: Refer to the K2 Storage System Instruction Manual for complete system
power-up procedures.
K2 Level 2 RAID Storage power-down
NOTE: If your K2 Level 2 RAID Storage system is part of a shared storage system,
refer to the K2 Storage System Instruction Manual for instructions on shutting down
the shared storage before powering down a K2 Level 2 RAID Storage.
To power-down the K2 Level 2 RAID Storage correctly:
1. Stop all read/write activity to the K2 Level 2 RAID Storage storage system.
2. On the RAID controller chassis, turn off power switches on both power supplies.
3. On the Expansion chassis, turn off both power switches on both power supplies.
Alternatively, turn off all power switches of the RAID controller chassis and the
Expansion chassis at the same time.
CAUTION: You must always power down the K2 Level 2 RAID
controller chassis prior to, or at the same time as the K2 Level 2
Expansion Chassis.
“K2 Level 2 RAID Storage power-up and initialization” on
Battery Backup
Every K2 Level 2 RAID chassis power supply 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 power supply module.
