Replacing System Components
Powering Down the High-performance NAS Platform for Shipment or
Storage
This procedure should be followed whenever a High-performance NAS Platform is to be
powered down and it will be left off for more than a day. If, however, the system is being
restarted/power-cycled, this procedure is not necessary.
1. From the server console, run the CLI command
shutdown –-ship
.
2. Wait for the console to output the message
Information: Server has shut
down
.
3. Power down the High-performance NAS Platform by switching off both PSU
modules.
4. Wait 10-15 seconds, then check that the NVRAM status LED on the FSB module is
off.
• If the NVRAM status LED is off, the batteries in the PSU will no longer
power the NVRAM, and the PSUs are shut down correctly for storage and/
or shipment.
• If the NVRAM status LED is on (either green or amber), then remove both
PSU modules simultaneously, wait for at least 10 seconds, and replace the
PSUs in the chassis.
• If the High-performance NAS Platform fails to shut down properly or to
verify that the NVRAM has not entered the battery powered back up state
when the PSUs are switched off, remove both PSU modules.
5. Optionally, you can remove the PSUs from the High-performance NAS Platform to
fully disengage them from the system.
Note:
Complete battery discharge can also happen if the High-performance NAS
Platform is shut down correctly but left in an unpowered state for more than 20
days, with the PSU modules plugged in. If the High-performance NAS Platform is to
be left powered off for any significant period of time, remove the PSU modules from
the chassis.
For long term storage of PSU spares, contact a support representative at Hitachi Data
Systems.
When the system is shutdown under normal circumstances, depending on the battery
charge level, the battery can last from 1 to 6 months. Contact a BlueArc representative
for special instructions if servers or PSUs will be in storage for more than 1 month.
Special provisions will be required for field or factory recharging and retesting of PSUs.
