Powering down the server for maintenance
This procedure should be followed whenever a server is to be powered down
and will be left off for less than a day. If, however, the system is being
rebooted, this procedure is not necessary.
Procedure
1. Shut down the server(s) as described in Rebooting or shutting down a
server on page 81 .
2. If your system is configured with an external System Management Unit
(SMU), depress the red button located on the right of the unit to turn it
off (an internal SMU is turned off when the server shuts down).
3. Power off the storage subsystems, beginning with the enclosures that
house the RAID controllers.
4. Power off the expansion enclosures for the storage subsystems.
Powering down the server for shipment or storage
Follow this procedure whenever a server is to be powered down and will be
left off for more than a day. If the system is being restarted or power-cycled,
this procedure is not required.
When the system is properly shut down, depending on the battery charge
level, the battery may last up to one year without being charged or
conditioned . See
NVRAM backup battery pack on page 42 for details.
Contact your representative for special instructions if servers or NVRAM
battery backup packs will be in storage for more than one year. Special
provisions are required for field or factory recharging and retesting of NVRAM
battery backup packs.
Procedure
1. From the NAS operating system (Bali) console, issue the command:
shutdown –-ship --powerdown
2. Wait until the console displays the message
Information: Server has
shut down
and the rear panel LEDs turn off.
Note: The PSUs continue to run, and the PSU LEDs stay on.
3. Power down the server by removing the power cables from the PSU
modules.
4. Wait 10-15 seconds, then check that the NVRAM Status LED on the rear
panel of the server is off.
