Powering off the storage system
Procedure
1. Press the main switch for three seconds until the
POWER
LED blinks.
2. Verify that the
POWER
LED on the front of the storage system changes
from green to amber.
It can take from 25 minutes to 4 hours for the
POWER
LED to turn amber,
depending on the configuration of the system (check after 33 minutes).
3. To stop the power supply from supplying power, remove the power cables
from the power supply units on the controller chassis and drive box.
If the storage system is connected to a PDU, you can stop the power
supply by turning off the PDU breaker.
Note: If the storage system does not receive power for more than
six months, the battery can become discharged and possibly
damaged. To avoid this situation, charge the battery for more than
three hours at least once every six months.
