When the ETERNUS AF is turned off, the power shuts off after the write data in the cache memory is written
back to the drives. As a result, it may take approximately eight minutes or up to 10 minutes maximum for
the power supply to be completely turned off.
•
Do not turn off the power of the
ETERNUS AF and the network devices that connect the ETERNUS AF to a
server while the server is operating. This may result in the loss of data or prevent data from being saved in
the ETERNUS AF.
•
When using a power synchronized unit for power control, turn off the power of the ETERNUS AF via the pow-
er synchronized unit. When a power synchronized unit is connected, the power of the ETERNUS AF is auto-
matically turned on because the power synchronization function is activated.
•
To turn off the ETERNUS AF250 S2, use the Power switch, a power synchronized unit, ETERNUS Web GUI, or
ETERNUS CLI. If any other method is used to turn off the ETERNUS AF, the replacement cycle for the battery
is shortened significantly because the battery continues to charge and discharge.
•
After power-off, wait for about one minute before turning power on again.
