The following methods can be used to turn off the power by linking with the server.
• Via the power synchronized unit
Use the power synchronized unit to turn off the ETERNUS DX.
When turning off the ETERNUS DX, the power shuts off after the write data on the cache memory is written
•
back to the drives. As a result, it may take approximately five minutes (or approximately 10 minutes in a
Unified configuration and 20 minutes in a VLAN/Bonding maximum configuration) or a maximum of 10 mi-
nutes (or approximately 40 minutes in a Unified configuration and 50 minutes in a VLAN/Bonding maxi-
mum configuration) for the power supply to be completely turned off.
Do not turn off the power of the ETERNUS DX and the network devices that connect the ETERNUS DX 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 DX.
When using a power synchronized unit for power control, turn off the power of the ETERNUS DX via the pow-
•
er synchronized unit. When a power synchronized unit is connected, the power of the ETERNUS DX is auto-
matically turned on because the power synchronization function is activated.
If the REMOTE LED on the ETERNUS DX is green, turn off the ETERNUS DX by linking with the server. Pressing
•
the Power switch does not turn off the ETERNUS DX.
To turn off the ETERNUS DX, use the Power switch, a power synchronized unit, ETERNUS Web GUI, or ETER-
•
NUS CLI. If any other method is used to turn off the ETERNUS DX, 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.
