Chapter 2 Basic Operation
2.1 Powering On and Off
When turning off the ETERNUS DX, the power shuts off after the write data in the cache memory is writ-
•
ten back to the drives. As a result, it may take approximately one to six minutes (approximately two to
six minutes in a Unified 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
•
power synchronized unit. When a power synchronized unit is connected, the power of the ETERNUS DX is
automatically turned on because the power synchronization function is activated.
After power-off, wait for about one minute before turning power on again.
