• 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.
• If the REMOTE LED on the ETERNUS DX500 S5/DX600 S5 is green, turn off the ETERNUS DX500 S5/DX600
S5 by linking with the server. Pressing the Power switch does not turn off the ETERNUS DX500 S5/DX600
S5.
• To turn off the ETERNUS DX, 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 DX, the replacement cycle for the
battery is shortened significantly because the battery continues to charge and discharge.
