Installation
Starting the E5072A
Step 2. Next, if necessary, turn off power supply to the power cable receptacle (Line
Switch) on the rear panel.
Under normal use, never directly interrupt the power supply to the power
cable receptacle on the rear panel when the power supply is on. Always
keep the Line Switch ON and never turn it.
If you directly interrupt the power supply to the power cable receptacle
when the power supply is on, or turn off the Line Switch, the shutdown
process will not work. This could damage the software and hardware of
the E5072A and lead to device failure.
Turning on the power supply after a faulty shutdown may cause the
system to start up in a condition called "safe mode." If this occurs, first
shut down the system to set it to the standby state and then turn on the
power supply again to start up the system in normal mode.

Disconnection from Supply Source
The power supply of the E5072A is cut off by disconnecting the plug of the
power cable (on either AC outlet side or E5072A side). When it is necessary to
disconnect the power supply in order to avoid shock hazards, etc., pull out the
power cable plug from either the AC outlet side or the E5072A side.
