Installation
Disconnection from Supply Source
The power supply of the E5080A is cut off by disconnecting the
plug of the power cable (on either AC outlet side or E5080A 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 E5080A side.
N O T E
Under normal use, never directly interrupt the power supply to
the power cable receptacle on the rear panel when the power
supply is turned 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 turned ON, or turn OFF the
Line Switch, the shutdown process will not work. This could
damage the software and hardware of the E5080A 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.
