Turning the 
Power Off
Procedures for turning off the ATM Switch's power are shown below.
1.
Turn off the power switch on the back of the equipment. If the power unit is 
redundant, turn off both power switches.
2.
Confirm that the POWER LED and the READY LED in the lower right area 
of the front of the ATM Switch are off.
All communications will be severed when the power is turned off. All 
unsaved setting data will also be lost. In principle, do not allow anyone 
other than the system manager and service personnel to touch the power 
switch.
To replace one of the power units during operation, only turn off the power of the
power unit you wish to replace.
