The Operator Panel
The Operator Panel is the first level of user interface to SystemGuard.
The Operator Panel has the following features:
Power button It should generally stay pushed in all the time if you want to be able to
power on or off the system remotely.
Reset button It resets SystemGuard to the Init phase and, depending on the key position,
reboots the system to Maintenance or to AIX Multi-User.
LCD display It is made of two rows of sixteen characters. It displays the word Stand-By
in the Stand-By phase, or it displays the usual three-digit boot up codes.
Physical Key It uses the international symbols for Normal, Secure and Service modes.
This key should generally stay in the Normal position because the modes
can be changed electronically when the physical key is in the Normal
position.

Note: In the 7012 G Series the system board contains the NVRAM, the NVRAM battery,
and the TOD. You can drain NVRAM by disconnecting the NVRAM battery.
When NVRAM is drained it results in a reset of the TOD to 1969 which affects
applications. Draining NVRAM also causes a loss of configuration data.
