Control Panel Buttons
There are three push-buttons located on the front of the chassis. These are (in order
from left to right) A UID button, a reset button and a power on/off button.
UID
Depressing the UID (unit identifi er) button illuminates an LED on both the front and
rear of the chassis for easy system location in large stack confi gurations. The LED
will remain on until the button is pushed a second time. Another UID button on the
rear of the chassis serves the same function.
Reset
The reset button reboots the system.
Power
The main power switch is used to apply or remove power from the power supply
to the server system. Turning off system power with this button removes the main
power but keeps standby power supplied to the system.
