Description
1
Power Button
The main power button on each of the eight control panels is used to apply or remove
power from the power supply to each of the eight systems in the chassis. Turning off
system power with this button removes the main power, but keeps standby power
supplied to the system. Therefore, you must unplug system before servicing. The power
button has a built-in LED which will turn green when the power is on.

UID LED
When used with a UID compatible serverboard, the UID indicator is used to turn on or
off the blue light function of the LED. This is built into the front side of the UID button
and at the rear end of each serverboard node, for those motherboards which support it.
Once the blue light is activated, the unit can be easily located in very large racks and
server banks.
1.5 Server Chassis Features
