Control Panel Button
Power: The main power button on each of the four control panels is used to apply
or remove power from the power supply to each of the four systems in the chassis.
Turning power to the system off with this button removes the main power, but keeps
standby power supplied to the system. Therefore, you must unplug the AC power
cord from any external power source before servicing. The power button has a
built-in LED which will turn green when the power is on.
UID: When used with a UID compatible motherboard, the UID button 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 motherboard 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.
