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.
