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 serverboard, 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 serverboard node, for those serverboards which
support it. Once the blue light is activated, the unit can be easily located in very
large racks and server banks.
