3-2 Control Panel Buttons
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 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 poer 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.
3-3 Control Panel LEDS
The four control panels are located on the front handle of the SC827 chassis. Each
control panel has two additional LEDs. These LEDs provide you with critical informa-
tion related to different parts of the system. This section explains what each LED
indicates when illuminated and any corrective action you may need to take.

A solid red light indicates an overheat condition in the system.
A fl ashing red light which fl ashes in one second intervals indicates a fan failure.
A fl ashing red light which fl ashes in four second interfals indicates a power
failure. When notifi ed of an alert, check the routing of the cables and make sure
all fans are present and operating normally. You should also check to make
sure that the chassis covers and air shrouds are installed. Finally, verify that the
heatsinks are installed properly. This LED will remain fl ashing or on as long as
the temperature is too high or a fan does not function properly.
