SC827 Chassis Manual
4-2
4-2 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 but-
ton 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.
4-3 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.
Alert: This LED is illuminated when an alert condition occurs. •
A solid red light indicates an overheat condition in the system.
A ashing red light which ashes in one second intervals indicates a fan
failure.
A ashing red light which ashes in four second interfals indicates a power
failure. When notied 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, veri-
fy that the heatsinks are installed properly. This LED will remain ashing or on
