SC827 Chassis Manual

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 flashing red light which flashes in one second intervals indicates a fan failure.

A flashing red light which flashes in four second interfals indicates a power failure. When notified 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 flashing or on
