3-3 Control Panel LEDs
The control panel located on the front of the SC822R-400RC chassis has
five LEDs. These LEDs provide you with critical information related to dif-
ferent parts of the system. This section explains what each LED indicates
when illuminated and any corrective action you may need to take.
!
Power Fail: Indicates a power supply unit has failed and will need to
be replaced. Refer to Chapter 6 for details on replacing power supply
units. This LED should be off when the system is operating normally.
!
Overheat: Indicates an overheat condition in the chassis. This may
be caused by cables obstructing the airflow in the system or the ambient
room temperature being too warm. You should also check to make sure
that the chassis cover is installed and that all fans are present and operat-
ing normally. Verify that the heatsinks are installed properly (see the pro-
cessor installation section in Chapter 5). Finally, check the air seals for
damage. The air seals are located under the blower fans and beneath the
frame cross section that separates the drive bay area from the motherboard
area of the chassis.
