Control Panel LEDs
The control panel located on the front of the chassis has several LEDs. These LEDs provide you
with critical information 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.
Power Fail
The power fail LED indicates a power supply module has failed as shown in Figure 3-4 . The
(optionally available) second power supply module will take the load and keep the system running
but the failed module will need to be replaced. Refer to Chapter 6 for details on replacing the
power supply. This LED should be off when the system is operating normally.

Power Fail LED
Overheat/Fan Fail
When the red overheat/fan LED flashes (shown in Figure 3-5 ), it indicates a fan failure. When on
continuously it indicates an overheat condition, which may be caused by cables obstructing the
airflow in the system or the ambient room temperature being too warm.
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 are installed. This LED will remain flashing
or on as long as the indicated condition exists.
