Overview
There are several LEDs on the front panel and two on the Serial ATA drive carrier to
keep you constantly informed of the overall status of the system as well as the activity
and health of specific components. There are also buttons on the chassis control panel.
This chapter explains the meanings of all LED indicators and the appropriate response
you may need to take.

Indicates power is being supplied to the
system's power supply units. This LED should
normally be illuminated when the system is
operating.
Indicates network activity when flashing.
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
operating normally. Finally, check the air seals
for damage. The air seals are located under the
blower fan and beneath the frame cross section
that separates the drive bay area from the
motherboard area of the chassis.
