3-3
plies are hot-plug units, you do not need to remove power from the system
when replacing. (The third power supply unit is a backup that activates
automatically to keep power supplied to the system.)
z
Fan Fail: Indicates a system fan failure. This may be one or more of
the four hot-swap intake fans or the one exhaust fan. A fan failure is
accompanied by an audible alarm, which you can disable with the alarm
switch on the control panel. When a fan stops working, all the other sys-
tem fans will increase their RPM to compensate until the failed unit is re-
placed. (See Section 6-2 for more details.) Refer to Section 6-3 for in-
structions on replacing system fans. It is unnecessary to power down the
system as these are hot-swap fans. Note: You must use the exact same
brand and rating of fan for replacement. These can be obtained directly
from Supermicro.
z
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.
z
SCA Channel: Indicates an overheat condition in the area of the SCA
SCSI drives and backplane. 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.
