3-3 Control Panel LEDs
The control panel located on the front of the SC748TQ-R1200 chassis has fi ve
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.
Overheat/Fan Fail
When this LED fl ashes it indicates a fan failure. When on continuously (on and not
fl ashing) it indicates an overheat condition, which may be caused by cables ob-
structing the airfl ow 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.
Finally, verify that the heatsinks are installed properly (see Chapter 5). This LED
will remain fl ashing or on as long as the overheat condition exists.
Power Fail
Indicates a power supply module has failed. This should be accompanied by an
audible alarm. A backup 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 failed power supply modules. This LED should be off when
the system is operating normally.
