LEDs
The control panel located on the front of the SC748TQ-R1000/SC748S-R1000
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.
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.
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 obstructing 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.
NIC2:
Indicates network activity on GLAN2 when fl ashing .
NIC1:
Indicates network activity on GLAN1 when fl ashing.
