3-3 Control Panel LEDs
In addition to the LEDs built into the power and UID buttons, each of the four control
panels located on the front of the SC827T-1200B chassis has two LEDs that provide
you with critical information related their own node. This section explains what each
LED indicates when illuminated and any corrective action you may need to take.
Overheat/Fan Fail
When this LED is solid on it indicates an overheat condition. When it fl ashes
quickly (~ once every second), it indicates a fan failure. When it fl ashes slowly (~
once every four seconds) it indicates a power supply failure. An overheat condi-
tion 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 cover is properly installed. Finally, verify that the heatsinks are
installed properly (see Chapter 5). This LED will remain fl ashing or on as long as
the indicated condition exists.
