Troubleshooting
The key to problem solving in this system is to try to isolate the problem to a specific
subsystem. By comparing what the system is doing to what it should be doing, the task
of isolating a problem is greatly simplified.
Check the following items to help isolate the problem:
•
With the power switch on and system LEDs on, does the fan operate? If no, suspect
the fan or the 12-volt (V) power supply.
•
Does the system shut down after being on a short time?
— Suspect a thermal-induced shutdown.
— Ensure that the chassis intake and exhaust vents are clear.
— Suspect a power supply failure.
•
System does not boot up, but System OK LED is on: suspect the 12V power supply.
•
System partially boots, but System OK LED is not on: suspect a 5V power supply
failure.
The System OK LED should be on after the system initializes correctly. (See Figure 1.)
Note If an interface is extremely busy, the corresponding LED will be on all the time.
