Model 3196RC T-DAC User Manual	5 • Troubleshooting and maintenance

Fault analysis

The following procedures outline steps you should follow when troubleshooting a Model 3196RC malfunction.

1.If possible, talk to the person who filed the trouble complaint and determine the operational symptoms. Record the symptoms on the appropriate trouble report form (include the front panel LED indications).

2.Refer to table 8 for LED definitions and compare the recorded results from the trouble report against those in the table, then refer to the section recommended in the table for the maintenance procedure that will repair the malfunction.

Table 8. LED definitions

LED	Location	Color	Status	Meaning

POWER	Front	Green	On	Power is being applied. No action recommended.
	panel		solid
			Flash-	The 3196RC has detected a power failure on a power
			ing	bus. There may be a problem with the CPCI power sup-
				ply system such as a failed power supply module in the
				chassis. The Model 3196RC will function normally with
				one power supply. Inspect the power supplies in the CPCI
				chassis to identify and replace the failed power supply
				module. If the POWER LED continues flashing when all
				chassis power supplies are functional, contact Patton
				Technical Support to determine if the T-DAC should be
				replaced.

			Off	No input power is being applied. Verify that at least one
				chassis power supply module is installed in the chassis
				and functioning normally.
CPU FAIL	Front	Red	On	CPU is unable to load the software from FLASH to RAM
	panel		solid	for operation. As soon as possible, remove the Model
				3196RC from the CPCI chassis, wait 30 seconds, then re-
				insert the Model 3196RC into the CPCI chassis and see if
				the problem disappears. If the CPU FAIL LED remains lit
				after the Model 3196RC completes the power-up cycle,
				contact Patton Technical Support to determine if the T-
				DAC needs to be replaced.

			Off	The CPU is operating normally. No action recommended.
ALARM	Front	Red	On	A minor alarm condition has been detected.
	panel		solid

			Flash-	A major alarm condition has been detected.
			ing
			Off	The Model 3196RC is operating normally. No action rec-
				ommended.
