Model 3096RC T-DAC Getting Started Guide 

5 • Troubleshooting and maintenance

Fault analysis

The following procedures outline steps you should follow when troubleshooting a Model 3096RC 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.

Power is being applied. No action recommended.

Flashing The 3096RC has detected a power failure on a power bus. There 

may be a problem with the CPCI power supply system such as a 
failed power supply module in the chassis. The Model 3096RC 
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 chas-
sis power supply module is installed in the chassis and func-
tioning normally.

CPU FAIL

CPU is unable to load the software from FLASH to RAM for 
operation. As soon as possible, remove the Model 3096RC 
from the CPCI chassis, wait 30 seconds, then re-insert the 
Model 3096RC into the CPCI chassis and see if the problem 
disappears. If the CPU FAIL LED remains lit after the Model 
3096RC 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

Flash-

ing

The Model 3096RC is operating normally. No action rec-
ommended.

Off

The Model 3096RC is not functioning properly. As soon 
as possible, unplug both power cables from the Model 
3096RC, wait 30 seconds, then plug the cables back 
into the Mode 3096RC to see if the problem disappears. 
If the SYSTEM LED remains lit after the Model 3096RC 
completes the power-up cycle, contact Patton Technical 
Support to determine whether the T-DAC needs to be 
replaced.
