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.
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 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.
