Boot Up and Initialization
Potential Problems During Boot Process
It should be noted that the FAULT_L status line can also be triggered by an
over voltage or an over temperature condition in the A6 Power Supply
assembly.
Is the FAULT_L LED on? (Test Point 508 at a TTL low level)
If not:
Replace the A6 Power Supply assembly.
If yes:
Remove different assemblies from the instrument one at a
time to see if one of them can be identified as overloading
the A6 Power Supply assembly.
If, when a particular assembly is removed, the power
supplies will now come on, replace that assembly.
If no assembly can be found that is causing the overcurrent
condition, replace the A6 Power Supply assembly.
