Problem Clarification

Error Type 513: ring generator operational status failure. Aux Data values give description:

                           Aux 2: Shorted

                           Aux 16: When redundant power supplies are present, the standby ring generator (slot 15) is providing ringing voltage.

Error Type 257: ring voltage not detected on backplane.

Error Type 1: ring generator interchange failed. Run test environment long. Run test board long. Follow the repair procedures.

 

Error Type 1793: Power supply operational failure. Aux 4: Failure, voltage, temperature, or internal status fault.

Error Type 513: the +5V is out of tolerance (4.75 to 5.25 V (+/- 5%)).

Error Type 769: the -5V is out of tolerance (-4.5 to -5.5 V (+/- 10%).

Error Type 1025: the -48V is out of tolerance (-44.2 to -51.8 V (+/- 8%)).

Error Type 2049: input power failure.

Error Type 2305: aux sig lead failure.

Error Type 513: Ringing Application Test (#48) failure. The terminal equipment is not connected to the circuit pack.

 

 

Cause

One power unit was switched off.

Solution

Need to check your electrical network, fuses, etc., and verify if proper grounding has been applied.
