Gating does not work and the message The PAC does not respond Due to The PAC Fiber Optic Cable's Transmit and Receive Lines Transposed (Connector Reversed).
Symptom
Gating does not work and the message The PAC does not respond displayed during system boot or TPS reset. This problem was found while installing this new system. Ran Diagnostics --> Peripherals --> PAC Diagnostics --> PAC Power up Test and SPU-->PAC Loop back Test, both of which failed with error codes 2254702 & 2254703. Measured PAC power at rear of SSM module and found it to be okay. This problem was found while installing this new system.

Error message
2254703 SPU TO PAC LOOPBACK FAILED. The SPU did not receive data back from the PAC during the SPU to PAC loopback test. Incorrect count of data received 0. Data count expected 8 --> Extended Error: The SPU did not receive data back from the PAC during the SPU to PAC loopback test. Incorrect count of data received. %d. Data count expected %d. Possible cause(s): PAC 2254702 PAC DIAGNOSTIC TIMEOUT. The PAC did not return a result to the SPU for the last PAC diagnostic test in the allotted 8 second time. Try running PAC datapath tests or other PAC diagnostics. Extended Error: Verify that the PAC module has power. Run SPU-->STIF and SPU-->PAC loopback tests to see if the MGD chassis can talk to the PAC module. Check fiber optic connections between the STIF and the PAC. Possible cause(s): PAC 2225935 The PAC does not respond. Check PAC power and fiberoptic connections, run PAC diags. 2225935 The PAC does not respond. Check PAC power and fiber optic connections, run PAC diags. This error condition adversely affects gated scans only. 2225935 The PAC does not respond.
