We are scrambling to get a spare (circumstances were origianlly going to give us a spare set, but didn't work out that way) because I *think* I have one end of my PTP800 link dying. I'll have everything go down on the far side, but if I log into the near side (ethernet) I can reboot the radio and then it establishes link right away. In the last 24 hours we've had it happen three times. Techs checked the far end and found a bad rectifier in the DC plant so we were excited that was the cause, but it just happened again.
Logged into the near side I'm seeing a few syslog messages that are making me wonder if the near side is failing:
status; RFU Tx Mute Status; was=Muted Due To RFU Fault; now=Transmitting;
status; RFU Tx Mute Status; was=Muted Due To Inactive; now=Muted Due To RFU Fault;
status; RFU Cable Attenuation Adjust Alarm; was=IF Cable Attenuator Adjusting; now=OK;
status; RFU Cable Attenuation Adjust Alarm; was=OK; now=IF Cable Attenuator Adjusting;
status; RFU Cable Alarm; was=IF Cable Voltage Out Of Range; now=OK;
status; RFU Cable Alarm; was=OK; now=IF Cable Voltage Out Of Range;
My techs are on their way up to the near side now to check all cabling, but wondering if anyone else has experienced this or any other trouble shooting ideas? Does it sound like it is the near end failing? I don't see anything nearly as interesting in the syslog of the far end.
