Input errors on FastEthernet, 1300 bridge

[kc]

I'm getting a lot of input/crc errors on the eth int for a 1300 bridge. I originally suspected a bad power injector/eth port, replaced it and I'm still receiving errors. This bridge never posed a problem before, so I doubt it is a bad cable run. There were also a lot of interface resets, line protocol up/downs before the inj replacement.

Interface resets and crc errors are almost always physical line related issues. I'd replace the cat5 and maybe reterminate the coax connections.

replaced power injector and cable, that seemed to resolve the input errors but now it's getting output errors, very high rate.
