- we have about 76 ft of thickwire with 8 transceiver connected to it. for
- the last couple of days the whole network has been going up and down. we
- ahd thought we isolated the problem to a transceiver but it keeps coming
- back.
-
- 6 of the transceivers are cabletron, the other two are dec. when the
- network is down the led's on the cabletron are receive flashing,
- transmit and collision off.
-
- i put a tdr on it and showed a short at 27 ft from one end and 70 ft
- from the other end. the connections appear to be good. the tdr is the
- only thing i have to test with.
-
- the network will stay down for about 15 minute and then come back up.
-
- any ideas about what i can look for. if i haven't been specific enough
- let me know.
