- I have had a heck of a time getting repair service for some Ethernet
- drops which were provided a long time ago without any equipment to plug
- them into. Now the computers start showing up, and about a fourth of
- the drops are dead, mostly because the stupid transceiver cables have
- pulled loose from the transceivers.
-
- I'm under strict orders not to go messing around where the transceivers
- are, primarily because of a recent on-the-job injury I sustained doing
- something similar. (You *don't* want to know about it.) Also, our
- repair guys are scum (there, I've said it) and won't come over unless I
- issue paperwork calling for a new installation.
-
- I'd like to not have to pay these crooks for reinstallation of what
- they didn't do right the first time, but as I have no choice, it would
- be good to know which drops are going to work and which aren't.
-
- Is there any simple way I can test to see if a transceiver cable is
- connected to a transceiver from the computer end of the cable? Some
- sort of ohmmeter check, maybe? I don't have a computer I can roll
- around to every location, unfortunately.
-
- A few of these drops come from Cabletron MT-800 8-to-1 multiport
- transceivers. I need to take this into account, too, because I don't
- know which drop goes to which type of transceiver. The individual
- transceivers draw power from the computer, but I don't think that's
- true of MT-800 type devices.
