Interesting "lesson", Marlon:
Sometimes even the wireless enthusiasts blame the wireless
gear/technology for issues.
Sometimes it's the wired/ethernet parts of installation that cause trouble.
Sometimes it's the network (like a misconfigured VLAN or bandwidth
manager setting).
Sometimes it's lack of updated records: as in using an IP address that's
already being used but wasn't added to the IP address database records.
Good to hear you got to the bottom of it.

Finally got my strange Tranzeo issue figured out. It was a bad jumper
from the injector to the switch. Who'd have thunk it!?!?!?!?!?!
Running well for a few days now.

Subject: [WISPA] tranzeo weirdness
All-
I have the following setup that is giving me fits, (still):
350' FM tower, 25K watt FM bays up near the top, another set, 3k, down
around 220'. We have two MT backhauls w/ parabolics located in
between the FM antennas that are running fine. Down around 180' we
have a tranzeo 5AN w/ a 120 sector that's got us all fouled up. The
first radio lived fine for a couple of months then started flopping up
and down and finally died. Replaced that unit with one that stayed up
for @ 15 minutes, then locked us out, couldnt ping it either. It was
powered up, but lan light was out. Swapped in another new unit that
behaved the same. Swapped poe, AC adapters, recrimped and tested
cabling good. Tried to get into unit, still no go. We considered the
cable length as a possible problem, so we spooled off the exact cable
length needed (230') stretched it across the ground and sent
continuous pings to a new radio for @ 20 minutes with no dropped
packets. We then raised this new cable up and plugged it into the
existing radio on the tower. It would power up fine, but couldnt find
it with the discovery utility and couldnt ping it. We regrounded,
recrimped, retested everything and the stupid thing still wouldnt come
to life. So we dropped the 230' of cabling and radio back down to the
ground, powered it back up and could get right into it. It would drop
packets every now and then however. We plugged a new radio into the
cable and it ran flawlessly. I thought of pointing at the lower FM
array, but we had the same symptoms when the 3K watt station was
powered off. The cabling is all sheilded. The MT units are running
fine on the same type of cabling on the same leg. Ive considered
running the cabling in conduit and isolating the radio and radio
ground from the tower, but would like to consider anything else before
going that route. Maybe we are the victims of three bad radios in a
row? I dont want to have to shoot these radios, but they're starting
to make us pretty cranky. Any and all suggestions welcome.
Thanks,
Chris
