Do NOT rule out power. It could be a little too high or
a little too low and MOST ups units won't compensate for that.
Also, if there are large pumps there it's quite likely that
you are getting intermittent brownouts that the unit won't quite kick in
for.
See if a local electrician has a voltage recorder. We
saw many VERY strange copier problems caused by power issues.
It seems VERY strange that FOUR units would all do the same
thing at the same time. I've used 3 or 4 of them of late and had NO bad
ones. Only a dead eithernet port but that happened after a wicked
lightning storm and we also lost a computer nic card on that same system so I'll
not blame sb for this one.
I'm home if you want to call and talk about some of
this. The office line rings here too.

It just keeps getting better. Now three of them are
down, which means only one is up. We know for sure now that it is not
the POE, the power supply, or the radio, unless the one I got in as a
replacement has the same problem as the one it replaced, which is highly
likely. Either all the APPOs have the same problem, including the ones
that are still shipping, or we have some kind of weird power problem.
Since everything is plugged into a UPS, I don't see how it could be power, but
I am not ruling out anything at this point. Now I just have to try
and convince the only tech on duty tonight to climb the water tower
again. This makes six nights in a row that he has had to climb that damn
tower. I know, I know we should have designed it with things on the
ground, but we didn't know we were going to have this much trouble with the
equipment, and we were trying to make the city happy and keep everything as
unobtrusive and out of sight as possible. It is too late to redesign the
whole system, we don't have the money to start all over.

Get a couple of 100' high grade extension cords. Put
your ups unit on the ground and when you need to reboot them just pull the
plug for 10 seconds.
Not a good fix but better that what you have till we
figure out what to do about the ap's....

Marlon,
My AC runs up the water tower from a breaker at the base
of the tower. There is an AC outlet in my NEMA box with the UPS
plugged into it, a power strip into that, with all the power supplies and
the D-Link switch plugged into that. All the cat-5 is outdoor rated,
shielded and gel filled, all cables tested with a cable tester after being
built up on the tower. As for lightning arrestors, we haven't had
any sign of lightning or a drop of rain in months - this is north Texas
where rain doesn't exist from June until October. I don't see how I
would run a power cord down the tower, it just doesn't seem
possible. We can try moving the cat-5 cables around to different
ports on the switch to see if it is one port on the switch that is
failing, but since we have had two different units fail now with the same
exact problem and they are on different ports, I don't think that would
tell us much.
Any more ideas - I am always willing to listen and try
different things,
Gloria

First off, run a power cord to the bottom of the tower
for a bit so you can just unplug it to reset everything
;-).
If multiple units are seeing failed eithernet ports
you might need to look at your switch. Also, might want to make
sure you have good lighting arrestors on the cat 5 ports.
In almost 4 years of this wisp stuff I've only lost a
couple of ethernet ports and both of those were at the same place and on
the same linksys cable router.
Until this fall. We lost two sb radios with dead
ethernet ports durning a storm. One ap and one client. At
one location the homeowner also lost the ethernet port in the dell
computer. At another location all radios are fine but the customer
lost a nic in a dell computer.
I'm thinking that there may be some crappy ethernet
ports on the market?

Marlon,
I don't have any spares here. The only extras
I have are the one we took down night before last that we thought was
bad, and an indoor that was sent to me instead of an
outdoor.
We replaced the POE with a known good one on
Wednesday night, we replaced the radio itself Thursday night, and
replaced the power supply last night. So far it is up, but it
usually takes about 24 hours for it to go down.
Now a different one is down - same problem - dead
Ethernet side, can't talk to it. This is the first time this one
has gone down since we put them up three or four weeks
ago.
If you have any more ideas, let me know. I am
willing to try anything at this point, if my techs don't quit because
they are sick and tired of climbing the water tower every night to
either reset something or replace something.
Thanks for your help,
Gloria

You have other ones there right?
First, swap ethernet ports on the switch.
Swap power supplies and then power injectors (I just had a bad power
shot) with a known good working unit.
If none of that works, swap the ap with a known
good working unit. If the problem moves, yep, really bad
luck! If the problem stays with another radio, it's
environmental.
I know when we first got started we were on one
end of a 30 mile ptp wmux link. It would totally shut down my
radio. Similar to what you are seeing.
Call me and let me know what you find or if you'd
like to talk about this a bit more.
*Time to learn those trouble-shooting techniques
;-)*

with APPO problem
Anyone got suggestions as to what is causing one
of my APPOs to go down? We have had to climb the water tower
and reset it three times in the last week. We replaced the
POE on Wednesday and it went down again Thursday. I ordered
a new unit overnighted and replaced the unit last night. It
worked great all day today, but is down again now. The
outdoor rated cat-5 run is only about 20 feet, the cable was
tested with a cable tester before putting it in place, everything
is water proofed (even though we haven't had rain in
months). What else is there? The POE was replaced, the
entire unit was replaced, and we still have the same exact
problem. When it does this, the Ethernet LED is off, the
Power and TXRX LED is on solid, and we have no communication with
it. Did I get so lucky as to get two bad units with the same
exact problem? The only item that has not been replaced is
the power supply - could that be bad? All the other units on
the water tower are working fine since I upgraded the firmware
last Sunday. They are all plugged into the same switch,
which is plugged into a UPS and all of it is in an air conditioned
NEMA box.
smartBridges tech - or anyone -
help!
Thanks!
Gloria
