After you reboot
them, try running a continious ping every 1 minute on them or use simpleNMS.
This will prevent any issues with inactivity. Also, turn the power down as much
as you can (dial a power) without affecting your customers.
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
