This does not pertain to your problem. Haveing an average UPS
does not eliminate spikes, surges and some sags. Only ones labled as power
conditioning UPSs do that (and the cheaper one don't do it that well).
When the average UPS is not on battery backup it acts just like a surge
supressor and must be rated to handle the level of noise on your power
lines.
Just an FYI
TO SMARTBRIDGES - Has any testing been done to see how a non-sine
wave AC source affects the units? Most UPS produce a modified square wave
or sawtooth AC wave and not a pure sine wave.
Kinda sounds like something I came across a few weeks
ago....
Here on my desk, I have a aPP. It's always up and running,
plugged into a UPS and a network that has everything on a UPS. (so no
surges anyplace) Anyway, I upgraded the firmware several several
weeks back. (forget when exactly). I got home, plugged in my laptop,
slamed in my wireless card... and went no where. I associated just
fine, but I couldn't pass any packets.
I got into simpleMonitor and looked at the ethernet stats, and it
shows packets being sent and recived. I reboot the AP...
reassociate... and it passes 3 packets, then dies... I went aroun
and around with it with reset's, fact resets, fw reloads... etc etc... for
about 2 hours.
And after messing with it that long, I finally got it to work
again. Kinda screwy if you ask me... something that's been sitting
here working for that long then all of a sudden does
that...
Well…thought I would keep everyone posted on my
numbers.
As
of last weekend, we went from 30 to 45 units off a single aPPo. I
actually have 30 units directly off my head-end aPPo (one of which is
the repeater) and 15 more off the repeater. The latest 15
are all airBridges. We are pulling about 1.2 Gig per day through
the head-end (500 meg of which is from the repeater
clients).
1.
I did the bulk update with the
latest simpleNMS and changed RTS/CTS and FRAG to 1496 and
100
on all client units (not head-end). This was a
pretty cool feature. However, twice within 1 day ALLLL my units
lost association and I had to reboot my head-end aPPo to get them
back. So…needless to say, I changed the RTS/FRAG settings back to
default. No problems since.
2. I used simpleDeploy to burn ALL new customers. I
then hot tested them for a minimum of 24 hours prior to deployment with none of them blinking an
eye. Out of the 15 deployed, I have 3 units that are losing
association and not getting it back. I have had the customer do a
power reset by pulling the plug, factory default reset, etc,
etc….but no luck. Oddly enough, one of the 3 units just came
back online this morning with no assistance. Pretty darn
flakey! Note: all the units could be pinged from the wired
side and logged into (but DEAD on the wireless
side). Now I am going to go do some climbing and
replacing.
Side Note: My head-end aPPo which has been online since Dec
25th 2003 is going down hill quick. The symptoms
are this:
1.
About 3-4 times a
week, the unit becomes unresponsive on the Ethernet side while still
passing traffic (hard reboot).
2.
The RTS/FRAG
thing mentioned above really had
me shaking in my
boots (reset to default).
3. I have been working with sB for a while on this
flakey aPPo, and I am now struggling with EC to get a replacement unit
before this one dies.
I
think that sB is awesome. They are VERY responsive and have even
phoned me personally to resolve issues. All my units previously
deployed are working wonderfully. 3 out of the latest 15 have
not. That doesn’t look good, but I am sure they
are getting to the bottom of it. Maybe it is a bad
simpleDeploy release??
