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??
