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??
