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??
