Let the record show that I’m holding back the urge to make a sarcastic

Is anyone else seeing a high rate of Cisco AP 2800 failures? Out of a batch 
of ~500 recently installed Aps, we have had roughly 70 fail. Some were online 
for a month, but some only a few days.

Typically they will fail after a powercycle or loss of power.
We are working with Cisco on this, but I’m curious if this is a more wide

You may not get link/activity until the AP's interface comes up, but the AP may 
still be requesting power and booting. I'd get one attached to a console cable 
and see what happens. If you're using a Cisco switch, the "show power inline" 
command will tell you if power is being supplied/requested.

RE: [WIRELESS-LAN] Cisco AP2800 failure rate

2018-08-16 Thread Mike Atkins

We have 1,300 Cisco 2802I access points installed on main campus and have
not noticed any issues.  If I remember correctly, our first deployment of
2802i was mid/late 2016.  I think all 80 of those access points are still
functioning today.  We have replaced a handful but those replacements have
been from water/lightning/construction damage.  We are running a mix of 8.2
and 8.3 code for different parts of campus.



Any chance your failed units are in a really high temperature area? (say
95+ for long periods of time)

Sam,
Out of the roughly 400 2802 we have, 2 have failed due to experiencing boot
room image checksum failures. The symptoms show up after a power cycle, AP
draws power but status led stays off. If you console the AP you get
nothing. Cisco has bug id CSCvf47017 in reference to this problem.
