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

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)

All,

We are using the internal antenna version of the 2802 and running 8.5.135.0 on 
the WLC's.
The AP's are completely bricked/fried. No lights. We tried POE switches, POE 
injectors, and a power supply on a handful of them with no luck.

Subject: [WIRELESS-LAN] Cisco AP2800 failure rate

 

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 
spread problem.

We are running over 7700 2802i units on 8.5.131 without issue.  They have been

Were these 2802i v2? We just started installing about 300 last week.

RE: Cisco AP2800 failure rate

2018-08-16 Thread Daniel Joseph Infantino 
We have had hundreds come to us recently that were in various stages of reboot 
loop right out of the box - Cisco designed a custom patch for us because they 
claimed it was a bug with early 8.5 code. It seems to me that it must be 
something related to the hardware or the manner in which they were prepped at 
factory, because we never changed our environment.  Pre- Spring 2018 we had no 
problems with new 2802's joining. So, even though we might not have the exact 
same problem - I suspect that QA has not been wonderful on these.. Curious what 
code you are running?  Are the units bricked, or just rebooting? Cisco may be 
able to do a similar patch for you so that you don't have to RMA seventy units.

Re: [WIRELESS-LAN] Cisco AP2800 failure rate

2018-08-16 Thread Alan D Wang 
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.

No(not yet??) but we just deployed a bunch. Are you talking about the
internal antenna models or external antennas? Which software version are
you running on?
