AP 1832i Failure

jdparsons — Fri, 06 Jan 2023 17:05:59 GMT

We have seen a very high failure rate for the AIR-AP1832i-B-K9 recently with no known cause. Some displayed a solid amber led and others displayed no led.

After swapping out the AP with a spare, the spare comes online right away. Some just go down and some have the below error. For the latter we have used TDR (sample below). Again though when we put a different AP in its place it comes up.

We have also tried plugging it directly into the switch and on a different port.

Any ideas? Are these APs just borked?

Also, does the Cisco lifetime warranty cover this? This part of the restrictions is a bit confusing "Cisco Systems, Inc., or the Cisco Systems, Inc. subsidiary selling the Product ("Cisco") warrants that commencing from the date of shipment to Customer (and in case of resale by a Cisco reseller, commencing not more than ninety (90) days after original shipment by Cisco), and continuing for a period of the longer of (a) ninety (90) days or (b) as otherwise set forth at https://www.cisco.com/go/warranty, the Hardware will be free from defects in material and workmanship under normal use." Is it lifetime or 90 days from shipment?

Thank you for any support/answers in advance!

- Check if the AP(s) get sufficient (POE?) power , also connect to it and just after boot issue the command show logging , watch for anomalies in the logs ,

Thank you for the response.

I don't think power is the issue especially since when we put a different AP on there it comes up perfectly fine. The power drawn at 15.4 W is pretty standard from my experience it is typically that or 17.9 W. The vast majority don't even have a led light lit up and the solid amber ones just stay that way and don't boot. I've read on some threads that there is a pretty high failure rate for the 1832i. I requested the MTBF from Cisco, after support played musical chairs for awhile. Still waiting on that.

RMA the faulty APs while it is possible -- The 1800 are covered under Limited Lifetime Hardware Warranty.

@Rich R has reported that a number of 1800 failures and I suspect the failures are due to the low quality of the components being used.

That's right Leo - we RMA at least 20 x 1832 per month due to hardware failure.
Cisco wireless BU is aware but say this is still below expected MTBF so they will not issue a field notice about it and you should continue to replace on failure.

we have 38 X 1832i all from 12/2017. Since last month, 11 of them are dead: no more LED, no reaction even when connecting to different POE switches. Same issue with 9 X 1832i from 04/2021: 4 of them are dead: no more LED. On the port where the 1832i no longer worked I have connected another identical: immediate response.
