APs Hardware faulty very frequently

[manvik]

We have AP 1850 series APs deployed in the campus, around 300 APs. All those are connected to Cisco POE switches.

Every day at least 2 APs becomes hardware faulty, they don't even power on.

All APs are new one, maybe 1 year old.

Any method to identify why the APs getting faulty everyday. Does Cisco assist in such cases.

What PoE switches, i have noticed some issue like this 3700 AP connected 3750swithes. (no solution found other than replacement).

@Rich R have previously observed that the 1800 have a high failure rate. 

I would recommend contacting TAC and organize to get them RMA-ed before EoL date.

[Rich R]

That’s right we’re averaging between 20 and 30 RMA for 1832s every month, and have been for more than a year already. We have many other APs that are older that don’t have failure rates even 10% of that so it’s much higher than normal. Rest assured that Cisco know about this but they decided a field notice was not required and to replace on failure by standard RMA process.

Thanks for the info. 

Cisco does not want a "repeat" of the Memory Component Issue & the Clock Signal Component Issue.

I thought the support for hardware replacement under lifetime warranty  is till end of HW support date and not end of life date, is that not correct ?

Read the Terms & Conditions of the Cisco Limited Lifetime Hardware Warranty properly and carefully.

[Rich R]

It does say "Cisco hardware warranty support will be discontinued on the Last Date of Support (LDoS) published in the product End of Life Announcement" so I think you're right @ammahend 

[Leo Laohoo]

No.  The End-of-Life date is what is followed.  
I RMA 3750X up to the End-of-Life date.

[Rich R]

"End of life" simply refers to all the milestone dates in the EOL/EOS notice. For 3750-X:

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3560-x-series-switches/eos-eol-notice-c51-736139.html 

which means the "Last Date of Support:HW" was 31 October 2021 so you should have been able to RMA those until that date?

[ammahend]

I will verify that with Cisco SE, if EOL is true then what does it even mean having and end of hw support date, it’s not that TAC can fix a hardware issue.
