Sam, Did you have a console cable connected during power on? I found out that if you don't, you might not see the bootloader checksum error and the AP might look dead, but is actually still receiving power.

No lights. We tried POE switches, POE injectors, and a power supply on a handful of them with no luck. -Sam -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv < [email protected]> On Behalf Of Daniel Joseph Infantino Sent: Thursday, August 16, 2018 9:59 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Cisco AP2800 failure rate 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.

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. ------------------------------------------------------------- Sam Ziadeh Manager, Network Engineering & Architecture University Networking & Infrastructure Information Technology Services Louisiana State University (225) 578-0074 [email protected] <mailto:[email protected]> ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss <http://www.educause.edu/discuss> . ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
