Hi Guys,
I have 42 wireless APs (cisco AIR-CAP3702E-E-K9). All the APs getting rebooted time to time without any pattern. The last rebooted reason showing as "Power loss".
LKKURXA157 uptime is 1 day, 10 hours, 53 minutes
System returned to ROM by power-on
System image file is "flash:/ap3g2-k9w8-mx.153-3.JF10/ap3g2-k9w8-xx.153-3.JF10"
Last reload reason: Power Loss
Until now, we have done several things to resolve this issue. Until no any improvement.
1. Upgraded to latest recommended version.
2. To isolate the power issue we have Installed a PoE switch to provide the PoE power to one AP (earlier all the APs powered up with power injector).
2. Monitor the states of the selected POE powered AP , Observed that AP also showing last reboot reason as "Power Loss". But PoE switch has good uptime.
3. Enabled the AP core dump feature. But there is no any crash logs.
These are the logs generated from APs.
