Hello. This is what happens. Recently we replaced and connected 45 new AIR-AP1852I-E-K9 APs to non-PoE switches. However, we used TP-Link Power adapter to power all APs so WLC showed "PoE/Medium Power". To solve this we bought Cisco PWRINJ6 power injectors and replaced all TP-Links and as a result, WLC showed "Power Injector/Full Power". All radios were fully working and we were satisfied. However, since that time three access points randomly reboot (3-5 times a day) and after a reboot they switch from "Full Power" to "Medium Power". There is no patter when they reboot. All 45 APs have the same firmware version. What we did: we changed a power cable to an injector, we changed the injector twice, we changed a patch cord between the injector and a switch, we used a different port on a switch, we tested the cable between the AP and the injector... all is ok, we checked the configuration of these APs on WLC, we also changed the AP. But still no joy. No matter what we change, three APs reboot. 1. Why just three APs reboot? 2. Why do they switch to Medium Power? Any Cisco expert here? Thanks for any help.

Switches cannot provide 802.3at power so we use 802.3at power injectors that should be capable of it. WLC: A command shows 15.4W. I checked logs on the AP and it says: CDP POE negotiation failed.

Hello. I have this issue. I connected many AIR-AP1852I-E-K9 and AIR-AP1852E-E-K9 (they need 20.9W) to different switches that provide 15.4W so I saw "PoE/Medium Power (15.4 W)" on WLC. To provide what my APs need I used a power injector but even after that the WLC says "PoE/Medium Power (15.4 W)". I tried three power injectors... Cisco, TP-Link and Maxi-Link. Still no joy. Any idea what is going on?

@Flavio Miranda Where? In Cisco documentation. They need more than 15.4W to be fully functional. @luis_cordova I use 30W power injector.

Hello. I need to monitor a temperature on Cisco switch via SNMP in ZABBIX. We have Cisco C2960 24TC-L. I am able to get a list of OIDs from this device using snmpwalk. How do I know which OID is the one I need? It's urgent. How do I achieve this? Thanks for any help.
