Cisco Cisco Aironet 1522 Lightweight Outdoor Mesh Access Point Troubleshooting Guide

PoE from the switch or router is enabled.

Connections are generally erratic 
or inconsistent.

1) Verify that the PoE port on the switch 
or router is disabled by checking the PoE 
LED or configuration with the CLI. If the 
LED is continuous or fluttering, disable 
PoE on the port.

Cisco mesh access points (1500 
Series) are not compliant with 
802.3af, which allows an access 
point to take power from a switch 
or router. PoE must always be 
disabled on the switch or router 
associated with the AP.

Cisco external power injectors are 
mandatory for PoE 
configurations.

2) Verify that the recommended distance 
(< = 128 ft) between the switch or router 
and the PoE injector is not exceeded.

Duplicate IP addresses on the access 
point.

Connections are generally erratic 
or inconsistent.

1) Reconfigure the access point by 
removing the static IP address, if 
applicable.

2) Have DHCP server assign the access 
point IP address. 

Ensure that the DHCP server is 
configured and accessible on the 
same subnet as the access point.
