Cisco 9166D1

 

In 6 Ghz you have to have internal antennas, using low, power and inside.   This is hard in Warehouse and Lecture Theatres

Cisco 9155D1 fixes this issue:  It is directional with internal antennas.   Fixes the issue with the ANT9103 not doing dual 4x4 5Ghz.

Upgrading Cisco DNA Sensors AIR-AP-1800S-Z-K9

 

These AP have a interesting Console cable.

You need a special cable AIR-CONSADAPT=

Best to use a POE Adaptor so you get ethernet access  for TFTP  AIR-MOD-POE

Connect to POE port to power the device and issue this command on console
