AIR-AP1840I-A-K9 keeps the A regulatory-domain letter and K9 controller-based identity in its complete order code. Keep the A-domain authorization, full carton PID, serial and configured country in one commissioning record.
For A-domain K9 commissioning, separate regulatory evidence, controller discovery and RF acceptance. Match the complete PID and serial, record country and enabled channels, validate internal-antenna placement, then test client service at the survey locations. Archive the controller revision used for the result.
The A-K9 commissioning pack should connect the authorized PID and serial to country selection, enabled channels, internal-antenna placement and survey-location tests. Keep controller discovery and RF acceptance as separate checks so a successful join does not conceal a placement problem.
The A-K9 order is complete only when regulatory, controller and RF evidence point to the same installed asset. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
