AIR-AP1840I-T-K9: CAPWAP discovery acceptance

AIR-AP1840I-T-K9 keeps the T regulatory-domain letter and K9 controller-based identity in its complete order code. Tie the T-domain identity to the accepted channel plan and preserve the export after software changes.

For a T-domain controller-based K9 unit, verify Layer 3 controller discovery, DHCP or DNS dependencies, CAPWAP reachability and the controller software release before mounting. Capture both Ethernet ports, PoE negotiation, radio status and a client roam; do not apply Mobility Express instructions to this PID.

Evidence required before acceptance

For T-K9, collect controller discovery method, DHCP and DNS dependencies, routed CAPWAP reachability and the accepted controller software release. Add PoE, both Ethernet ports, radio state and a client roam. Exclude Mobility Express recovery instructions because this exact order is controller based.

Procurement decision

This controller-based T-domain PID should be procured with its controller and network dependencies already identified. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
