AIR-AP1840I-B-K9: Inventory transfer control

AIR-AP1840I-B-K9 keeps the B regulatory-domain letter and K9 controller-based identity in its complete order code. Treat the B-domain order as destination-specific inventory and repeat compliance review before any reassignment.

The B-domain K9 unit should remain tied to its destination approval throughout inventory transfers. Before replacement, export the existing AP configuration and switch-port state. After join, verify both radios, both Ethernet interfaces, authentication and monitoring labels so the new serial does not silently inherit incomplete records.

Evidence required before acceptance

Before moving B-K9 inventory, export the existing switch-port and controller state and retain the destination approval. After replacement, verify both radios, both Ethernet interfaces, authentication and monitoring labels. Close the transfer only when the new serial is linked to the new acceptance evidence.

Procurement decision

Inventory mobility does not remove the B-domain restriction; each destination change requires fresh evidence. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
