AIR-AP2802E-K-K9C Cisco Aironet 2800e 4x4 MU-MIMO Access Point

AIR-AP2802E-K-K9C K-Domain Configurable AP

AIR-AP2802E-K-K9C is the K regulatory-domain 2802e Mobility Express PID. Cisco's exact retirement and secure-boot lists distinguish it from the N-domain AIR-AP2802E-N-K9C; country configuration cannot override a mismatched regulatory-domain purchase.

Country and antenna gate

Use Cisco's compliance lookup for the destination, then document controller country and chassis label together. Antennas are separate: verify four connectors, approved antenna/gain, DART or coax assembly, cable loss, mount and post-install survey.

Configurable software acceptance

Test secure boot state, certificates, image, controller election, participant join, backup and restore. Preserve the result with the serial number. Validate CleanAir, Flexible Radio Assignment and both Gigabit Ethernet paths under the target release.

Lifecycle constraint

Use 802.3at PoE+ and confirm available switch budget. Cisco ended sale on October 31, 2022 and support ends October 31, 2027. A Catalyst 9120AX migration must recheck antenna connectors, regulatory domain, software architecture and mounting.
