AIR-AP2802E-Z-K9 Z-Domain Controller AP

AIR-AP2802E-Z-K9 is the single-unit Z-domain, controller-based Aironet 2802e. Cisco's exact lifecycle row identifies 4x4:3, CleanAir, external antennas and two Gigabit Ethernet ports. It is not the C-domain AIR-AP2802E-C-K9 or a K9C Mobility Express order.

Z-domain legal activation gate

Cisco's startup guide names this exact PID in its Brazil regulatory section and states that the equipment must not cause harmful interference to authorized systems. Verify destination approval and controller country before RF activation; preserve the chassis label and compliance result.

External antenna project

Antennas are sold separately. Record antenna PID, gain, cable loss, connector condition, mount and four RF paths. If the flexible radio is used as a second 5 GHz serving/security radio, verify the required smart-antenna/DART design rather than assuming a generic antenna kit.

Power, controller and lifecycle

Test both Ethernet links, controller join, CleanAir and radio assignment with 802.3at PoE+. Cisco ended sale on October 31, 2022 and support ends October 31, 2027; Catalyst 9120AX is a migration family, not an automatic regulatory or antenna match.
