AIR-AP1815I-N-K9C Aironet 1815I 2x2:2 MU-MIMO AP with Mobility Express

AIR-AP1815I-N-K9C exact order identity

AIR-AP1815I-N-K9C is an indoor Cisco Aironet 1815i 802.11ac Wave 2 access point. It uses internal antennas only, supports concurrent 2.4-GHz and 5-GHz radios with 2x2 MIMO and two spatial streams, and provides one 10/100/1000 Ethernet uplink with 802.3af/at PoE.

Software order boundary

Cisco identifies K9C as the configurable order whose default software option is Mobility Express. Used stock may have been converted or reimaged, so retain the running image, current role, configured country, management backup and recovery result.

N regulatory-domain evidence

The domain letter is an ordering identifier, not a country name. For the N-domain order, retain both destination approval and controller evidence before moving the unit from staging to production.

Use the staging-to-production handoff as the N-domain checkpoint. The staging record should contain destination approval, complete PID, serial and controller country; the production owner must accept those same fields. If the AP is moved between managed sites, close the first assignment and create a new reviewed destination record instead of merely changing the location field.

Integrated antenna and installation boundary

Cisco documents two integrated 2.4-GHz antennas and two integrated 5-GHz antennas. There is no external-antenna conversion in this PID. Reconcile AIR-AP-BRACKET-8 or other selected mounting hardware and verify the final wall or ceiling placement against the RF survey.

Lifecycle decision

Cisco lists this product family as end of sale, identifies Catalyst 9105AX as the migration direction and publishes 30 April 2027 as the last support date. Available inventory does not extend that date.

Deployment evidence worksheet

Controller join evidence

Stage the access point on the controller release intended for production. Retain the controller model, software version, discovery path, authorization method and first successful CAPWAP join. Confirm that configuration download completes and that both radios reach an expected operational state. Remove any temporary staging authorization before handover. This evidence separates an orderable access point from a unit that has actually been proven compatible with the planned controller environment. For the 1815i, retain controller discovery, software download and final join evidence beside the exact serial.

Mechanical installation record

List the bracket, ceiling or wall interface, enclosure requirement, safety restraint, service clearance and cable-entry plan before scheduling installation. Receiving should identify missing mechanical items before the access point reaches site. Photograph the mounted label and final cable entry, then record how the unit can be reached for replacement. A complete electronic order can still be an unusable deployment kit when mechanical dependencies are omitted. AIR-AP-BRACKET-8 is included only when selected with the order and can be ordered separately; reconcile mounting parts.

Controlled spare policy

If purchased as a spare, name the protected site population, compatible controller image, storage location, storage conditions and periodic power-on test. Confirm that regulatory token, antenna architecture and mounting parts match the population it protects. Set a final-use review date. A stored unit can become unsuitable while untouched because controller software, country approval, certificates or network architecture may change. A spare must be proven against the protected controller image, regulatory identity, bracket and PoE environment.

Authentication path test

Commission representative clients through association, authentication, address assignment, DNS and application reachability. Preserve the identity policy used, test client type, result and relevant controller logs. An access point that joins its controller has not yet demonstrated the user path. Repeat the test after any controller, certificate or authentication-service change and retain failures separately from RF or switch-port evidence. Test association, authentication, address assignment, DNS and application reachability after the AP is operational.

Monitoring handover

Assign owners for AP reachability, controller join failures, radio utilization, client health and switch-port errors. Confirm that the exact serial appears in inventory and monitoring, then test the alert path. Record dashboard object, notification route and escalation owner. Telemetry that is not tied to an owned asset does not provide a reliable service baseline and will not support later comparison after channel or software changes. Monitoring should join AP serial, controller state, radio health, Ethernet errors and client experience.

Security baseline

Retain the approved controller policy, management authorization, certificate or trust workflow, client authentication test and logging destination. Confirm behavior on the deployed controller software instead of promising a protocol from the hardware family name. Remove temporary onboarding access and verify administrative reachability after handover. This keeps product identity separate from software-dependent security claims. Record only security settings demonstrated on the deployed controller or Mobility Express release.

Replacement dependency map

Map this unit to controller, licenses, authentication services, switch power, cable, bracket, antenna design and monitoring objects. For an end-of-sale platform, state which dependencies can be reused by the planned Catalyst migration and which require change. A nominal access-point replacement can fail when the surrounding platform was never inventoried. Keep the map with the asset rather than only in a one-time project file. Cisco names Catalyst 9105AX as the migration family; validate controller, power, mounting and coverage changes.

Fault-domain separation

Build the acceptance record so power, wired link, controller join, radio state, authentication and application reachability can be reviewed independently. Preserve timestamps and device identifiers across switch and controller logs. When a test fails, identify the failing boundary before replacing hardware. This avoids classifying a cable, policy or controller problem as an access-point defect and creates evidence that can be reused during support escalation. Use synchronized switch, AP and controller events to separate power, CAPWAP, RF and authentication faults.
