AIR-AP1815I-S-K9 Cisco Aironet 1815I dual-band 802.11ac Wave 2 AP

AIR-AP1815I-S-K9 exact order identity

AIR-AP1815I-S-K9 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 the K9 line as a dual-band controller-based 802.11ac Wave 2 access point. Record the intended wireless LAN controller and software release, DHCP or DNS discovery path, certificate state and successful CAPWAP join.

S regulatory-domain evidence

The domain letter is an ordering identifier, not a country name. Compare the complete S-domain PID on quotation, carton and asset record; family equivalence is not regulatory equivalence.

Make quotation accuracy the S-domain control. The approved quote, supplier confirmation, received carton and asset record must carry the complete same PID. A substitution request should identify antenna form, controller-image state and regulatory token separately. Only after destination approval and controller review should the replacement line be accepted, even if pricing and lead time are unchanged.

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.

Ethernet and cabling proof

Preserve the permanent-link test, patch-lead identities, switch port, negotiated Ethernet rate and error counters. Investigate pair faults, excessive length or rate fallback before wireless acceptance begins. A link light only proves connectivity at some rate; it does not demonstrate the intended uplink performance. Tie the cable result to the AP serial so a later throughput problem can be separated from radio, controller and wired-path causes. The 1815i requires a Gigabit Ethernet link to avoid a wired bottleneck; retain negotiated rate and cable counters.

Survey-to-install reconciliation

Attach the approved RF survey location, mounting height, orientation, expected client density, channel width and neighboring-radio assumptions to the order. After installation, compare measured coverage and interference with that design. If ceiling construction, antenna placement or obstructions changed, document the deviation and repeat the affected measurements. This provides a site-specific acceptance reason for the exact unit instead of relying on a family data sheet alone. The integrated-antenna result depends on wall or ceiling position, orientation and the accepted RF survey.

Country approval retention

Save the Cisco compliance lookup result, lookup date, deployment country, approved regulatory token and reviewer. If the destination changes, stop and repeat the approval rather than moving the unit on the strength of an earlier purchase. Compare the controller country setting and available channels with the retained evidence. Regulatory eligibility is a deployment condition and cannot be inferred from connector fit, stock location or a similar-looking part number. Cisco makes the customer responsible for country approval; save the compliance lookup and controller country.

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.

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.

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.

Operational log retention

Store the initial controller events, switch-port state, radio assignment, channel list and client test results with a consistent asset identifier. Define how long commissioning evidence is retained and who can retrieve it. A later firmware, controller or RF change should add a new dated observation rather than overwrite the original. The resulting history supports lifecycle decisions and distinguishes a new regression from the accepted baseline. Keep the first accepted power, wired, radio and client results as a baseline for future changes.
