AIR-AP1815I-K-K9C Cisco Aironet 1815I WiFi 5 Mobility Express AP

AIR-AP1815I-K-K9C exact order identity

AIR-AP1815I-K-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.

K regulatory-domain evidence

The domain letter is an ordering identifier, not a country name. Tie the K-domain purchase line to the controller country configuration and the post-join enabled-channel export.

Center the K-domain package on channel-state evidence. Retain the Cisco country lookup and controller country configuration, then export the enabled-channel state after the AP joins. Store the output with exact PID, serial and survey reference. Repeat the comparison after controller upgrades so a software change cannot silently separate the live radio state from the approved order.

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

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.

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.

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.

Capacity observation

Define the expected concurrent clients, application mix, airtime utilization and channel-width assumptions for this location. After commissioning, capture radio utilization, retry behavior and representative throughput during a meaningful load period. Compare the observation with the survey design and state any shortfall. A peak link rate from a data sheet is not a site capacity result and should not replace measured operating evidence. Use measured airtime, retries and client behavior rather than a published PHY rate as site-capacity evidence.

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.

Receiving inspection

At receipt, compare model label, regulatory token, antenna form, quantity, serials and visible condition with the authorized order. Photograph labels before cartons are separated. Quarantine shortages, mixed units, damaged connectors or unapproved substitutions. Do not rely on a distributor description as evidence that the exact Cisco order arrived. Close the inspection only when every physical unit is accounted for. Receiving must verify the integrated-antenna 1815i identity and distinguish K9 from K9C software ordering.

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.

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.
