AIR-AP1815I-B-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.
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.
The domain letter is an ordering identifier, not a country name. Match the B-domain carton label to the purchase line before serial assignment, then archive the dated compliance lookup.
Build the B-domain record around quotation-to-asset traceability. Preserve the authorized line, received label, chassis serial, assigned site and reviewer as one chain. If the controller later moves to another country configuration, open a new approval event rather than overwriting the original evidence; the history should explain both the purchased identity and every deployment decision.
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.
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.
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.
Measure power after the access point has joined its controller and the planned radios and services are active. Record switch model, port, negotiated power level, LLDP result and any reduced-capability warning. An idle boot result is not sufficient evidence for the deployed power budget. If an injector is proposed, verify its supported use and include its exact identity in the maintained bill of materials rather than treating it as an unspecified accessory. Cisco documents 802.3af/at PoE on the single Ethernet uplink; record the negotiated power source and boot state.
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.
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.
Record the controller release approved for this unit, the source used to verify support, the last tested date and the owner for software advisories. Available hardware does not prove compatibility with a current or future controller train. Review Cisco support information before every expansion or replacement. The lifecycle file should also state when this Aironet generation must leave service and which surrounding dependencies need migration. The Aironet 1815 lifecycle record governs software and replacement planning even when hardware remains available.
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.
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.
Define the neighboring access points and client types used for roaming validation. Record handoff behavior, interruption observed, authentication result and controller events along the intended movement path. Compare the outcome with the site's design target rather than declaring success from static association. Where this unit replaces an older AP, test both entry and exit from its cell so a local improvement does not hide a boundary problem. Roaming acceptance must identify neighboring cells, client type and controller events along the movement path.
