AIR-AP1815I-C-K9Cisco Aironet 1815I Dual-band 2x2:2 MU-MIMO AP

AIR-AP1815I-C-K9 exact order identity

AIR-AP1815I-C-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.

C regulatory-domain evidence

The domain letter is an ordering identifier, not a country name. Preserve the C-domain destination approval with the exact PID, serial and controller country so a nearby domain cannot be substituted silently.

Use final receiving approval as the C-domain checkpoint. Match the authorized quotation, carton label, chassis serial, destination and controller country before release. Preserve the dated Cisco lookup with those fields. A later replacement or site transfer must create a new decision rather than inheriting the old location's approval from the asset record.

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

Power-state acceptance

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.

Serial-level asset control

Capture chassis serial, base MAC address, carton reference, deployment site, controller assignment and asset owner. Reconcile the identifiers against the purchase line before activation. Multi-unit cartons require an entry for every physical access point; a carton SKU alone cannot show which unit was installed, held as a spare or returned. This record is also needed to trace support entitlement, replacement history and monitoring ownership. Link serial, base MAC, installed location and controller or Mobility Express ownership before activation.

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.

Roaming acceptance

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.

Interference baseline

Preserve the pre-install and post-install noise, neighboring-radio and channel-occupancy observations for the selected location. Record any controller-driven channel change during acceptance. If the regulatory profile limits the channel choices, state how that constraint affected reuse and mitigation. This baseline gives future troubleshooting a reference point and prevents an unrelated interference change from being attributed to the hardware order. Preserve active country and legal channel state after controller changes or a Mobility Express conversion.

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.

Handover completeness

The handover package should include exact order identity, destination approval, serial record, controller evidence, switch port, mounting or antenna record, user-path tests and named operational owners. Review the package with the receiving team and list unresolved exceptions. A unit is not operationally accepted when important evidence remains only in installer notes, email attachments or an unowned temporary dashboard. Handover should include exact PID, serial, compliance lookup, software role, mounting record and lifecycle owner.
