AIR-AP1815I-Q-K9C Cisco Aironet 1815I 2x2 MU-MIMO Mobility Express AP

AIR-AP1815I-Q-K9C exact order identity

AIR-AP1815I-Q-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.

Q regulatory-domain evidence

The domain letter is an ordering identifier, not a country name. Store the Q-domain compliance result with serial, site and antenna form so return or replacement activity remains traceable.

Organize the Q-domain evidence for return and replacement traceability. Preserve the original unit's PID, approval and site, then require the replacement label and controller country to be checked independently. Link both serials to the same service case without copying the old approval blindly. This makes regulatory identity visible during an RMA rather than only during initial purchase.

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

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.

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.

Software lifecycle file

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.

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.

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.

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.

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.
