AIR-AP1815W-Q-K9C Cisco 1815W MU-MIMO WiFi 5 Mobility Express AP

AIR-AP1815W-Q-K9C exact wall-plate order

AIR-AP1815W-Q-K9C is a compact Cisco Aironet 1815w access point for wall or junction-box installation in hospitality, residence and multi-dwelling environments. It supports concurrent 2.4-GHz and 5-GHz 2x2 radios with two spatial streams and integrated antennas.

Software order boundary

Cisco defines AIR-AP1815W-x-K9C as the order whose default software option is Mobility Express. Used inventory may have been reimaged, so preserve running software, current role, configuration backup and recovery evidence.

Q regulatory 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.

Room-side Ethernet and PoE boundary

The 1815w provides one Gigabit uplink, three local Gigabit Ethernet ports and one passive RJ-45 pass-through path. LAN 1 can provide 802.3af Class 0 PoE-out only when the AP itself receives 802.3at; there is no PoE output when the AP receives 802.3af.

Mounting and antenna boundary

The unit uses integrated dual-band antennas with approximately 2 dBi peak gain at 2.4 GHz and 3 dBi at 5 GHz. It installs vertically with AIR-AP-BRACKET-W3; AIR-AP1815W-KIT is a separate spacer and RJ-45 jumper option when the cabling path requires it.

Lifecycle decision

Cisco lists the Aironet 1815 family as end of sale, publishes 2027-04-30 as the last support date and identifies the Catalyst 9105AX Series as the migration family. Existing stock does not extend that support date.

Room 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 1815w, retain controller discovery, software download and final join beside the exact serial.

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. Tie coverage results to the vertical wall or junction-box position and integrated antenna orientation.

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, room, controller object and local wired-port assignments before activation.

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. Save a dated Cisco compliance lookup; successful radio operation does not establish country approval.

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 1815w generation must leave service and which surrounding dependencies need migration. Apply the 1815 Series lifecycle to software, support and Catalyst 9105AX migration planning.

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. Prove a spare against the protected controller or Mobility Express image, bracket, PoE and port design.

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 identify the wall-plate 1815w and distinguish K9 from K9C before staging.

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, controller and wired-client events to isolate room-service faults.
