AIR-AP1815W-D-K9 Cisco Aironet 1815W Dual-band Access Point

AIR-AP1815W-D-K9 exact wall-plate order

AIR-AP1815W-D-K9 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-K9 as the dual-band controller-based 802.11ac Wave 2 order. Record the target WLC, supported release, discovery path, entitlement and successful CAPWAP join.

D regulatory evidence

The domain letter is an ordering identifier, not a country name. For a D-domain spare, record the approved protected sites so it cannot be moved to a destination with a different domain requirement.

Treat this D-domain unit as location-controlled inventory. Name the destination or protected spare population, record who may reassign it and require a new Cisco lookup before any transfer. Commissioning should retain the controller country and enabled-channel outputs. This prevents an unused spare from appearing technically interchangeable after organizational or geographic changes.

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

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. Record whether the AP receives 802.3af or 802.3at and whether LAN 1 PoE-out is expected.

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. Test the uplink, three local Gigabit ports and passive pass-through path required by the room design.

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.

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 wireless clients and every occupied local wired port through authentication and application access.

Monitoring handover

Assign owners for AP reachability, controller join failures, radio utilization, client health and switch-port errors. Confirm that the exact serial appears in inventory and monitoring, then test the alert path. Record dashboard object, notification route and escalation owner. Telemetry that is not tied to an owned asset does not provide a reliable service baseline and will not support later comparison after channel or software changes. Monitor AP join, both radios, uplink errors, local-port state, PoE-out and representative clients.

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.

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 wireless, wired, power and client results as the operational baseline.
