AIR-AP1815W-Q-K9 Cisco Aironet 1815W 802.11 a/b/g/n/ac Access Point

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

AIR-AP1815W-Q-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.

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

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.

Quotation substitution gate

Compare antenna form, regulatory token, configuration suffix, pack quantity and complete Cisco part number on the authorized quotation. Treat any changed token as a substitution that requires a new technical and regulatory review. Procurement should not accept a nearby Aironet 1815w line merely because the family name matches. Preserve the approved line, received label and exception decision so the final asset can be traced to the exact order reviewed here. A changed domain letter or K9/K9C suffix is a different 1815w procurement identity.

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.

Security baseline

Retain the approved controller policy, management authorization, certificate or trust workflow, client authentication test and logging destination. Confirm behavior on the deployed controller software instead of promising a protocol from the hardware family name. Remove temporary onboarding access and verify administrative reachability after handover. This keeps product identity separate from software-dependent security claims. Record only security functions demonstrated on the deployed controller or Mobility Express release.

Capacity observation

Define the expected concurrent clients, application mix, airtime utilization and channel-width assumptions for this location. After commissioning, capture radio utilization, retry behavior and representative throughput during a meaningful load period. Compare the observation with the survey design and state any shortfall. A peak link rate from a data sheet is not a site capacity result and should not replace measured operating evidence. Use measured airtime, retries, wired load and client performance rather than headline PHY rate.

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.

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 PID, serial, room, compliance result, software role, cabling and lifecycle owner.
