AIR-AP1815W-T-K9C Cisco Aironet 1815W Dual-radio Mobility Express AP

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

AIR-AP1815W-T-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.

T regulatory evidence

The domain letter is an ordering identifier, not a country name. Document the T-domain destination and controller country setting before installation, then keep the evidence through software upgrades.

Use software-upgrade governance for the T-domain record. Before an upgrade, preserve the controller country, enabled channels, AP serial and dated compliance lookup; after the change, capture the same fields for comparison. Investigate a changed radio state before production acceptance. This ties the domain decision to an observable configuration history instead of a one-time purchasing note.

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.

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. Reconcile AIR-AP-BRACKET-W3, the Torx screw and any AIR-AP1815W-KIT spacer or jumper.

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.

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.
