CISCO AIRAP1852I-KK910C Aironet 1850 Series Access Points

AIR-AP1852I-KK910C exact order identity

AIR-AP1852I-KK910C is a 1852i indoor access point with integrated omnidirectional antennas in the Cisco Aironet 1850 Series. This exact SKU combines regulatory-domain token K with a configurable K910C ten-access-point pack. The platform is a dual-band 802.11ac Wave 2 access point with four 5 GHz spatial streams in single-user operation and three in multiuser operation.

Antenna and environmental boundary

Cisco rates the internal antenna system at 3 dBi for 2.4 GHz and 5 dBi for 5 GHz, with 360-degree horizontal beamwidth. No external antenna is selected by this SKU. Preserve enclosure orientation, bracket, mounting height and post-install coverage because placement determines how the integrated pattern is used.

Order and controller boundary

K910C combines a configurable order with ten physical access points. Domain selection and physical quantity are independent acceptance gates. Preserve the configured-domain evidence at carton level and create ten serial-level rows. Quarantine partial, mixed-domain or unconfigured receipts.

K regulatory-domain evidence

Cisco lists this profile as 2.4 GHz channels 1-13; 5 GHz blocks at 5.180-5.320, 5.500-5.620, and 5.745-5.805 GHz. The K profile has three separated 5 GHz groups, with narrower middle and upper limits than several neighboring profiles. Those boundaries must be reflected in controller and survey records. Verify all three channel groups and their upper limits after the AP joins the controller. Retain the output with the K-domain purchase line so a broader template cannot be mistaken for compliance.

Procurement inference: three separated groups with distinct upper limits make boundary verification more important than a simple channel count. The acceptance package should list each enabled group and compare it with the K-domain survey. If the controller aggregates the output into one display, export a detailed channel list for evidence. Recheck those boundaries after controller migration or country-setting changes.

Power and interface boundary

The 1852 provides a PoE Gigabit uplink and a Gigabit AUX port for link aggregation. Cisco states that 802.3af disables AUX and USB on both antenna forms and reduces the 1852e 2.4 GHz radio from 3x4 to 2x3. Record negotiated power before promising the complete interface and radio state.

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. The 1852i and 1852e have different operating-temperature ranges, and an external-antenna deployment also requires a complete cable and mounting bill of materials.

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. If the product came from a ten-unit pack, the 1852 carton identity must be expanded into ten individual records before support, return or replacement handling.

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. Cisco ended 1850 Series software maintenance in 2023, so controller compatibility evidence is especially important for inventory purchased late in the lifecycle.

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 1852 must be checked against the protected controller release, certificate behavior, regulatory domain, antenna form and 2027 support cutoff before assignment.

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. The 1852 domain table varies materially by token, so preserve interference observations against the exact enabled-channel list rather than a generic country template.

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 controller, switch and client timestamps to separate a PoE/AUX limitation, CAPWAP issue, RF condition and authentication failure before declaring a hardware defect.

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. Preserve the original 1852 controller join, power mode, AUX state, channel list and client tests so later changes can be compared with an accepted baseline.

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. The final handover should include the exact PID, regulatory approval, serial, antenna or mounting record, power mode, both Ethernet interfaces and lifecycle owner.

Lifecycle decision

Cisco ended sale of the Aironet 1850 Series on 1 May 2022, ended software maintenance on 1 May 2023 and lists 30 April 2027 as the last support date. Cisco identifies Catalyst 9115AX as the migration family. Available inventory does not extend those milestones.
