AIRAP1852I-AK910C Cisco Aironet 1850i AP 10-pack with Mobility Express

AIR-AP1852I-AK910C exact order identity

AIR-AP1852I-AK910C is a 1852i indoor access point with integrated omnidirectional antennas in the Cisco Aironet 1850 Series. This exact SKU combines regulatory-domain token A 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.

A regulatory-domain evidence

Cisco lists this profile as 2.4 GHz channels 1-11; 5 GHz blocks at 5.180-5.320, 5.500-5.700 excluding 5.600-5.640, and 5.745-5.825 GHz. The A plan combines lower, middle and upper 5 GHz blocks, but the documented gap inside the middle block matters. The RF design and controller template must preserve that exclusion instead of treating the listed span as continuous. Export the controller channel list after provisioning and compare it with the approved A-domain record. Investigate any channel inside the excluded middle sub-block or any missing approval evidence before service activation.

Procurement inference: this profile is useful only when the destination approval and controller expose the documented lower, split-middle and upper choices. The middle exclusion should appear explicitly in the site worksheet, because a broad frequency-range label can conceal it. When migrating controllers, compare exported enabled-channel lists before and after the move; do not use unchanged SSID service as proof that the regulatory plan remained intact.

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

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. The platform has one PoE Gigabit interface and one Gigabit AUX interface used for link aggregation, so preserve both link states and the power condition under which AUX is available.

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.

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.

Change-window controls

Document staging evidence, production window, installer, rollback owner and measurable success criteria. Preserve the prior controller or AP state needed for recovery. After the change, close temporary credentials, compare authentication, monitoring and RF results with the approved baseline, and record the final decision. The work is not complete merely because the unit powers on or appears in a controller list. Rollback must account for controller image alignment, country configuration and any Mobility Express primary role, not only the physical swap.

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 the security behavior verified on the deployed controller release; do not turn a family data-sheet capability into an unconditional software claim.

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. Capacity acceptance should show actual client mix, airtime and retries under the available regulatory-domain channels, not only a maximum PHY figure.

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.

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.
