AIRAP1852I-FK910C Cisco Aironet 1850i 4x4 MIMO AP 10-pack

AIR-AP1852I-FK910C exact order identity

AIR-AP1852I-FK910C is a 1852i indoor access point with integrated omnidirectional antennas in the Cisco Aironet 1850 Series. This exact SKU combines regulatory-domain token F 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.

F regulatory-domain evidence

Cisco lists this profile as 2.4 GHz channels 1-13; 5 GHz blocks at 5.250-5.350 and 5.725-5.825 GHz. The F profile is split between a compact mid-lower block and a high block. It does not match the common 5.180 GHz starting point, so imported controller templates require deliberate review. Validate both separated channel groups on the target controller and confirm that the RF survey used the same boundaries. Record any disabled channel and its local regulatory reason.

Procurement inference: the two separated 5 GHz ranges call for a survey that distinguishes the mid-lower group from the high group. Confirm that expected clients, neighboring radios and controller policy can use the approved choices at the destination. When replacing a unit from a different domain, do not preserve old channel assignments blindly; generate a new assignment and compare measured interference in both F-profile groups.

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.

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.

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. Relate the survey result to the 1852's 4x4:4 single-user and 4x4:3 multiuser 5 GHz design rather than treating the published 1.7 Gbps PHY rate as measured site throughput.

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.

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.

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 inspection should distinguish the internal-antenna 1852i from the external-antenna 1852e and should verify all carton quantities before labels are separated.

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.

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.
