AIR-AP3802E-B-K9 exact order identity

AIR-AP3802E-B-K9 is a controller-based Cisco Aironet 3800 Series 802.11ac Wave 2 access-point order. The PID selects the 3802E access point for external antennas, single-unit fixed-domain K9 order and regulatory token B.

Antenna architecture

The 3802E requires separately selected compatible external antennas; connector fit alone is not an approved RF design. Record antenna PID, connector use, gain, pattern, cable loss, mounting, grounding and country approval.

Quantity and configuration boundary

This K9 line is a single access-point order. Antenna, mounting, power and controller dependencies remain separate bill-of-material decisions.

B regulatory evidence

The domain token is not a country name. Match the B-domain carton label to the purchase line before serial assignment, then archive the dated compliance lookup.

Build the B-domain record around quotation-to-asset traceability. Preserve the authorized line, received label, chassis serial, assigned site and reviewer as one chain. If the controller later moves to another country configuration, open a new approval event rather than overwriting the original evidence; the history should explain both the purchased identity and every deployment decision.

Controller, PoE and uplink boundary

Validate the exact controller release and CAPWAP join before deployment. Preserve negotiated PoE, multigigabit Ethernet rate, cable certification and error counters; family capability does not prove the installed switch and cable path achieve that rate.

Lifecycle and migration decision

Cisco lists 2022-10-31 as end of sale and 2027-10-31 as last support for the Aironet 3800 Series, with Catalyst 9130AX as the replacement direction. Available inventory does not extend those dates.

Deployment evidence worksheet

Controller join evidence

Stage the access point on the controller release intended for production. Retain the controller model, software version, discovery path, authorization method and first successful CAPWAP join. Confirm that configuration download completes and that both radios reach an expected operational state. Remove any temporary staging authorization before handover. This evidence separates an orderable access point from a unit that has actually been proven compatible with the planned controller environment. For this 3802 order, retain controller discovery, image transfer and final CAPWAP join by serial.

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 negotiated PoE state after radios and production features are active, not only at idle boot.

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. Prove the permanent link, patch leads, multigigabit switch port, negotiated rate and error counters.

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. Tie the post-install RF result to the exact integrated or external antenna architecture.

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 bracket, enclosure, restraint, cable entry and every external-antenna component before site work.

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. A ten-unit order still requires ten serial, MAC, site and controller asset records.

Country approval retention

Save the Cisco compliance lookup result, lookup date, deployment country, approved regulatory token and reviewer. If the destination changes, stop and repeat the approval rather than moving the unit on the strength of an earlier purchase. Compare the controller country setting and available channels with the retained evidence. Regulatory eligibility is a deployment condition and cannot be inferred from connector fit, stock location or a similar-looking part number. Save the Cisco country lookup and controller country setting with the exact regulatory token.

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 3802 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 antenna letter, domain, quantity or configurable suffix requires a new procurement review.
