AIR-AP3802E-Z-K9 - Cisco Aironet 3800E Indoor Access Point - External Antennas

AIR-AP3802E-Z-K9 exact order identity

AIR-AP3802E-Z-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 Z.

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.

Z regulatory evidence

The domain token is not a country name. Attach the Z-domain compliance lookup to the commissioning package and flag any later country-setting change for reapproval.

Build the Z-domain package as a commissioning baseline. Combine the exact PID, destination lookup, controller country, enabled-channel output, antenna or mounting evidence and representative client test under one review date. Later automatic radio changes may be operationally valid, but country-setting or hardware reassignment changes require explicit reapproval and a new baseline entry.

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

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.

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.

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.

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. Test stored spares against controller release, PoE, domain, antenna and mounting dependencies.

Authentication path test

Commission representative clients through association, authentication, address assignment, DNS and application reachability. Preserve the identity policy used, test client type, result and relevant controller logs. An access point that joins its controller has not yet demonstrated the user path. Repeat the test after any controller, certificate or authentication-service change and retain failures separately from RF or switch-port evidence. Commission association, authentication, addressing, DNS and application reachability on representative clients.

Monitoring handover

Assign owners for AP reachability, controller join failures, radio utilization, client health and switch-port errors. Confirm that the exact serial appears in inventory and monitoring, then test the alert path. Record dashboard object, notification route and escalation owner. Telemetry that is not tied to an owned asset does not provide a reliable service baseline and will not support later comparison after channel or software changes. Monitor serial, CAPWAP state, radio health, Ethernet errors, PoE and client experience under one owner.

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. Use measured airtime, retries and client performance instead of maximum family PHY rates.

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. Preserve the enabled-channel export after initial join and every controller migration.
