AIR-AP3802I-T-K9 Cisco Aironet 3800i Access Point Indoor environments

AIR-AP3802I-T-K9 exact order identity

AIR-AP3802I-T-K9 is a controller-based Cisco Aironet 3800 Series 802.11ac Wave 2 access-point order. The PID selects the 3802I access point with integrated antennas, single-unit fixed-domain K9 order and regulatory token T.

Antenna architecture

Cisco integrates the antennas into the 3802I enclosure, so no external antenna is selected by this PID. Retain enclosure orientation, bracket, mounting height and measured coverage against the approved RF survey.

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.

T regulatory evidence

The domain token is not a country name. Document the T-domain destination and controller country setting before installation, then keep the evidence through software upgrades.

Use software-upgrade governance for the T-domain record. Before an upgrade, preserve the controller country, enabled channels, AP serial and dated compliance lookup; after the change, capture the same fields for comparison. Investigate a changed radio state before production acceptance. This ties the domain decision to an observable configuration history instead of a one-time purchasing note.

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

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.

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.

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.

Roaming acceptance

Define the neighboring access points and client types used for roaming validation. Record handoff behavior, interruption observed, authentication result and controller events along the intended movement path. Compare the outcome with the site's design target rather than declaring success from static association. Where this unit replaces an older AP, test both entry and exit from its cell so a local improvement does not hide a boundary problem. Document roaming path, neighboring cells, client type and controller events at each cell boundary.

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.

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 restore controller assignment, country setting, switch port and prior RF service.
