AIR-AP4800-B1-K9 - Cisco Aironet 4800 Access Point

AIR-AP4800-B1-K9 Order Identity

AIR-AP4800-B1-K9 is a Cisco Aironet 4800 Series, controller-based 802.11ac Wave 2 access point order. This exact SKU is a 4800 internal-antenna access point, carries regulatory-domain token B1, and uses a fixed-domain single-unit order.

Antenna and quantity boundary

Integrated multiradio antenna system; no external Wi-Fi antenna is selected as part of this SKU. Confirm mounting orientation, ceiling structure, Hyperlocation requirements and RF survey assumptions because the antenna system is integral to the platform.

This K9 order form represents one access point; antennas, mounting choices, power source and controller dependencies remain separate unless the authorized bill of materials states otherwise.

This is a non-C fixed-domain order form. Receiving must match the exact domain-bearing SKU and must not substitute a configurable or different-domain line without approval.

Regulatory-domain control

The order carries regulatory-domain token B1. Treat that token as an identifier, not a country name. Complete order-country consistency and local spectrum validation against Cisco's current compliance resources before shipment or activation.

Cisco uses the variable regulatory-domain position in its ordering structure. Deployment eligibility must be checked for the destination country; this page does not infer a country mapping from token B1.

Power budget

Confirm the switch port's negotiated PoE mode, available power, cable length and LLDP behavior. Keep the measured power result with commissioning evidence. Measure the power state after both radios and production features are active, not only while the unit is idle. Record switch model, port, power class, negotiated result and any feature reduction shown by the controller. If an injector is proposed, verify its Cisco support and place it in the maintained bill of materials.

Multigigabit uplink

The 3800 Series supports multigigabit Ethernet. Verify the switch port, cabling category, negotiated rate and error counters instead of assuming a 2.5 or 5 Gbps link. Commissioning should preserve the negotiated Ethernet rate, cable-test result, packet errors and switch configuration. Where the access switch is limited to 1 Gbps, state that design choice explicitly instead of presenting multigigabit capability as achieved throughput. Recheck negotiation after patch-cord or switch changes.

Regulatory approval

Use Cisco's country compliance information for the deployment address and retain the result. The domain letter must not be translated into a country from memory. Keep the Cisco lookup date, destination country, approved domain and reviewer with the asset record. If the deployment country changes, stop and repeat the approval rather than assuming that a previously purchased AP can move across borders. Controller settings and antenna choices must remain consistent with that evidence.

Cable qualification

Test the permanent link and preserve the cable result, patch-cord identity and switch port. A successful low-speed link does not prove multigigabit readiness. Store the certification result for the permanent link and both patch leads, including the test standard and date. Investigate pair faults, excessive length and negotiation fallback before AP commissioning. Link the cable record to the switch port and AP serial so later throughput problems can be separated from radio behavior.

Migration dependency

Inventory controller, licensing, switch power, cabling and mounting dependencies that must change when the 3802 is replaced by a newer platform. Map the existing AP to its controller, licenses, authentication services, switch port, power budget, cable, bracket and monitoring objects. The successor plan should state which dependencies can be reused and which require change. This prevents a nominal AP replacement from failing because the surrounding platform was never inventoried.

Change control

Define the staging date, installation window, rollback owner and validation threshold before the AP is joined to a production controller. The change record should list staging evidence, production window, responsible installer, rollback decision and success criteria. Preserve the previous controller or AP state needed for recovery. After the window, close temporary credentials and compare monitoring, authentication and RF results with the approved baseline before declaring completion.

Lifecycle and migration evidence

Cisco's support site lists an end-of-life announcement for the Cisco Aironet 4800 Series. Confirm current support dates, controller compatibility and the approved replacement path before treating available stock as suitable for a new deployment.
