CISCO AIR-CT2504-50-K9 2504 Wireless Controller 50-AP License

50-AP Cisco 2504 Controller Order

AIR-CT2504-50-K9 is the exact Cisco 2504 wireless-controller PID for up to 50 Cisco access points. The number embedded in the PID identifies base AP-license capacity; it does not state client count, AP compatibility, software release or high-availability behavior.

Capacity selection decision

Use the 50-AP order only after mapping controller CPU, client load, uplink design, software support and failure domain for the larger estate. Fifty licensed APs does not provide controller stateful switchover or eliminate the need for a migration plan.

Software and AP compatibility gate

Inventory every AP PID and regulatory domain, then verify support in the intended AireOS release before purchase. Save controller configuration, license summary, AP join state, mobility design, WLAN/security settings and management dependencies.

Commissioning evidence

Validate a full inventory reconciliation, backup and restore, uplink redundancy, representative roaming and peak client load. Preserve an outage plan because the 2504 HA PID does not provide AP/client stateful switchover.

Lifecycle and migration

Cisco has ended sale for the 2504 controller. Verify the exact support status and map AP compatibility, WLAN policy, licensing, controller capacity and redundancy to the selected Catalyst 9800 migration design rather than assuming configuration parity.
