AIR-CT2504-15-K9 is the exact Cisco 2504 wireless-controller PID for up to 15 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.
Use the 15-AP order for a small controller domain whose production, spare and growth count remains within fifteen. Preserve at least one capacity position for controlled replacement or staging instead of licensing exactly to the current live count.
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.
Join a representative AP, validate WLANs and wired reachability, then reconcile all fifteen license positions against the controller license summary. Record the trigger for moving to a larger capacity or replacement platform.
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.
