AIR-CT2504-25-K9 Overview
A physical controller with 25 AP licenses
AIR-CT2504-25-K9 combines the Cisco 2504 controller hardware with a 25-access-point license capacity. It is different from the LIC-CT2504-25A or L-LIC-CT2504-25A capacity adders, which do not supply another controller. The 25-AP figure describes the starting managed-AP capacity of this order.
Connections and capacity are separate limits
The chassis provides four 1-Gigabit RJ-45 Ethernet ports and an RJ-45 console connection. Cisco documents two PoE ports for directly connected access points and platform throughput of up to 1 Gbps. Additional licensed capacity can take the platform to 75 APs; that ceiling is not the included capacity of this 25-AP order.
Use the installed AireOS release to check AP compatibility
Match each access-point model to the controller software before choosing this legacy controller as a replacement. An AP count alone does not establish that a newer AP generation can join. For an existing deployment, retain its controller configuration and verify the installed license inventory before changing the hardware.
Support ended; distinguish legacy replacement from a new deployment
Cisco ended sale on April 18, 2018 and lists April 30, 2023 as the last date of support. This is an ended-support platform, not a currently supported new-generation controller. When evaluating a replacement, compare supported APs, licensing and migration requirements rather than assuming an existing configuration transfers unchanged.
