AIR-CT3504-K9 Overview

Separate the controller from its APs

The 3504 provides centralized wireless management rather than direct radio coverage. Cisco lists capacity up to 150 APs and 3,000 clients; those limits do not establish the licenses included with an individual unit. Confirm AP entitlement and the intended software release.

Review the remaining lifecycle

The manufacturer ended sales on January 31, 2021. Its published security-support milestone was January 30, 2025, and the last support date is January 31, 2027 subject to applicable entitlement. Do not treat the final support date as a guarantee of continuing security fixes or eligibility for a new contract.

Plan a controlled replacement

Record AP inventory and software compatibility, network uplinks, configuration recovery and the required migration window. Verify the supplied power adapter, mounting arrangement, unit condition and commercial support scope before ordering.
