Safety Considerations

•Verify that the ambient temperature remains between 32 to 104° F (0 to 40° C), taking into account the elevated temperatures when installed in a rack or enclosed space.

•When multiple 2504 controllers are mounted in an equipment rack, be sure that the power source is sufficiently rated to safely run all the equipment in the rack (input: 100 to 240 VAC, 50–60 Hz, output: 80 W per controller).

•Verify the integrity of the electrical ground before installing the controller.

Introduction to the Controller

The 2504 controller works in conjunction with Cisco lightweight access points and the Cisco Wireless Control System (WCS) to provide system-wide wireless LAN functions. As a component of the Cisco Unified Wireless Network (CUWN), the 2504 controller provides real-time communication between wireless access points and other devices to deliver centralized security policies, guest access, Wireless Intrusion Prevention System (WIPS), context-aware (location), award-winning RF management, quality of services for mobility services such as voice and video, and OEAP support for the Teleworker solution.

The 2504 controllers supports up to 50 lightweight access points in increments of 5 access points with a minimum of 5 access points, making it a cost-effective solution for retail, enterprise branches, and small and medium-sized businesses. The 2504 controller comes with four 4 Gigabit Ethernet ports.
