Note Direct connection of access points to Cisco 2500 Series Wireless Controllers are not currently
supported.
The 2504 controller offers robust coverage with 802.11 a/b/g and delivers unprecedented reliability
using 802.11n with Cisco Next-Generation Wireless Solutions and Cisco Enterprise Wireless Mesh.
To best use this guide, you should have already designed the wireless topology of your network and
have a working knowledge of how controllers function in a wireless LAN network.
Figure 1 shows a 2504 controller network topology and network connections, showing the medium
dependent interface (MDI) Ethernet cables required. The controller has an auto MDI feature, so you
can use straight-through or crossover cables.
