Cisco Systems 8500 User Manual

The SFP+ module supported by the Cisco 8500 Series Wireless Controller is the Cisco SFP-10G-SR.

Cisco SFP-10G-SR: The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber 
Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000 MHz*km MMF(OM3), 
up to 300m link lengths are possible.

Depending on the distribution system physical port to be assigned, use only standard compliant 
fiber-optic cables to connect the network equipment to the controller

Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC 
connectors are not supported. All cables and cable assemblies used must be compliant with the standards 
specified in the standards section.

The service port is controlled by the service-port interface and is reserved for out-of-band management 
of the controller and system recovery and maintenance in the event of a network failure. The service-port 
interface enables the controller to be managed on an interface different from the one used for your 
network traffic. Use of the service port is optional.

You can perform out-of-band controller management from a PC running a terminal emulation program 
or a PC running Cisco WCS, a network management tool that enables you to configure and monitor a 
network of controllers, or the controller GUI. However, you must first connect the PC to the controller’s 
service port in one of two ways:

Use an Ethernet cross-over cable to connect the PC directly to the controller’s service port.

For a remote connection (using Telnet or SSH) through a dedicated management network, use a 
Category 5, Category 5e, Category 6, or Category 7 Ethernet cable to connect the management 
network to the controller’s service port and the appropriate cable to connect the PC to the 
management network.

After you have configured the controller, use Category-5, Category-5e, Category-6, or Category-7 
Ethernet cables to connect Cisco lightweight access points to the network.

As soon as the controller is operational, it starts to scan for access points. When it detects an access point, 
it records the access-point MAC address in its database. The controller radio resource management 
(RRM) feature then automatically configures the access point to start sending and allowing clients to 
associate.

You have prepared the controller for basic operation. Refer to the Cisco Wireless LAN Controller 
Configuration Guide, Release 7.0, for information on configuring the controller to meet the specific 
needs of your wireless network.
