Cisco Cisco 5508 Wireless Controller Installationsanleitung

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 switch’s 
service port in one of two ways:

Use an Ethernet cross-over cable to connect the PC directly to the switch’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 switch’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 6.0, for information on configuring the controller to meet the specific 
needs of your wireless network.

The controller can be powered using one or two power supply units. When the controller is equipped 
with two power supply units, the power supplies are redundant. Either power supply continues to power 
the controller should the other power supply unit fail. Also, the power supplies are hot swappable; you 
do not need to remove power from the controller to replace a power supply.

Before you remove or install a power supply, you must switch off and unplug the power supply.

One power supply unit is installed in slot 1 at the factory. You can order a second power supply unit and 
install it in slot 2.

If only one power supply will be used, you must use the supplied blank faceplate to cover the empty 
power slot.
