Connecting Access Points; Installing A Power Supply Unit - Cisco 4404 - Wireless LAN Controller Quick Start Manual

Depending on the distribution system physical port to be assigned, use Ethernet Category 5 or higher
cables or SX/LX/LH compatible fiber-optic cables to connect the network equipment to the controller.
Connecting the Switch's Service Port (Optional)
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 a shielded, twisted-pair 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.

Connecting Access Points

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 3.4, for information on configuring the controller to meet the specific
needs of your wireless network.

Installing a Power Supply Unit

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 one or both power
supplies.
