Cisco Systems 4100 User Manual

Installation and Configuration

This document is written assuming that you have already determined the 802.11 topology as described in the ApplianceMode sections in the Product Guide. Because the Radio Resource Management (RRM) feature automatically detects and configures the access points as they appear on the network, it is not necessary to have any access points on the network to install and configure controllers.

The controller is a slim 9 x 5.5 x 1.5 in. (22.9 x 14.0 x 3.8 cm) chassis that can be rack, desktop, or shelf mounted. As shown in the following figures, the controller is shipped with 19 in. (48.26 cm) EIA rack-mount ears and four rubber mounting feet.

The following figure shows the controller, which has two front-panel 1000BASE-SX connectors.

Note The 1000BASE-SXNetwork Adapters provides 100/1000 Mbps wired connections toa network through

850nM (SX) fiber-optic links using LC physical connectors.

The controller communicates indirectly with up to:

• 12 associated Cisco 1000 Series lightweight access points (Model 4112).

• 24 associated Cisco 1000 Series lightweight access points (Model 4124).

• 36 associated Cisco 1000 Series lightweight access points (Model 4136).

Collecting Required Tools and Information

This section lists the tools and the information that you need to have before installing the controller.

Cisco 4100 Series Wireless LAN Controller Hardware

• Controller (ships with factory-supplied power cord and mounting hardware).

• Network, Management network, and access point cables, as required.

CLI Console

• VT-100 terminal emulator on CLI console laptop or palmtop.

• Null modem serial cable to connect CLI console and the controller DB-9 console port.

Local TFTP Server

This is required for downloading error-free software updates. (Contact Cisco Technical Assistance Center (TAC) for software updates.)

Collecting Required Tools and Information

Note The Cisco WCS uses an integral TFTP server. This means that third-party TFTP servers cannot run on

the same workstation as the Cisco WCS, because the Cisco WCS and the third-party TFTP servers use the same communication port.

Initial System Configuration Information

Obtain the following initial configuration parameters from the wireless LAN/network planner:

• System (Controller) name.

• Administrativeusernameandpassword.(DefaultAdministrativeusernameandpasswordareadmin

and admin, respectively.)

Note The Service-port interface and management interface MUST be on different subnets.

• Service-Port Interface IP address configuration protocol (none or DHCP). (Refer Figure 2 for the

service port location.)

• If service port configurationprotocol = none, Service Port (front-panel Service port) IP Address and

Service Port netmask.

• Management interface (DS Port, or Network Interface Port) IP address. (Refer to Figure 2 for the

distribution system port locations.)

• Management Interface netmask.

• Management Interface default router IP address.

• VLAN identifier,if the Management Interface is assigned to a VLAN, or ‘0’ for an untagged VLAN.

• Distribution System Physical Port number: 1 for either front panel GigE port

Installation and Configuration

• IP address of the default DHCP server that will supply IP addresses to clients, the controller

management interface, and optionally to the service port interface.

• LWAPP Transport Mode, LAYER2 or LAYER3 (refer to Layer 2 and Layer 3 Operation in the

Product Guide).

• VirtualGatewayIP Address: one fictitious, unassigned IP address (such as 1.1.1.1) to be used by all

Cisco WLAN Solution layer 3 security and mobility managers.

• Controller Mobility Group (RF Group) name, if required.

• 802.11 Network Name (SSID) for WLAN 1. This is the default SSID that the Cisco 1000 Series

lightweight access points broadcast when they associate with the controller.

• Whether or not to allow Static IP Addresses for clients.

* Yes = more convenient,but lower security (session can be hijacked), clients can supply their own IP Address, better for devices that cannot use DHCP. * No = less convenient, higher security, clients must use DHCP for an IP Address, works well for Windows XP devices.

• When you are configuring a RADIUS server, the server IP address, communication port, and Secret.

• Country Code for this installation. Refer to Configuring the Cisco Wireless LAN Controller and

Cisco WLAN Solution Supported Country Codes in the Product Guide.

• 802.11b network enabled or disabled?

Installation and Configuration

• 802.11a network enabled or disabled?

• 802.11g network enabled or disabled?

• Radio Resource Management (RRM) (Auto-RF) enabled or disabled?

Determining a Physical Location

The controller can be installed almost anywhere, butit is more secure and reliable if installed in a secure equipment room or wiring closet.

For maximum reliability, mount the controller using the following constraints:

• Be sure you can reach the controller and all cables.

• Be sure that water or excessive moisture cannot get into the controller.

• Ensure that airflow through the controller is not obstructed. Leave at least 4 inches clear on both

sides of the controller chassis.

• Verify that the ambient temperature remains between 0 to 40˚ C (32 to 104˚ F).

• Be sure that the controller is within one of the following distances of equipment connected to the

optional 1000BASE-SX port:

–

220 m (722 ft.) when using 160 MHz-km rated 62.5/125 m multimode fiber.

–

275 m (902 ft.) when using 200 MHz-km rated 62.5/125 m multimode fiber.

–

400 m (1312 ft.) when using 400 MHz-km rated 50/125 m multimode fiber.

–

500 m (1641 ft.) when using 500 MHz-km rated 50/125 m multimode fiber.
