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.

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

Using the Startup Wizard
Step 3 If this is the first time the controller has been powered up, or if you enter ‘Recover-Config’ in the User:
prompt, the bootup script runs the Startup Wizard, which prompts you for basic configuration input.
If this is the atleast the second time you have powered up the controller, the bootup script prompts you
for a login and password. Enter the login and password as described in “Logging In,” or enter
Recover-Config to reset the controller configuration to factory defaults.
In either of the two cases explained above, the controller has passed the POST test.
Using the Startup Wizard
The first time you power up the controller with a new factory-default Operating System configuration,
use the Startup Wizard to do the following:
Note Use the information you collected in “Collecting Required Tools and Information” for this step.
1. Enter the system (controller) name, up to 32 printable ASCII characters.
2. Enter the Administrative user name and password, each up to 24 printable ASCII characters. The
