Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity

definitions.

• Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations.

You and Cisco will commit all necessary resources around the clock to resolve the situation.

• Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of

your business operation are negatively affected by inadequate performance of Cisco products. You

and Cisco will commit full-time resources during normal business hours to resolve the situation.

• Severity 3 (S3)—Operational performance of your network is impaired, but most business

operations remain functional. You and Cisco will commit resources during normal business hours

to restore service to satisfactory levels.

• Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation,

or configuration. There is little or no effect on your business operations.

Cisco 4400 Series Wireless LAN Controllers - Installation and Configuration Guide

78-17157-01

Installation and Configuration

These controllers offer the highest level of performance and scalability for large-scale enterprise WLAN

deployments. In addition, these controllers deliver WLAN services over an existing ethernet or IP

infrastructure, protecting existing network investments while providing best-in-class wireless services.

As a core component of the award-winning Cisco Wireless LAN Solution, these controllers deliver

wireless security, intrusion detection, RF management, Quality of Service (QoS) and mobility across an

entire enterprise. It works in conjunction with other controllers, Cisco WCS, and access points to provide

network managers with a robust Wireless LAN (WLAN) solution that enables business-critical wireless

applications. From voice and data services to location tracking, the controllers provide the control,

scalability, and reliability that IT managers need to build secure enterprise-scale wireless networks.

This document is written assuming that you have already determined the 802.11 topology. 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 a controller.

The controller is 17.5 in. wide x 15.75 in. deep x 1.75 in. high (443 x 400 x 44.5 mm). The chassis can

be rack or shelf mounted.

The controller comes in 2 variants—4402 and 4404.

The 4404 controller has four front-panel slots for 1000BASE-SX, 1000BASE-LX, or 1000BASE-T SFP

modules, as described in the 1000BASE-SX, 1000BASE-LX, and 1000BASE-T SFP module Quick Start

Guide.

The 4402 Cisco Wireless LAN Controller is similar, except that it has two front-panel slots for

1000BASE-SX, 1000BASE-LX, or 1000BASE-T SFP modules instead of four. The 1000BASE-SX SFP

module provides 1000 Mbps wired connections through 850nM (SX) fiber-optic links using LC physical

connectors. The 1000BASE-LX SFP module provides 1000 Mbps wired connections through 1300nM

(LX/LH) fiber-optic links using LC physical connectors. The 1000BASE-T SFP module provides

1000 Mbps wired connections through CAT-5 or higher cables using RJ-45 physical connectors.

4402 Series Controller

There are three types 4402 series controllers:

• AIR-WLC4402-12-K9—This 4402-12 controller uses two redundant GigE connections to bypass

single network failures. That is, at any given time one of the Cisco 4400 Series Wireless LAN

Controller GigE connections is active and the other is passive. In case of a network failure, the active

connection becomes passive, and the passive connection becomes active. The 4402 controller has

one back-panel slot for future expansion modules and communicates with up to 12 access points

• AIR-WLC4402-25-K9—This 4402-25 controller uses two redundant GigE connections to bypass

single network failures, and communicates with up to 25 access points. It has one back-panel slot

for future expansion modules.

• AIR-WLC4402-50-K9—This 4402-50 controller uses two redundant GigE connections to bypass

single network failures, and communicates with up to 50 access points. It has one back-panel slot

for future expansion modules.

4404 Series Controller

There is only one type of 4404 series controller

• AIR-WLC4404-100-K9—This 4404-100 controller uses four redundant GigE connections to

bypass one or two single network failures, and communicates with up to 100 access points. It has

two back-panel slots for future expansion modules.

For information on installing the network adapter modules, refer to the 1000BASE-SX, 1000BASE-LX,
