The 1000BASE-SX SFP modules provide 1000 Mbps wired connections to a network through 850nM

(SX) fiber-optic links using LC physical connectors. The 1000BASE-LX SFP modules provide

1000 Mbps wired connections to a network through 1300nM (LX/LH) fiber-optic links using LC

physical connectors.

• Ensure that the power cord can reach a 110 or 220 VAC grounded electrical outlet.

Installing the Chassis

This section describes how to install the controller chassis.

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

The controller is shipped with rack-mounting ears attached, and the desktop/shelf mounting rubber feet

in a separate bag. Mount the controller as follows:

• When you are mounting the controller on a desktop or shelf, adhere the rubber feet to the bottom of

the chassis, and place the chassis on any secure horizontal surface.

Note You can also remove the rack mounting ears from the controller, if desired.

• When you are mounting the controller in an EIA-standard rack, attach the ears to the equipment rack

using the factory-supplied screws.

Caution The controller weighs 15.2 pounds (6.95 kg). For safety, two or more people must work together to

perform the installation.

You have installed the controller chassis.

Install the SFP modules as described in Quick Start Guide: 1000BASE-SX, 1000BASE-LX, and

1000BASE-T SFP Modules for Cisco 4400 Series Wireless LAN Controllers.

If you have purchased an extra power supply module or Enhanced Security Modules refer to the Quick

Start Guide: Power Supplies for Cisco 4400 Series Wireless LAN Controllers.

Warning

This unit might have more than one power supply connection. All connections must be removed to

de-energize the unit.
