Cisco Catalyst 4500 1400W AC Power Supply PWR-C45-1400AC Manual De Usuario

Cisco IOS Release 12.2(20)EU2 is an Early Deployment (ED) release based on Cisco IOS Release
12.2(20)EWA.

This document supersedes and replaces Release Notes for the Cisco uMG9850 QAM Module, Cisco IOS
Release 12.2(20)EU1.

Although Cisco IOS Release 12.2(20)EU1 has been removed from CCO, no catastrophic or deferring
defect exists. You do not need to upgrade your images. A legacy feature has been removed, and images
with that feature are no longer available on CCO. You may continue to operate with existing copies of
Cisco IOS Release 12.2(20)EU1 in your network.

Cisco IOS Release 12.2(20)EU2 is compatible with Cisco IOS Release 12.2(20)EWA. Cisco IOS
Release 12.2(20)EU2 is designed, however, to support the functionality of the Cisco uMG9850 in VoD
and digital broadcast applications. Not all features applicable to traditional switching apply to the Cisco
uMG9850. For configuration instructions and the command reference for the Cisco uMG9850, refer to
Configuring the Cisco uMG9850 QAM Module in

The Cisco uMG9850, designed for the Cisco Catalyst 4500 series switches, provides video-on-demand
(VoD) and digital broadcast services for a hybrid fiber-coaxial (HFC) cable network. It accepts Moving
Pictures Expert Group-2 (MPEG-2) digital video from an IP network, and outputs the video as a
quadrature amplitude modulated (QAM) RF stream that can be received by digital set-top boxes (STBs)
over the cable network.
