This guide provides step-by-step instructions for upgrading a Cisco Digital 

Broadband Delivery System (DBDS) to System Release (SR) 2.5 or SR 3.5. Sites that 

use this guide to upgrade must currently support one of the following system 

releases: 
• 

SR 2.2 or SR 3.2 

• 

SR 2.4 or SR 3.4  

SR 2.5 and SR 3.5 provide support for the Remote Network Control Server (RNCS) 

component of a Cisco Digital Broadband Delivery System (DBDS). The RNCS is a 

needed component in a Regional Control System (RCS) that uses the DNCS to 

manage remote headends. 

Cisco introduces the Live Upgrade with the SR 2.5 and SR 3.5 UniPack. Through use 

of the Live Upgrade, engineers can upgrade an Enterprise 450 and Sun Fire V880 

server without having to shut down the system processes until activation of the new 

system software. 

The upgrade to SR 2.5 or SR 3.5 is to be completed from within a maintenance 

window that usually begins at midnight. Cisco engineers have determined that a 

typical site can be upgraded within one maintenance window. The maintenance 

window should begin when you stop system components in Chapter 2 

Staging, third-party applications, video-on-demand (VOD), anything-on-demand 

(xOD), and interactive services, such as impulse pay-per-view (IPPV), will not be 

available during the maintenance window. 

This guide provides Cisco field service engineers with instructions for upgrading an 

existing DBDS to SR 2.5 and SR 3.5.
