This module presents the fail-over and redundancy capabilities of the SCE platform. It first defines
relevant terminology, as well as pertinent theoretical aspects of the redundancy and fail-over solution. It
then explains specific recovery procedures for both single and dual link topologies. It also explains
specific update procedures to be used in a cascaded SCE platform deployments. When fail over is
required in a deployment, a topology with two cascaded SCE platforms is used. This cascaded solution
provides both network link fail over, and fail over of the functionality of the SCE platform, including
updated subscriber state.
The information in this chapter applies to the SCE 2000 4xGBE and SCE 2000 4/8xFE platforms only.
