Cables to Go Vipersat Network Router User Guide for Upgrade Procedures and Compatibility

General

Since there is no way to guarantee all Remote sites will be online during the initial upgrade to v1.5.3, Vipersat is providing this migration procedure and util- ity to facilitate picking up new or offline units. This migration tool includes non-saved control parameters at Hub units only that allow the operator to select compatibility mode with v1.5.2 (or earlier) firmware. When the operator initiates this backwards compatibility migration control, communications with all Remote units at the newly upgraded version 1.5.3 will be lost during that time. However, when the migration parameter is set in the TDM outbound and the appropriate Burst Controller(s), communications with v1.5.2 (or earlier) straggler/offline Remotes will be restored. At this point they can be upgraded to v1.5.3, restoring total network wide communications.

This will represent a network outage to all Remotes connected to the TDM outbound. In networks with a DVB outbound, only those Remotes associated (grouped) with the Burst Controller set to v1.5.2 compatibility will lose commu- nications.

Great care should be exercised in following these steps as outlined in this docu- ment. It is important to remember that network communications will not be effected until the units are rebooted to v1.5.3 router code. The last section of this document addresses recovering stragglers/offline remotes.
