Overview

In order to avoid damage to the modems and CRS-150 switch, it is important for the
user to follow this sequence of configuration:
First, connect cables between the (powered OFF) modems and switch as
outlined previously in Chapter 4. CABLES AND CONNECTIONS.
Second, configure the modems for 1:1 redundant operation, as outlined in this
chapter in Sect. 5.2.
Third, once the modems have been properly configured for 1:1 redundant
operations, the user should then set the DIP switches on the CRS-150 to the
correct modem selection, as outlined in this chapter in Sect. 5.3 CRS-150
