Allowable Data Interface Combinations

Data interfaces are installed or removed from the rear of the CDM-710G chassis into Slot 1 and
Slot 2 of the CDM-710G. The allowable combination of data interfaces and the data interfaces
that are supported for redundancy are found in the table below. In all cases, only one data
interface is active at a time.
