applicable to the new ControlEdge HC900 system. Modems are not qualified with the new ControlEdge
HC900 system.
Checking ControlEdge HC900 Model Numbers for Compatibility
ATTENTION
Be sure to check your model numbers for compatibility before installation. For a ControlEdge HC900
system to be fully compatible, all components must have matching model numbers.
Each component’s model number format is XXXXXXX–XXYY-ZZ. For example,
ControlEdge HC900 CPU is 900C71R-0000-40. For redundant CPU systems,
component model numbers ZZ numbers must match. For non-redundant CPU
systems, component model numbers YY numbers must match. See examples
below.
