Checking HC900 Model Numbers for Compatibility
ATTENTION
Be sure to check your model numbers for compatibility before installation. For a 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, 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.
