Mixing these boards with parts from another set will result in an NVRAM mismatch error. Confirm that you have the corresponding serialized Display Panel Board before beginning installation.

Identified by Lexmark part number 41X4478, this controller board is intended for the MS431dw configuration. Match the model and part number before ordering.
Preserve the matched configuration.
Keep the controller and its associated Display Panel Board together throughout servicing. Their serialized relationship is essential to the installation requirements for this offering.
