Appendix B: Installing MTRX Expansion Cards 39
7 Carefully move the motherboard back into its original position by doing the following:
• Make sure the ports on the MADI module are aligned with the open Optical I/O slot of the back panel.
Guide the ports through the slot while moving the motherboard back into position, if necessary.
• Make sure the four motherboard mounting holes align with their threaded receivers on the bottom of
the unit.
• The raised tab on the Main Board multi-pin connector fits underneath the top of its receiver port. With
the connector properly aligned, pinch the two sides together to ensure a proper connection and correct
positioning of the motherboard.
8 Secure the motherboard back to the bottom panel of the unit using the same five screws you removed in
step 3, and secure the same fourteen screws on the back panel that you removed in step 2.
9 From the back of the unit, secure the MADI module to the back panel using the two faceplate screws you
removed earlier (two extras are included with the MADI module).
