The other two slots on the system board (MEZZ1_FAB_C and MEZZ2_FAB_B) are occupied by the mezzanine interface card which provides connectivity between the PCIe expansion-card riser and the system board. For PowerEdge M610x in bay n: • Mezzanine card B (in the expansion bay) connects to I/O module B1, port n+8 and I/O module B2, port n+8. • Mezzanine card C (in the expansion bay) connects to I/O module C1, port n+8 and I/O module C2, port n+8.
