Dual-Port Mezzanine Cards
Each mezzanine card has two port connections. For a full-height blade in bay n:
• Mezzanine card 1, connection 1 connects to I/O module C1, port n. Mezzanine card 1, connection 2
connects to I/O module C2, port n.
• Mezzanine card 2, connection 1 connects to I/O module B1, port n. Mezzanine card 2, connection 2
connects to I/O module B2 port n.
• Mezzanine card 3, connection 1 connects to I/O module C1, port n+8. Mezzanine card 3, connection
2 connects to I/O module C2 port n+8.
• Mezzanine card 4, connection 1 connects to I/O module B1, port n+8. Mezzanine card 4, connection
2 connects to I/O module B2 port n+8.
For example, in a full-height blade:
• Mezzanine card 3 connection 1 connects to I/O module C1, port 13.
• Mezzanine card 3 connection 2 connects to I/O module C2 port 13.
The following table shows the port number assignments for the eight possible full height blade locations.
NOTE: Even though PowerEdge M610x is a full blade system, only two mezzanine card slots
(MEZZ1_FAB_C1 and MEZZ2_FAB_B1) in the expansion bay are available for use. 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.
