Mezzanine Card Installation Guidelines

Full-Height Blades
Full-height blades support up to four mezzanine cards.
NOTE:
Even though 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.
• Slot 1 and slot 3 support Fabric C. They must match the fabric type of the
I/O modules installed in I/O module bays C1 and C2.
• Slot 2 and slot 4 support Fabric B. They must match the fabric type of I/O
module installed in I/O module bays B1 and B2.
CAUTION:
For M610x only, a bifurcated mezzanine card (that uses two
independent PCIe x4 controllers) cannot be installed in MEZZ1_FAB_C1 slot
unless either a bifurcated mezzanine card is also installed in MEZZ2_FAB_B1 slot
or no mezzanine card is installed in MEZZ2_FAB_B1. BIOS will halt during POST if
a non-supported mezzanine card configuration is detected.
NOTE:
Quad-port Ethernet mezzanine cards are bifurcated.
NOTE:
The four mezzanine card slots do not need to be fully populated.
If a blade does require support by a particular fabric and only two external I/O
port connections are needed, only one mezzanine card is required. For
example, a Fibre Channel I/O module in I/O bay C1 or C2 only requires one
Fibre Channel mezzanine card in slot 1 or slot 3 in the blade.
If a blade does not require support from a particular fabric, a mezzanine card
is not required in either of the corresponding mezzanine card slots.
Types of Cards Supported
• The M610x supports two small-form factor (SFF) mezzanine cards. x8
PCIe Gen 1 and x8 PCIe Gen 2 cards are supported.
• M910 supports SFF mezzanine cards in all four slots. x8 PCIe Gen 1 and
x8 PCIe Gen 2 cards are supported.
• The M710 supports SFF and LFF mezzanine cards in all four slots. x8
PCIe Gen 1 and x4 PCIe Gen 2 cards are supported.
• The M905 and M805 blades support LFF x8 PCIe Gen 1 mezzanine cards
in all four slots.
