I/O Module Mezzanine Cards
The blades support a variety of optional mezzanine cards. If installed, the
mezzanine card(s) must be used in conjunction with a matching appropriate
I/O module(s). (For more information on I/O modules, see "Guidelines for
Installing I/O Modules" on page 42.)
Mezzanine Card Installation Guidelines
PowerEdge M905 and M805
The full-height PowerEdge M905 and M805 blades support up to four
mezzanine cards.
• Slot 1 and slot 3 support Fabric C. If a card is installed in both slots, both
cards must be identical. They must also 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. If a card is installed in both slots, both
cards must be identical. They must also match the fabric type of I/O
module installed in I/O module bays B1 and B2.
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.
PowerEdge M600 and M605
The half-height PowerEdge M600 and M605 blades support two mezzanine
cards:
• Mezzanine card slot C supports Fabric C. This card must match the fabric
type of I/O modules installed in I/O module bays C1 and C2.
• Mezzanine card slot B supports Fabric B. This card must match the fabric
type of I/O modules installed in I/O module bays B1 and B2.
