Port Auto-Disablement In Quad-Port Network Daughter Card (Poweredge M710Hd Only) - Dell PowerEdge M620 Owner's Manual

NOTE:
Modules designed specifically for Fabric B or Fabric C cannot be installed in
slots A1 or A2, as indicated by the color-coded labeling on the faceplate of each
module.
Fabric B
Fabric B is a 1 to 40 Gb/sec redundant fabric, supporting I/O module slots B1
and B2. Fabric B currently supports 1 Gb or10 Gb Ethernet, DDR/QDR
Infiniband, and 4 Gbps or 8 Gbps Fibre Channel modules. Additional fabric
types may be supported in the future.
NOTE:
If the midplane version in the enclosure is 1.1 or later, Fabric B supports up
to 16 Gbps Fibre Channel, Infiniband FDR (14 Gbps standard), and KR (10 Gbps
standard). To identify the midplane version, see "Identifying Midplane Version" on
page 38.
To communicate with an I/O module in the Fabric B slots, a blade must have
a matching mezzanine card installed in a Fabric B mezzanine card location.
Modules designed for Fabric A may also be installed in the Fabric B slots.
Fabric C
Fabric C is a 1 to 40 Gb/sec redundant fabric, supporting I/O module slots C1
and C2. Fabric C currently supports 1 Gb or10 Gb Ethernet, DDR/QDR
Infiniband, and 4 Gbps or 8 Gbps Fibre Channel modules. Additional fabric
types may be supported in the future.
NOTE:
If the midplane version in the enclosure is 1.1 or later, Fabric C supports up
to 16 Gbps Fibre Channel, Infiniband FDR (14 Gbps standard), and KR (10 Gbps
standard). To identify the midplane version, see "Identifying Midplane Version" on
page 38.
To communicate with an I/O module in the Fabric C slots, a blade must have
a matching mezzanine card installed in a Fabric C mezzanine card location.
Modules designed for Fabric A may also be installed in the Fabric C slots.
