I/O Module And Pcie Mezzanine Card Configuration Guidelines - Dell PowerEdge FX2 Owner's Manual

In the three-bay chassis, a full-width compute sled is mapped to four ports on each I/O module. A half-
width compute sled with quad port NDC is mapped to two ports on each I/O module.
NOTE: A half-width compute sled with dual-port NDC is mapped to a single port on each I/O
module.
NOTE: In the three-bay PowerEdge FX2s configuration that supports storage sled(s) mapped to a
full-width compute sled, only the compute sled is mapped to the I/O module ports. If storage sleds
are installed, the corresponding ports on the I/O modules mapped to these slots are not active.

The following table lists the compute sleds and the ports to which they are mapped.

I/O module and PCIe mezzanine card configuration
guidelines
• LOM network supports two Ethernet pass-through or switch modules.
• To enable switch configuration before imaging the compute sleds, you must allow the I/O module(s)
to power up before turning on the compute sleds.
• Each half-width and quarter-width compute sled installed in the PowerEdge FX2s enclosure supports
one PCIe mezzanine card. Each full-width compute sled supports two PCIe mezzanine cards. To
locate the PCIe expansion bus slots in the compute sleds, see the relevant compute sled Owner's
