Configuring Network Settings For The I/O Module; Expansion Bus; Pcie Expansion Slot Mapping; Pcie Slot Mapping From Compute Sleds - Dell PowerEdge FX2 Owner's Manual

Manual at Dell.com/poweredgemanuals. The PCIe mezzanine cards are mapped to the PCIe
expansion slots on the enclosure. For more information, see
NOTE: Only PCIe mezzanine cards can be installed in the compute sleds. Non-PCIe mezzanine
cards such as Ethernet, Fibre Channel, or InfiniBand mezzanine cards are not supported. If a
non-PCIe mezzanine card is installed in the compute sled, the amber light blinks on the
compute sled to indicate a mismatch, and the sled does not power on.

Configuring network settings for the I/O module

You can specify the network settings for the interface used to manage the I/O module.
Before configuring the network settings for the I/O module, make sure the I/O module is turned on.
To configure the network setting, you must have administrator privileges for the LOM network to
configure the I/O module in Group A.
You can configure the network settings by using the following:
• CMC Web interface
• RACADM
For more information on configuring the network settings, see the Dell PowerEdge FX2/FX2s CMC User's
Guide at Dell.com/esmmanuals.

Expansion bus

Expansion bus refers to the PCIe connections between the compute sleds and the PowerEdge FX2s
enclosure. The expansion bus supports PCIe mezzanine cards installed in the compute sleds. PowerEdge
FX2s has two PCIe switches integrated on the PCIe switch board to connect the compute sleds to the
eight low-profile PCIe expansion slots on the enclosure. Each half-width and quarter-width compute
sled supports one PCIe mezzanine card. Each full-width compute sled supports two PCIe mezzanine
cards.
NOTE: PowerEdge FX2 does not support expansion bus.

PCIe expansion slot mapping

Your system includes two PCIe switches that are integrated on the PCIe switch board. The PCIe
mezzanine card(s) in each compute sled is mapped to the PCIe switches, which are further mapped to
the PCIe slots on the PCIe switch board.
NOTE: The PCIe expansion slot mapping is pre-configured.
