Poweredge Fx2/Fx2S Mapping Configurations; Lan On Motherboard Network; Supported I/O Modules - Dell PowerEdge FX2 Owner's Manual

PowerEdge FX2/FX2s mapping
configurations
This section provides the following information on the connectivity of the compute sleds to the I/O
module(s), PCIe slots, and Chassis Management Controller (CMC) of the enclosure:
• LAN On Motherboard network and compute sled to I/O module port mapping configurations
• Expansion Bus and compute sled to PCIe expansion slot mapping configurations
• Internal management network
NOTE: The I/O module port mapping and PCIe slot mapping from compute sleds are pre-
configured.

LAN On Motherboard network

LAN On Motherboard (LOM) network refers to the Ethernet connectivity provided to the compute sleds
by the I/O modules installed at the back of the PowerEdge FX2/FX2s enclosure.
LOM network provides four connections per half-width compute sled, two connections per quarter-
width compute sled, and eight connections per full-width compute sled for a maximum of 16 lanes. The
maximum external connections possible are 16 RJ-45 Ethernet ports.

Supported I/O modules

The enclosure supports up to two switches or pass-through modules. The maximum width for an
Ethernet pass-through module is eight lanes.
The following I/O modules are supported on the enclosure:
• Dell PowerEdge FN 410S I/O Module
• Dell PowerEdge FN 410T I/O Module
• Dell PowerEdge FN2210S I/O Module
• PowerEdge FX2 and FX2s 1 Gb x8 RJ45 pass-through module
• PowerEdge FX2 and FX2s 10 Gb x8 SFP+ pass-through module
– The 10 Gb pass-through module supports both 10 GbE SFP+ and 1 GbE SFP optical module. The
10 Gb pass-through module supports 1 Gb and 10 Gb connections.
– Use SFP+ to configure 10 Gb pass-through module and SFP or 1 Gb TOR switch to configure 1 Gb
pass-through module.
– Using a dual-rate optical module for a 1 GbE connection on the 10 Gb pass-through module
results in an invalid link.
– Use a dual-rate SFP+ optical module to configure a 10 GbE connection.
