9 PowerEdge FX2 – FN I/O Module – VLT Deployment Guide | Version 2.2
2.1 FN I/O Modules description
The PowerEdge FX2 is a chassis capable of housing compute, network and storage modules. The
network modules, referred to as one of three FN I/O Modules (FN IOMs), behave as traditional
network switches that are housed in the rear of the FX2 chassis. All three FN IOMs offer network
services for both the Ethernet and storage fabrics in a data center. While the FN410S is used in this
deployment guide, Dell EMC offers three options of FN IOMs providing plug-and-play Ethernet as well
as LAN/SAN convergence with iSCSI and FCoE. In addition to these features, the third model also
offers native Fibre Channel traffic using NPIV Proxy Gateway mode (NPG mode).

2.2 Networking Block FN Series Operational Modes
The FN IOM supports five operational modes: Standalone (SMUX), VLT, Stacking, Programmable
MUX (PMUX) and Full-switch. See Table 1 for detailed descriptions of each mode. To enable a new
operational mode the command stack-unit 0 iom-mode <IOM_Mode> is issued in configuration
mode. After enabling a new operational mode, the switch must be reloaded.
