Before You Start
By following the instructions in the Dell PowerEdge FN I/O Module Getting Started Guide that is shipped with the product, you
install the FN I/O Module in a Dell PowerEdge FX2 server chassis.
The Aggregator installs with zero-touch configuration. After you power it on, an Aggregator boots up with default settings and
auto-configures with software features enabled. This chapter describes the default settings and software features that are
automatically configured at startup. Use the tasks described in the other chapters to reconfigure the Aggregator for customized
network operation.

Operational Modes
The FN I/O Module supports four operational modes. Select the operational mode that meets your deployment needs. To enable
a new operational mode, reload the switch.
● Standalone mode — stack-unit unit iom-mode standalone. This is the default mode for IOA. It is fully automated
zero-touch mode that allows you to configure VLAN memberships. (Manageable through CMC also)
● Programmable MUX mode (PMUX) — stack-unit unit iom-mode programmable-mux. Select this mode to
configure PMUX mode CLI commands.
● Stacking mode — stack-unit unit iom-mode stacking. Select this mode to stack up to six IOA stack units as
a single logical switch. The stack units can be in the same or on different chassis. This is a low-touch mode where all
configuration except VLAN membership is automated. To enable VLAN, you must configure it. In this operational mode, ports
9 and 10 are dedicated to stacking.
● Virtual Link Trunking mode (VLT) — stack-unit unit iom-mode vlt. Select this mode to multi-home server
interfaces to different IOA modules. This is a low-touch mode where all configuration except VLAN membership is
automated. To enable VLAN, you must configure it. In this mode, ports 9 is configured as VLT interconnect.
● Full Switch mode — stack-unit unit iom-mode full-switch. The full switch mode provides Layer 2 / Layer 3
functionalities on the Dell FX2 chassis. All the commands and configurations supported on the MXL is available in full-switch
mode.
For more information, see the FN IOM Configuration Guide.
