Ethernet IO Modules
The MX7000 supports the following Ethernet I/O Modules (IOMs):
● Managed Ethernet switches:
○ MX9116n Fabric Switching Engine
○ MX5108n Ethernet Switch
● Unmanaged devices:
○ MX7116n Fabric Expander Module
○ PowerEdge MX 25 Gb Ethernet Pass-Through Module
○ PowerEdge MX 10GBASE-T Ethernet Pass-Through Module
Ethernet IOMs are supported in Fabrics A and B. For details about the supported IOM slots, see Supported slot configurations
for IOMs.
The Ethernet switches operate in two modes:
● Full Switch mode (default)
● SmartFabric Services mode or Fabric mode
By default, an Ethernet switch operates in Full Switch mode.
In Full Switch mode, the switch operates as a full L2/L3 switch with all functionality that is supported by the OS10 and the
underlying hardware. The switch configuration is done through the CLI. For information about configuring a switch using the
CLI, see the OS10 Enterprise Edition User Guide.
NOTE:
While replacing IOMs in full switch mode, remove the IOM before removing the ISL cables to prevent possible
split-brain situations.
You can use OME–Modular to perform the following tasks:
● Configure hostname, SNMP, and NTP settings.
● Configure port breakout modes.
● Set ports up or down.
● Monitor health, logs, alerts, and events.
● Update and manage firmware.
● View the physical topology.
● Perform power control operations.
It is recommended that you use the full switch mode when you require a feature or network architecture that is unavailable with
SmartFabric Services.
For information about Fabric mode, see SmartFabric Services.
Managing Ethernet IOMs
The I/O Modules page displays the health and asset information of the IOMs. If you have the fabric manager role with device
configuration and power control privileges, you can perform the following tasks on the I/O Module page:
● Power Cycle—Turn on, turn off, or perform a system reseat on the IOM
● Update firmware, if applicable
● Blink LED—Turn on or turn off the IOM Identification LED
● Refresh Inventory
You must have the device configuration privileges to set up network IOMs and perform configuration tasks on them.
NOTE:
The perpetual license comes by default with the factory shipped IOMs. If you perform ONIE install on the IOM, the
perpetual license is removed and replaced with the evaluation trail license. It is recommended to contact DELL support for
the perpetual license installation after the ONIE install is complete.
