Automatic MDI or MDIX detection
All 10/100 and Gbps Ethernet Copper ports on the devices support automatic Media Dependent
Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on
all 10/100 and Gigabit copper ports by default. For each port, you can disable auto MDI or MDIX,
designate the port as an MDI port, or designate the port as an MDIX port.
For more information about this feature and how configure it, refer to FastIron Ethernet Switch Security
Configuration Guide.
Connecting a network device to a fiber port
For direct attachment from the device to a Gbps NIC, switch, or router, using a fiber optic transceiver,
you will need fiber cabling with an LC connector.
To connect the device to another network device using a fiber port, you must do the following tasks:
• Install a fiber optic transceiver (XFP, SFP, or SFP+)
• Cable the fiber optic transceiver
The following sections describe these tasks.
Fiber Optic transceivers
The following table lists supported XFP transceivers (for stacking and non-stacking FCX models) and
supported SFP and SFP+ transceivers.
