Automatic MDI or MDIX detection
Automatic MDI or MDIX detection
All 10/100 and 1000 Mbps 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 Mbps 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 to configure it, refer to the 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 need fiber cabling with an LC connector.
To connect the device to another network device using a fiber port, you must perform the following
tasks:
•
•
For instructions on installing fiber-optic transceivers, refer to
transceiver
For instructions on cabling a fiber-optic transceiver, refer to
86.
For instructions on cleaning a fiber-optic module, refer to
86.

Troubleshooting network connections

•
If a 1-Gbps optic transceiver is inserted into a ICX 6450 device, you must configure the port using the
speed-duplex 1000-full-master command at the interface level.

Digital optical monitoring

NOTE
10 Gbps optical transceivers are not supported on ICX 6430 devices.

Install a fiber-optic transceiver (SFP or SFP+).
Cable the fiber-optic transceiver.
on page 85.
For the indicated port, verify that both ends of the cabling (at the device and the connected
device) are snug.
Verify that the device and the connected device are both powered on and operating correctly.
Verify that you have used the correct cable type for the connection:
‐
For twisted-pair connections to an end node, use straight-through cabling.
‐
For fiber-optic connections, verify that the transmit port on the device is connected to the
receive port on the connected device, and that the receive port on the device is
connected to the transmit port on the connected device.
Use the CLI to verify that the port has not been disabled through a configuration change. If you
have configured an IP address on the device, you also can use the Brocade Network Advisor.
If the other procedures do not resolve the problem, try using a different port or a different cable.
