• Verify that the port has not been disabled by a configuration change. You can use the CLI. If you
have configured an IP address on the device, you also can use the Web Management Interface
or Brocade Network Advisor.
• 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 device is connected to
the transmit port on the connected device.
• For copper ports, you can test the cable using Virtual Cable Testing. For more information, refer
to the chapter Monitoring Hardware Components in the FastIron Configuration Guide.
• If the other procedures do not resolve the problem, try using a different port or a different
cable.
Support for digital optical monitoring
You can configure your Brocade device to monitor optical transceivers in the system, either globally
or by specified ports. When this feature is enabled, the system monitors the temperature and
signal power levels for the optical transceivers in the specified ports. Console messages and syslog
messages are sent when optical operating conditions fall below or rise above the XFP or SFP
manufacturer’s recommended thresholds. For details about this feature and how to configure it,
refer to the FastIron Configuration Guide.
