Troubleshooting network connections
• 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 Web management interface or Brocade Network Advisor.
• If the other procedures do not resolve the problem, try using a different port or a different cable.
