Troubleshooting network connections
- 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 Brocade Network Advisor.
- If the other procedures do not resolve the problem, try using a different port or a different cable.
- If a 1-Gbps optic transceiver is inserted into an
ICX 7250 device, you must configure the port using the
speed-duplex 1000-full-mastercommand at the interface level.
