A link is established with
the remote port and user
packets are being
transmitted or received.

following:
•Verify that the connection to the other network device has
been properly made. Also, make certain that the other
network device is powered on and operating correctly.
•Verify that the port has not been disabled through 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.
•For the combination ports (ports 1~4), check that the
shared SFP port (1F~4F) is not being used.
•If the other actions don’t resolve the problem, try using a
different port or a different cable.

•Verify that the transmit port on the Dell device is
connected to the receive port on the other network device,
and that the receive port on the Dell device is connected
to the transmit port on the other network device. If you are
not certain, remove the two cable connectors from the
port connector and reinsert them in the port connector,
reversing their order.
•Dust may have accumulated in the cable connector or port
connector. For information about cleaning the connectors,
refer to “Cleaning the fiber optic connectors” on page43.
•Verify that the port has not been disabled through a
configuration change.
•Check that the configuration has not forced the use of the
RJ45 port shared with the SFP port.
