A link is not established with the remote port. You can do the
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 transmit port on the Brocade device is
connected to the receive port on the other network device,
and that the receive port on the Brocade 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, see
page 45.

If the other actions do not resolve the problem, try using a
different port or a different cable.
The port is not transmitting or receiving user packets. You can
do the following:
•
Check the Link LED to make sure the link is still
established with the remote port. If not, take the actions
described in the Meaning or Action column for the Link
LED.
•
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 IronView.
