Observing LEDs
After you install the network cables, you can observe certain LEDs to determine if the network
connections are functioning properly.
Table 5 describes the LEDs related to network connections,
the desired state of each LED, possible abnormal states of each LED, and what to do if an LED
indicates an abnormal state.
If a problem persists after taking these actions, contact Brocade technical support.

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
uncertain, 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” .
•
If the other actions don't resolve the
problem, try using a different port or a
different cable.

is still established with the remote port.
If not, take the actions described in the
Meaning or Action column for the Link

disabled through a configuration
change. You can use the CLI. If you have
