Network connection status LEDs
After you install the network cables, you can observe certain LEDs to determine if the network
connections are functioning properly. The table below outlines the LEDs related to the 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.

(Green) The port has
established a valid
link at 10, 100 or
1000 Mbps. Flashing
indicates the port is
transmitting and
receiving user
packets. Off 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 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.
• If the other actions do not resolve the
problem, try using a different port or a
different cable.
