Network connection-related LED states TABLE 14
LED Desired
state Meaning Abnormal
state Meaning or action
Ethernet(1-24/48) On or
flashing
(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.
PoE
(1-24/48)
On
(Green) The port is
providing PoE
power to a
connected device. Off A link is not established with the PoE device.
You can do the following:
• Verify that the connection to the other
network device has been properly made.
• If the other actions do not resolve the
problem, try using a different port or a
different cable.
SFP/SFP+(X1 - X4)
for ICX 6450
devices On or
flashing
(Green or
Yellow) The SFP+ port is
operating at 10
Gbps. Flashing
green indicates
the port is
transmitting and
receiving user
packets at 10
Gbps.
Flashing yellow
indicates the port
is transmitting and
receiving user
packets at 1
Gbps.
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 transmit port on the
device is connected to the receive port
on the other network device, and that the
receive port on the 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 page 86.
• Verify that the port has not been
disabled through a configuration change.
• Ensure that the SFP+ in both ends are of
the same optic type (for example. SR,
LR, LRM).
• If the other actions do not resolve the
problem, try using a different port or a
different cable.
