FC Port Status LEDs
See the following table to interpret the FC port status LEDs.
Table 10: FC SFP+ Port Status LED Patterns during Normal Operation
LED Color Status of Hardware Recommended Action
No light Indicates one of the following:
•
No signal or light carrier (media or
cable) detected.
•
The device may be currently initializing.
•
The connected device is configured in
an offline state.
•
Verify the power LED is on, and check
the SFP+ and cable.
•
Verify the device is not currently being
initialized.
•
Verify the status of the connected
device.
Steady green Port is online (connected to an external
device) but has no traffic.
No action required.
Slow-flashing green (on 1 second; then off
1 second)
Port is online but segmented because of
a loopback cable or incompatible device
connection.
Verify that the correct device is attached to
the switch.
Fast-flashing green (on 1/4 second; then off
1/4 second)
Port is online and an internal loopback
diagnostic test is running.
No action required.
Flickering green The Port is online and frames are flowing
through the port.
No action required.
Steady amber Port is receiving light or signal carrier, but it
is not online yet.
No action required.
Slow-flashing amber (on 2 seconds; then
off 2 seconds)
Port is disabled because of diagnostics or
the portDisable command.
Reset the port.
The portCfgPersistentDisable
command is persistent across reboots.
Fast-flashing amber (on 1/2 second; then
off 1/2 second)
SFP+ or port is faulty. Reset the port.
Replace the SFP+. Must be a Brocade-
branded SFP+.
Interpreting POST Results
Each time the switch is powered on, rebooted, or reset, it performs a power-on self-test (POST). The total boot time with
the POST can be several minutes. The POST can be omitted after subsequent reboots by using the fastboot command
or entering the diagDisablePost command to persistently disable the POST. The success or failure results of the
diagnostic tests that run during the POST can be monitored through LED activity, the error log, or the command line
interface. During the POST, the LEDs flash different colors.
The POST performs the following tasks:
•
Conducts preliminary POST diagnostics.
•
Initializes the operating system.
•
Initializes the hardware.
•
Runs diagnostic tests on several functions, including the circuitry, port functionality, memory, statistics counters, and
serialization.
