Port LEDs
The LED array on the front panel displays information about all the Ethernet links on the board. A
green/amber two-color LED is used for each of the 26 Ethernet port connections (24 10/100 + 2
Gigabit). A push-button switch just below the array toggles the LED display from Link /Activity
mode to Link / Speed mode. The default LED mode is Link /Activity. When you depress the switch
button, the LEDs are in Link/Speed mode.

Solid Green Good connection, link present.
Blinking Green Port is transmitting or receiving packets (activity is on going).
Solid Amber
Port is not forwarding packets. The port has been disabled by management, an
address violation has occurred, or the port is being blocked by STP.
Note: After a port is reconfigured, the port LED can remain amber for as long as
30 seconds while STP checks the switch for loop paths. When the STP checking
is completed, the port then resumes displaying its current connection status.
