LED activity
System activity and status can be determined through the activity of the LEDs on the Extension Switch.
There are three possible LED states:
• No light
• Steady light
• Flashing light
Active lights are in one of the following colors:
• Green
• Amber
The status LEDs may display solid amber or flash during boot, POST, or other diagnostic tests. This is
normal; it does not indicate a problem unless the LEDs do not indicate a healthy state after all boot
processes and diagnostic tests are complete.
LEDs on the port side of the Extension Switch
The port side of the Extension Switch has the following LEDs:
• One system status LED (above) on the left side.
• One power status LED (below) on the left side.
• Management Ethernet port speed and activity LEDs.
• One port status LED for each Fibre Channel port on the Extension Switch. The port LEDs are located
in the array in the same relative positions as the ports.
• One port status LED for each optical GbE port.
• Two LEDs for each fixed copper RJ-45 GbE port, one activity/status LED and one fault LED.
