Off (dark)

The switch is not powered on.

Solid green The switch is healthy.

Solid amber

The switch is faulty, is rebooting, or is in recovery.

STATUS

This LED shows that the port LEDs are in port status mode. This is the default mode.

 

 

Off (dark)

The port LEDs are not showing port status.

Solid green

The port LEDs are showing port status.

DUPLEX

This LED shows that the port LEDs are in port duplex mode.

 

 

Off (dark)

The port LEDs are not showing the port duplex mode.

Solid green

The port LEDs are showing the port duplex mode.

SPEED

This LED shows that the port LEDs are in port speed mode.

 

 

Off (dark)

The port LEDs are not showing the port speed.

Solid green

The port LEDs are showing the port speed.

RPS

The RPS LED shows the status of a connected redundant power system (RPS).

 

 

 

 

 

Off (dark)

RPS is off or is not properly connected.

Solid green

RPS is connected and is ready to provide back-up power.

Blinking green

Port States

LED Mode Description
Status

In this mode, the port LEDs show port status, port duplex mode, and port speed.

By default, the port LEDs show port status. To display the port duplex mode and the port speed from the port LEDs, you must use the View list from the device manager or the Mode button on the physical switch.

 

Off (dark) No link.
Solid green Link is up, but there is no activity on the link.

Solid brown

Port is administratively disabled.

Yellow Port is error disabled.
Blinking green and amber Link is faulty.
Solid amber Port is faulty, is disabled due to an error condition, or is in an STP-blocked state.
Duplex

In this mode, the port LEDs show the duplex mode (full duplex or half duplex) of the ports.

Note: The 10/100/1000 ports operate only in full-duplex mode.

 
Off (dark) No link.
Solid light blue Port is in half-duplex mode.
Solid green Port is in full-duplex mode.

Speed

In this mode, the port LEDs show the operating speed (10, 100, or 1000 Mb/s or 10 Gb/s) of the ports.

 

 

 

 

Off (dark)

No link.

Solid light blue

10 Mb/s.

Solid green

100 Mb/s.

Blinking green

1000 Mb/s.
