STAT

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

 

 

Off (dark)

The port LEDs are not showing port status.

Solid green

The port LEDs are showing port status.

SPEED

The SPEED LED shows that the port LEDs are in speed mode.

 

 

Off (dark)

The port LEDs are not showing the port speed.

Solid green

The port LEDs are showing the port speed.

PoE The PoE LED shows that the port LEDs are in PoE mode. PoE features are available on switches that have PoE ports.

 

 

 

Off (dark)

PoE to the ports is off.

Solid green

One or more ports is receiving PoE.

Blinking amber

One or more ports is not receiving PoE because of a fault.

STACK

This STACK LED shows that the port LEDs are in stack mode.

 

 

Off (dark)

The port LEDs are not showing stack member status.

Solid green

Port-Level LED States

LED Mode Description
Status

In this mode, the port LEDs show port status, port duplex mode, port speed, PoE status, and stack status. PoE features are available on switches that have PoE ports.

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.
Blinking green

Link has activity.

Solid brown

Port is administratively disabled.

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

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.

Fast blinking green 10 Gb/s.
PoE In this mode, the port LEDs show the status of the Power over Ethernet (PoE) ports. PoE features are available on switches that have PoE ports.
 

Off (dark)

No power is allocated.

Solid green

Power is allocated.

Blinking green and amber Power is denied (to prevent exceeding power capacity).

Blinking amber

Port is disabled due to a fault condition.

Solid amber Port is administratively disabled.
Stack In this mode, the port LEDs show the switch stack and stack member status.
 

Off (dark)

Stack mode is off.

Blinking green

Port number means stack member number.

Solid green
