System-Level LEDs

LED Description

SYSTEM

The SYSTEM LED shows the status of the switch (system).

 

 

 

 

Off (dark)

Switch is not powered on.

Solid green Switch is healthy.

Blinking green

Switch is running power-on self-test (POST).

Solid amber

Switch is faulty, is rebooting, or is in recovery.

RPS

The RPS LED shows the status of a connected redundant power system (RPS). This LED is available on switches that support an 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

RPS is connected but is unavailable because it is providing power to another device.

Solid amber

RPS is in standby mode or is in a fault condition.

Blinking amber

Switch internal power supply has failed, and the RPS is providing power to the switch.

MASTER The MASTER LED shows the stack master status. This LED is available on switches that have stack ports.

 

 

 

Off (dark)

Switch is not the stack master.

Solid green

Switch is the stack master or a standalone switch.

Solid amber

An error occurred when the switch was selecting the stack master switch or a stack error.

PoE The PoE LED shows the status of PoE being provided to the ports. This LED is 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.

STATUS

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

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

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.

STACK

The port LEDs are in stack mode. This LED is available on switches that have stack ports.

 

 

Off (dark)

The port LEDs are not showing stack member status.

Solid green

The port LEDs are showing stack member status.

MGMT The Ethernet Management Port LED shows the status of the Fa0 port. This LED is available only on the Catalyst 2960-S switches.
 

Off (dark)

No link is present on the port.

Solid green

Link is present between the port and management station.

PD The PD (Powered Device) LED shows the status of power being supplied from an uplink switch port to a PoE device that is connected to a downlink switch port. This LED is available only on the Catalyst 2960-C switches.
 

Solid green

Power from the uplink switch port is sufficient to power the PoE device.

Solid amber

Power from the uplink switch port is not sufficient to power the PoE device.

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.

By default, the port LEDs show port status. To display the other modes 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.
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 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. This LED is 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 status. This LED is available on switches that have stack ports.
 

The STACK LED is off (dark)

Stack mode is off.

Blinking green

Port number means stack member number.

Solid green

Stack cable is connected.

Solid amber

Stack cable is not connected.
