### 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.
| 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).
|  | 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.
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.

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.
| 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.
|  | 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.
| 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.
|  | 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.

Back to Top ### Color-Wavelength Representation in CWDM Module Ports Note: The circles in the icon for a coarse wave length-division multiplexer (CWDM) module port can be any of eight colors, each denoting a different wave length in nanometers (nm). This table shows the wave length that is denoted by each color. To see the wave length of a CWDM module port, point to its icon.
Color | Wave Length
| Gray | 1470 nm
| Violet | 1490 nm
| Blue | 1510 nm
| Green | 1530 nm
| Yellow | 1550 nm
| Orange | 1570 nm
| Red | 1590 nm
| Brown | 1610 nm
