System LEDs
LED | Description
SYSTEM | This LED shows the status of the switch (system).
|  | 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 | 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.

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.
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.

Back to Top Color-Wavelength Representation in CWDM Module Ports Note The circles in the icon for a coarse wavelength-division multiplexer (CWDM) module port can be any of the eight colors, each denoting a different wavelength. This table shows the wavelength that is denoted by each color. To see the wavelength 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
