? |
PWR : power indicator |
Off |
The switch is powered off. |
|
Green |
Steady on: The power module is supplying power normally. |
||
|
? |
SYS: system status indicator |
Off |
The system is not running. |
|
Green |
- Fast blinking: The system is starting. - Slow blinking: The system is running normally. |
||
|
Red |
Steady on: The system does not work normally after registration,a temperature alarm has been generated. |
||
|
? |
SPED: speed indicator |
Off |
The speed mode is not selected. |
|
Green |
Steady on: The speed mode is selected. In this mode, service port indicators show port speeds. After 45 seconds, the service port indicators automatically restore to the status mode. |
||
|
? |
MODE: mode switch button |
- Press this button once, the service port indicators change to the speed mode and show the speed of each service port. - Press this button again, the service port indicators restore to the default mode and show the connection status of each service port. - If you do not press this button within 45 seconds, the service port indicators restore to the default mode. In this case, the SPED indicator is off. |
