Port LED States
The port LED indicators show the current status of each port on the ThunderSync5-C16 PD.
| Colour | Behaviour |
|---|---|
| Solid Green | The device is connected, the port is on, and the device is fully charged. |
| Pulsing Green | The device is connected, the port is on, and the device is charging. |
| Yellow | Hub is resetting |
| Purple | A fault condition is present on the port |
| Red | Fatal error |
| LED Off | No device is detected |
Port fault indication
A purple LED on a downstream port indicates that the port has a fault. This can appear on any downstream port (ports 1–16).
To identify which port has a fault and what error flags are set, connect to the hub's firmware CLI over the virtual COM port (see Using When Connected to a Host) and issue the state command:
state
When a port has a fault, an error flag (e) appears in that port's flags in the response. For example, the output below shows port 4 with an overcurrent fault:
>>state
1, 0000, D I, 0, 0, x, 0.00
2, 0000, D I, 0, 0, x, 0.00
3, 0000, D I, 0, 0, x, 0.00
4, 0000, e D I, 0, 0, x, 0.00
5, 0927, A C, 1, 15, x, 0.00
6, 0000, D I, 0, 0, x, 0.00
7, 0000, D I, 0, 0, x, 0.00
8, 0048, A P, 2, 2, x, 0.01
You can query a single port by appending the port number, for example state 4.
