System LED

Off

The power is off.

 

Constant red

During start-up: Power is on. The adapter is checking the power supplies.

 

Flashing red

After start-up: The power is on. There is a fatal hardware error.

 

Constant yellow

During start-up: The power is on. The power supplies are working.

 

Flashing yellow

There is a new entry in the hardware log.

 

Constant green

The FPGA is loaded, and the system is running.

Activity LEDs

Off

The driver is not loaded, the Ethernet link is down or the port is disconnected.

 

Constant Green

The driver is loaded and the Ethernet link is up, but there is no RX or TX traffic.

 

Flashing Green

The driver is loaded and there is RX or TX traffic on the Ethernet link

External Time Synchronization LED

Off

No driver is loaded, or no valid PPS or NT-TS signal is detected or generated.

 

Constant Yellow

The Ethernet link on the external RJ45 time synchronization connector is up.

 

Flashing green synchronous with the PPS or NT-TS pulse

The Ethernet link on the externalRJ45 time synchronization connector is down, and the following condition is fulfilled: When the external SMA time synchronization connector is configured as a:

• PPS or NT-TS input connector: A driver is loaded, and a valid PPS or NT-TS signal as relevant is detected.

• PPS or NT-TS output connector: A driver is loaded, and a PPS or NT-TS signal is generated.

 

Yellow with flashing green synchronous with the PPS or NT-TS pulse

The Ethernet link on the externalRJ45 time synchronization connector is down, and the following condition is fulfilled: When the external SMA time synchronization connector is configured as a:

• PPS or NT-TS input connector: A driver is loaded, and a valid PPS or NT-TS signal as relevant is detected.

• PPS or NT-TS output connector: A driver is loaded, and a PPS or NT-TS signal is generated.
