Activity LEDs

State and Color Condition
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.
Note: On an NT200A01-SCC running at 8 × 10 Gbit/s, each of the four Activity LEDs on each 40 Gbit/s port reflects if there is link and/or traffic on the associated 10 Gbit/s port.

System LED

State and Color Condition
Off The power is off.
Constant red During start-up: Power is on. The SmartNIC is checking the power supplies.
Flashing red After start-up: The power is on. There is a fatal hardware error. An entry is created in the hardware log.
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.

External time synchronization LED

State and Color Condition
Off No driver is loaded, or no valid PPS or NT-TS signal is detected or generated on the external SMA time synchronization connector and the Ethernet link on the external RJ45 time synchronization connector is down.
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 external RJ45 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 external RJ45 time synchronization connector is up, 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.

Internal time synchronization LEDs

State and Color Condition
Off No driver is loaded, or no PPS or NT-TS pulse is detected or generated.
Flashing green synchronous with the PPS or NT-TS pulse When the corresponding time synchronization connector is configured as an:
  • Input connector: A driver is loaded, and a valid PPS or NT-TS signal is detected.
  • Output connector: A driver is loaded and a PPS or NT-TS signal is generated.
