Characteristic

Description

LEDs

External time synchronization LED

Location

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.

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 SMA port of the external time synchronization connector and the Ethernet link on the PTP port is down.
Constant yellow	The Ethernet link on the PTP port is up.
Flashing green synchronous with the PPS or NT-TS pulse	The Ethernet link on the PTP port is down, and the following condition is fulfilled: When the SMA port of the external 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 PTP port is up, and the following condition is fulfilled: When the SMA port of the external 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.
