Ethernet UnitIndicator Description of Ethernet card

No. Silkscreen Description Remarks

1 - Network interface running indicator

The indicator (yellow) is on when data is passing by the network interface link.

2 - Network interface link indicator

The indicator (green) is on when the network interface connects with a network cable.

On for 100ms and off for 100ms: The board is not in service.

On for two seconds and off for two seconds: The board is offline.

On for one second and off for one second: The board works normally.

Off: No alarm.

Flash three times every other second: Critical alarm.

Flash twice every other second: Major alarm.

Flash once every other second: Minor alarm.

The alarm indicator and the running indicator are on for one second and off for one second at the same time: Waiting for loading software.

The alarm indicator and the running indicator are on for 100ms and off for 100ms at the same time: Loading software.
