Important: If you’re not using a powered transceiver, make sure the
Ethernet connection is secure before cycling power.
ATTENTION: The Ethernet connection must be secure while
the PI system is controlling equipment; otherwise, the EI
module may shut down the system’s power supply.
If the system power shuts down, follow these steps:
1. Make sure Ethernet connection is secure.
2. Cycle power by turning off the power from the power supply and
turning it on again.
Ethernet Heartbeat
The EI module requires the IEEE 802.3 SQE (Signal Quality Error) test
(also known as Ethernet heartbeat). Make sure your Ethernet transceiver is
set with the SQE test enabled. For more information about the SQE test,
see the documentation that came with your transceiver.
