Module Faults in the RX3i I/O Fault Tables

Powering
connecting/disconnecting the EDS001 from its Ethernet LANs will have effects on both the
CPU and on the affected LANs.
If the EDS001 module fails, the RX3i CPU will record a Loss of Device fault particular to the
EDS001 module at the corresponding rack/slot location. If the rack in which the EDS001 is
located loses Power, and is not the same rack as the CPU, the RX3i CPU will record a Loss of
Device for all devices in that rack, including for the EDS001 module(s) located there.
Adding an EDS001 to an RX3i rack causes the RX3i CPU to register an Addition of Device fault
for the corresponding EDS001 and indicate the rack/slot location involved. Powering up a
rack containing an EDS001 will cause the RX3i CPU to register an Addition of Device fault for
all devices in the rack, including the EDS001.
Pressing the Ethernet Restart push-button has no effect on the Fault Table in the RX3i CPU.
However, all traffic on both LANs will cease to be processed by the EDS001 until such time
as the Ethernet service has been re-established internal to the module. During this time, the
EDS001 module will continue to read data from the RX3i CPU memory, per its DNP3
Outstation configuration. Since no new data will be available to be written to the CPU during
the Ethernet reset period, the EDS001 will present no new data to the RX3i CPU.
Disconnecting an RJ-45 connector from Port 1A or Port 1B will disrupt Ethernet traffic on the
corresponding port. The EDS001 will continue to attempt transmission and will read data
from the RX3i memory per its DNP3 Outstation configuration in order to have fresh data
available for transmission. Since no new DNP3 data will be received during this period, the
EDS001 will present no new data to the RX3i CPU. Once the RJ-45 connector is re-connected,
data exchanges per DNP3 Outstation configuration will resume automatically.
