Figure 56: Silver Network Ethernet wiring connections
Silver Network data path connections
In the standard Silver Network setup, a point to point loop configuration is used
for network communications. Figure 57 below shows the processor to processor
network connections for the EIA-422 and fiber optic communication options.
Figure 58 on page 50 illustrates an EIA-422 based Silver Network and Figure 59
on page 51 shows a fiber optic based Silver Network. Silver Network's using
Ethernet communications use a star configuration. Figure 60 on page 51
illustrates an Ethernet based Silver Network (Star configuration) and Figure 61
on page 52 shows a Silver Loop + Ethernet configuration in which two
processors are connected to the NMS via Ethernet NICs and a PoE switch, and
then communicate with other processors via the sensor cables.

T4 processor power input
The PoE NIC typically receives power over
its Ethernet connection. It provides power
to the processor through T4, the processor
power input. The processor then supplies
power to the NIC through the expansion
header. If the PoE NIC is not receiving
power over its Ethernet connection, the
processor must have another source of DC
power connected to T4.
Connect the PoE NIC ground strap to a
ground lug on the enclosure.
Connect the enclosure ground lug to a
nearby approved earth ground.
