Silver Network data path connections
In the standard Silver Network setup, a point to point loop configuration is used for network
communications.

CAUTION
The PoE NIC is intended to supply power only to the processor on
which it is mounted. Do not attempt to power an auxiliary device with
the PoE NIC.

The PoE NIC power output must be
connected to the processor’s power
input. The processor in turn supplies
power to the PoE NIC via the
expansion header.
If non-PoE Ethernet is used, an
alternate source of DC power must be
connected to the processor.
