Ethernet Interface Connectors

The NPT-1020 platform provides 12 traffic Ethernet interfaces on its front panel as follows:
4 x 10/100/1000 BaseT interfaces (left-most ports marked P1 to P4) based on RJ-45 connectors with

PoE
4 x 10/100/1000 BaseT interfaces (ports marked P5 to P8) based on RJ-45 connectors without PoE

4 x 100/1000 BaseX SFP based interfaces (ports marked P9 to P12)

In addition the two rightmost connectors are Fast Ethernet RJ-45 type, for management and debug
(marked MNG and DEBUG).
All RJ-45 Ethernet ports support MDI/MDIX auto correction, so both straight and crossed Ethernet cables
can be connected to these ports.
The following figure identifies the connector pins, as seen when looking into the connector. The following
table lists the pin assignment for a typical connector.
