SOM 10/100/1000 Ethernet RJ45 – J9
J9 is a SOM direct connect Ethernet port. The connector is a MagJack L829-1J1T-43 and
contains integrated magnetics and two LEDs for connection indication. The left side LED[1] is
green and indicates link status while the right side LED[0] is amber and indicates link activity.

The SOM’s PHY is routed through JX3 directly to J1. For this reason, the PHY is configured via
the SOM. The PZCC-FMC-V2 net names for this connector interface begin with PETH and are
listed below.
