J5A/B – Dual Gigabit Ethernet Interface
This connector provides two three speed Ethernet (TSE1 and TSE2) interfaces (10/100/1000
mega-bit operation) for application communications interfacing. This is a dual RJ45 connector
with LEDs to indicate the status of the links.
The following figure and table provide pinout and signal information for this interface.

Note ...
The Gigabit PHYs on the VMP3 support automatic MDI/MDIX crossover at all
speeds of operation. Therefore both standard as well as crossed Ethernet
cables can be used with these interfaces.
