Two Ethernet PHY status LEDs are integrated into the metal frame of the P2 RJ-45 connector, installed on the top edge and towards the back of the VCU128 board. The two PHY status LEDs are visible within the frame of the RJ45 Ethernet jack as shown in the following figure. As viewed from the front opening, the left green LED is the link activity indicator and the right green LED is the 1000BASE-T link mode indicator.
A separate discrete LED on top of the board (DS19, near item 38 in Figure 1) indicates link established. Details about the tri-mode Ethernet MAC core are provided in the Tri-Mode Ethernet MAC LogiCORE IP Product Guide (PG051). The TI DP83867ISRGZ data sheet is on the TI website.
