Port 1 and Port 2 LED indicators
Notes:
1. Link = On; Activity = Blink; Link/Act = On/Blink; Full Dup/Col = On/Blink;
Full Duplex = On (Full duplex); Off (Half duplex)
Speed = On (100BASE-T); Off (10BASE-T)
2. P1LED3 is ball B3. P2LED3 is ball C3.
Port 1 and Port 2 LED indicators
Note 3: RPT_COL = Blink; RPT_Link3/RX (Host port) = On/Blink;
RPT_Link2/RX (Port 2) = On/Blink; RPT_Link1/RX (Port 1) = On/Blink;
RPT_ACT = On if any activity; RPT_ERR3 (Host port) = On if any CRC error;
RPT_ERR2 (port 2) = On if any CRC error; RPT_ERR1 (port 1) = On if any CRC error;
