Ethernet Interface

The Iguana features two on-board Intel 82574IT Gigabit Ethernet controllers. The controllers
provide a standard IEEE 802.3 Ethernet interface for 1000Base-T, 100Base-TX, and 10Base-T
applications. RJ45 connectors are located at locations J22 (Ethernet 1) and J20 (Ethernet 0).
While these controllers are not NE2000-compatible, they are widely supported. Drivers are
readily available to support a variety of operating systems. These interfaces are protected against
ESD damage.

THERNET ONNECTORS
Two board-mounted RJ45 connectors are provided to make connection with Category 5 or 6
Ethernet cables. The 82574IT Ethernet controller auto-negotiates connection speed. These
interfaces use IEC 61000-4-2-rated TVS components to help protect against ESD damage.

THERNET TATUS
On-board status LEDs are provided at locations D7 (single yellow) and D8 (dual green/yellow)
for Ethernet 0, and D9 (single yellow) and D10 (dual green/yellow) for Ethernet 1. These LEDs
provide an indication of the Ethernet status as shown in the following table.
