Ethernet 

The Bengal features two on-board Intel I210-IT Gigabit Ethernet controllers. The controllers 
provide a standard Ethernet interface for 1000Base-T, 100Base-TX, and 10Base-T applications. 
Drivers are available to support a variety of operating systems. These interfaces are protected 
against ESD damage. 

Ethernet Connectors 

Two Ethernet interfaces are provided at connector locations J7 (Ethernet 0) and J1 (Ethernet 1). 
The I210-IT Ethernet controller auto-negotiates connection speed. VersaLogic cable VL-CBR-
0804 adapts the 8-pin Ethernet connector to an RJ-45 connector. Table 18 lists the pinout of the 
J1 and J7 Ethernet connectors. Figure 16 is a side view of the board showing the Ethernet 
connectors and their pin configurations.
