3.4.3 Front Panel (RJ-45) Ethernet Interface
he HW400c/2 board lded RJ-45 (with integrated transformer
nd two s) located at the front panel that provides an Ethernet LAN
terface. The port is auto-negotiating and auto-sensing, and operates at 10/100/1000
bps. The left LED (looking at the port) indicates Link/Activity/Speed and the right
ED indicates collision detection (See Figure 12).

gisters Initialization and Monitoring
The switch is initialized and its registers polled by utilizing its SPI bus interface.
This interface is connected through the CPLD. For a description of how to access the
SPI interface, please refer to Section 4.4.
