Board Components & Interfaces

Power, Configuration, and Traffic Activity LEDs

The board provides many other special purpose LEDs. For example, a set

of display power status (PWR_ON when illuminated) LEDs as well as

FPGA configuration status LEDs (LED_ON if the FPGA is programmed).

Additionally, two other LEDs are provided to display traffic activity as

well as link status on GigE on the RJ-45 jack. Table 2–18 shows the

transceiver interface and LED colors.

Standard

Communication

Ports

The board supports the following communication ports discussed in this

section:

■ PCIe edge connector interface

■ Gigabit Ethernet interface

■ SFP module interface

■ High-speed Mezzazine card interfaces (A and B)

■ JTAG interface

PCI Express Edge Connector Interface (J9)

The board features a x8 PCIe edge connector. The high speed PCIe signals

are directly routed to two Stratix II GX device transceivers quads. The

PCIe signals have 100 differential traces terminated on the receive-side
