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
