General User Interfaces

Table 2–16 shows the configuration DIP switch (S6) signal names and

descriptions.

Board-Specific LEDs

This section describes the two types of board-specific LEDs:

■ FPGA transceiver channel activity LEDs

■ Power, configuration, and traffic activity LEDs

FPGA Transceiver Channel Activity LEDs

In addition to the user-defined LEDs, the board provides a set of 12

yellow LEDs (2 per interface). These board-specified LEDs are used to

display FPGA transceiver channel activity (or traffic) on a XCVR interface

basis for both TX and RX signals.

Table 2–17 shows the channels needing TX and RX LEDs.
