General User Interfaces
Board-Specific LEDs
This section describes the board-specific LEDs. In addition to the
user-defined LEDs, the board provides a set of 4 yellow LEDs (2 per
interface). These board-specified LEDs display FPGA transceiver channel
activity (or traffic) for both TX and RX signals.
Table 2–17 shows the channels needing TX and RX LEDs.
Status and Channel Activity LEDs
The board provides status and channel activity LEDs, which indicate
successful configuration, power-on status, connection to the HSMC
expansion connector, etc.
Tables 2–18 lists the board status LEDs.
CLK_SEL0 Local oscillator / SMA input select (on = local oscillator) C7
MAX_EN Enables the PFL F2
