Table 2–23 lists the general LED component reference and the manufacturing
information.
HSMC LEDs
Each HSMC port has two LEDs located nearby. There are no board-specific functions
for the HSMC LEDs. The LEDs are labeled TX and RX, and are intended to display
data flow to and from the connected HSMC daughtercards. The LEDs are driven by
the Arria V GX.
Table 2–24 lists the HSMC LED schematic signal names and their corresponding
Arria V GX pin numbers.
Table 2–25 lists the HSMC LED component reference and the manufacturing
information.
PCI Express LEDs
Board references D16 through D19 are four PCI Express LEDs for link width
indication. There are no board-specific functions for the PCI Express LEDs. You can
configure the LEDs to display the functions as listed in
Table 2–26 . The LEDs are
driven by the Arria V GX.
Table 2–26 lists the PCI Express LED schematic signal names and their corresponding
Arria V GX GX pin numbers.
