Status LEDs
The VCU1525 board is designed to operate with the heat sink and fan enclosure cover
installed. Status light emitting diode (LED) DS3 is a triple-stack LED which is visible through
a cut-out in the PCIe end bracket.
Table 3-7
defines VCU1525 board status LEDs.

User I/O
[Figure
2-1, callout 18]
The VCU1525 board provides these user and general purpose I/O capabilities:
•
4-position active-Low user DIP switch (callout 18) USER_SW_DP[0:3]: SW3
•
DIP switch SW3 (not populated on VCU1525 revision D and later boards)
The FPGA connections for the GPIO are listed in
Board Management Controller
[Figure
2-1, callout 15]
The VCU1525 hosts an MSP432P401RIPZ board management controller (BMC) U19
comprising a MSP432 ARM® Cortex® microcontroller with integrated ADCs and GPIO for
control, monitoring, and sideband communication with the host system and FPGA.
