Post-assembly:

  • Install display.
  • Install stand-offs.
  • Insert SFP loopback modules into SFP cages to make sure they fit.
  • Glue connectors.
  • Put on heat sinks.

Electrical tests:

  • Check resistors according to the image below:

  • Check output resistances.
  • Power up board with a desktop power supply with a voltage of 12 V and a current limitation of 500 mA. The current reading should be between 250 mA and 300 mA for a board that has never been used.
  • Power off board.

HSIO functional test:

  • Power up board at 12 V and 1.7 A current limit.
  • Attach a Xilinx dongle to J32.
  • Run impact.
  • Right click on FPGA icon and select "Add BPI/SPI flash".
  • The file to download is HsioTest_00000003.mcs .
  • Select BPI PROM 28F00AP30.
  • Right click on the prom icon and select program.
  • After programming you can power down the board and quit impact.
  • Install the following test devices on the board:
    • Loopback SFP modules in SFP0 and SFP1.
    • A loopback QSFP module in QSFP0.
    • 2 SMA cables: One between TXP and RXP, one between TXM and RXM.
    • 2 header test boards in P2 and P3.
    • 1 zone-3 test board.
    • The DTM test module.
    • The TTC module that belongs to this particular board.
  • Attach a USB cable to J30 (GP).
  • Power up the board, again at 12 V and 1.7A.
  • Bring up the serial connection at 115200 Baud with logging of the output to file.
  • Push the COLD-BOOT button on the HSIO and follow the instructions on the screen for testing.
  • Perform both the HSIO and the DTM test.
  • Once the test finishes successfully, quit the serial connection.
  • Upload the logfile to the confluence page for this HSIO.

Cosmic adapter board functional test:

In principle you only have download the firmware onto one HSIO which you can then use to test all interface boards.

  • Power up board at 12 V and 1.7 A current limit.
  • Attach a Xilinx dongle to J32.
  • Run impact.
  • Right click on FPGA icon and select "Add BPI/SPI flash".
  • The file to download is AdapterTest_00000003.mcs
  • Select BPI PROM 28F00AP30.
  • Right click on the prom icon and select program.
  • After programming you can power down the board and quit impact.
  • The rest of the procedure has to be done for each adapter board.
  • Add a jumper to JP2 and JP5 (two center pins).
  • Mount stand-offs.
  • Attach the adapter board to the HSIO.
  • Attach a USB cable to J30 (GP).
  • Power up the board, again at 12 V and 1.7 A.
  • Bring up the serial connection at 115200 Baud with logging of the output to file.
  • Push the COLD-BOOT button on the HSIO and follow the instructions on the screen for testing.
  • Once the test finishes successfully, quit the serial connection.
  • Upload the logfile to the confluence page for this adapter board.
