Production Testing

Overview

The purpose of the test procedure is to identify connectivity issues, poor soldering, and potential manufacturing defects. Some of the issues are directly identified by explicit part-targeted tests, others are implicit, by running adjacent tests.

Required Software

The test image is provided on a pre-configured SD card.

Required Setup

  1. Insert the SD card into the Raspberry Pi.

  2. Connect the Raspberry Pi to a monitor, keyboard, and mouse.

  3. Insert the AD-RPI-T1LPSE-SL on top of the Raspberry Pi.

  4. Connect the AD-APARD32690-SPOE shield on top of the AD-APARD32690-SL board.

  5. Connect the T1L cable to AD-RPI-T1LPSE-SL and the AD-APARD32690-SL board.

  6. Connect the DAPLink cable to the AD-APARD32690-SL board and plug it into the Raspberry Pi.

  7. Power the AD-RPI-T1LPSE-SL using a Type-C power supply (12V).

1) System Test

Type 1 into the terminal then press ENTER to start “1) System Test”. Connect the T1L cable to port 1.

If the test is PASSED, the DUT is functional. Continue testing the other boards.
