1. Introduction The ML4062-MCB-LPBK is designed to provide an efficient and easy method of programming and testing 400G QSFP-DD transceivers and active optical cables. It includes a complete user- friendly GUI supporting all features defined by QSFP-DD MSA and simplifying configuration processes to enable intuitive memory map programming and testing.
3.2 Module Power-Up The modules are supplied using one of two powering options: From the on-board regulator that uses the main host supply (P5V) as input From an external 3.3V source through connector (U319), by following the steps below: ...
The image below shows the default jumpers placement for the low speed signals. Figure 2: Default Board Configuration 3.5 LED Indicators The ML4062-MCB-LPBK includes on-board LEDs, for quick debugging and monitoring purposes. LEDs are summarized below: LED D11 for Ethernet operation.
3.6 Low Speed Signals 3.6.1 External HW Control Low Speed Signals are controllable using an external source, this can be done through J7 and J8 pin headers, for modules A and B, respectively. In this case a jumper should be placed on pin header P19 (HW_CTRL) shown in the image below.
Figure 6: Connectors Pin Access 4. ML4062-MCB-LPBK Software The ML4062-MCB-LPBK is accessible and controlled through application software. This software is MSA compliant and provides a user-friendly interface to operate the board and access all its features. The communication between the ML4062-MCB-LPBK board and the software is established through Ethernet connection.
7. Bootloader Accessing in bootloader mode allows the user to reprogram the microcontroller, this is done as described below: 1. Connect a jumper on P15 (Boot_Run) near the microcontroller. 2. Connect a USB cable between the PC and Board. 3. Power up the board. 4.
