Introduction
The ML4041-K is designed to provide an efficient and easy method of programming and testing
100G QSFP transceivers and active optical cables. It includes a complete user-friendly GUI
supporting all features defined by QSFP MSA and simplifying configuration processes to enable
intuitive memory map programming and testing. It is designed to simulate an ideal
environment for QSFP transceivers module testing, characterization and manufacturing.

ML4041-K Hardware
The subsequent sections cover the essential parts in the hardware, for board operation and
testing.
3.1 Power-Up
To power up the ML4041-K host, steps are as follow:
The host TOP is where the cage is mounted
Two options are available to power up the board:
Using the four pins power connector (J43) that should be connected to 5V AND 3.3V
taking into account pins distribution, where the SMD jumper (R60) must be populated
Using the banana plug (U6) that should be connected to 3.3V where the SMD jumper
(R61) must be populated
Connect the host to your PC using a Type-B mini to Type-A USB cable.
