✓USB interface
3. ML4064-MCB-TR Hardware
The subsequent sections cover the essential parts in the hardware, for board operation and
testing.
3.1 Power-Up
To power up the ML4064-MCB-TR 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 (J2) that should be connected to 5V AND 3.3V
taking into account pins distribution, where jumper U1 must be populated
➢Using the banana plug (U8) that should be connected to 3.3V where jumper U2 must
be populated
•Connect the host to your PC using a Type-B mini to Type-A USB cable.

3.3 LED Indicators
The ML4064-MCB-TR includes on-board LEDs, for quick debugging and monitoring purposes.
LEDs are summarized below:
•LED D11 indicates whether a USB cable is plugged or not.
•LEDs D13 and D12, colored green and red, respectively, are used for diagnostic purposes:
✓If D13 is on: USB is locked and device is recognized by the USB driver
✓If D12 is on: USB is not connected or USB driver is not found
✓If both are off: board is not powered correctly or firmware is corrupted
✓If both are blinking: the board is in Bootloader mode
3.4 Low Speed Signals
3.4.1 External I2C
The I2C bus can be accessed externally using U156 pins. In this case a jumper should be
placed on pin header P16 (HW_I2C) shown in the image below.

3.4.2 External HW Control
Also Low Speed Signals are controllable using an external source, this can be done
through J6 (H_LPWN pin) and J7 (H_RSTN Pin) pin headers. In this case a jumper should
be placed on pin header J3 (HW_CTRL) shown in the image below.
Figure 2: External Control Signals
The low speed signals circuit shown below shows the connection of these signals to the
microcontroller and OSFP connector.
Figure 3: Low Speed Signals Schematics
3.4.3 OSFP Connector Pin Access
A pin header connector (J5) is available in the ML4064-MCB-TR, allowing user to access
Low Speed Signals pins (control signals and I2C), and module power nets.
