All MP300 rackable devices manufactured before the 24th of August 2020.

Issue Details

For all MP300 rackable devices manufactured since the 24th of August 2020, 
there is no more USB controller on the motherboard.

As a result, it is not possible to control MP300 rackable devices using USB cables.
Those devices are dedicated to production tests.
In the manufacturing context, TCP/IP communication is mainly used.


MP300 rackable devices are now delivered with USB-Serial cable. 

At the reception of the equipment, it's necessary to change the IP settings of the device
- to keep the rack mode enable or disable it 
- to change the IP address of the device and adjust it to your company network

After configuration, the device can then be used normally with the help of an ethernet cable.
