PowerLogic T300 - HU250 no longer has USB ports: why is that?

Mikel_Beltrán · ‎2022-03-31

It has come to our attention that recently received HU250 units no longer include the mini USB port on the front, the one that is covered by a rubber cap.

(please see attached pic)

We don't normally use this port, but I wanted to ask out of curiosity about this modification, if it's a temporary thing, etc.

Thank you very much.

Hi,

Implemented during the design stage of the product, these ports were never usable to customers, only to R&D.

However, in the context of cybersecurity hardening, it has been decided to completely take them out of the hardware.

Thus, no, this is not a temporary action but a permanent one.
