CP Box

Model Number: CPBH-100

the NCC page for a Testing Kit for PlayStation 5 mentions a so called "CP Box" it is a black box with a USB C input, USB C output, ethernet and power cable.

There are two modes the CP Box can run in "Engineering Mode" and "Normal Mode"

In engineering mode the CP Box is simply plugged into power, with the USB-C Cable in the PS5.

Engineering Mode NCC Diagram

(the traditional chinese there says "Engineering Mode")

however in Normal mode, the CP Box USB-C Port is plugged into a USB-C Portable Hard Drive, and the Ethernet is plugged into your router / network hub, and the USB-C Cable into the ps5.

Normal Mode NCC Diagram

The "USB Dongle" mentioned here is mentioned in another document to be a USM16CA1 which is a standard USB-C flash drive

on the front of the CP Box it says

   CP INIT
   NETWORK INIT
   
   SPEED
   LINK/ACT
   
   STATUS

Although its unknown at the moment exactly what the CP Box is for - it is to enable dev mode on test and dev kits. possibly the ethernet connection is for checking activation online on DevNet? and the USB Hard Drive maybe for Packages? or games?

Or perhaps its related to the Communication Processor similar to that on the PSVita, maybe its just an external version of it? i dont know ;-;

oh and the the NCC page for the DevKit makes no reference to a "CP Box" it appears to be built into it instead
