PASO 5 Disconnecting the MMU2S (part 2)
With a Philips screwdriver, gently loosen the two power terminals located on the
bottom left side of the Einsy board.
The MMU power cable fork connectors are stacked over the main power supply
connectors for the Einsy. Remove only the MMU's fork connectors individually,
leaving the main supply connectors in place.
Using the Philips screwdriver, thoroughly secure the power terminals with the
MMU disconnected. Confirm that all connections match the picture.
Take out the MMU cable bundle from the electronics box. Close the box and secure
it using the M3x40 screw for now.
