7.4 Power Branches
Power branches within the Shelf originate from the PEM and powers all the blades,
the Shelf Managers, and the Fan Trays. The Power is divided in 2 output branches
towards the backplane.
If the joint power capability of all ATCA boards assigned to a branch is
greater than the calculated branch power, the Shelf Manager will not
power-on all boards. (The last plugged-in or the last in the power-up
sequence.)
