Hardware Preparation and Installation
2.3.2
Power Requirements
The board's power requirements depend on the installed hardware accessories. The following
table gives examples of typical power requirements for +5 V and +3.3 V for a processor running
at 600 MHz without any accessories. If you want to install any accessories, the load of the
respective accessory has to be added to the load of the used board variant. For information on
the accessories' power requirements, refer to the documentation delivered with the respective
accessory or ask your local representative.

Power Requirements
(not transition module or PMC)
Power available for PMCs/ transition
modules (see note after table)
The power available for PMCs/transition module values represent the available current
on each power rail and do not guarantee that thermal or cooling needs are met. You
must evaluate to ensure adequate cooling.
2.3.3
Thermal Requirements
Board component temperatures are affected by ambient temperature, air flow, board electrical
operation and software operation. In order to evaluate the thermal performance of a circuit
board assembly, it is necessary to test the board under actual operating conditions. These
operating conditions vary depending on system design.
While Motorola performs thermal analysis in a representative system to verify operation within
specified ranges (see
the board in your application.
