3.2 Mechanical Form Factor
The evaluation board conforms to the ATX form factor. For extra protection in a
development environment, you may want to install the evaluation board in an ATX
chassis. Internal and rear panel system I/O connectors are described in Section 3.4.3.
An overview of connector and slot locations is provided in Section 4.0.
3.3 Thermal Management
The objective of thermal management is to ensure that the temperature of each
component is maintained within specified functional limits. The functional temperature
limit is the range within which the electrical circuits can be expected to meet their
specified performance requirements. Operation outside the functional limit can degrade
system performance and cause reliability problems.
The development kit is shipped with a fansink thermal solution for installation on the
processor. This thermal solution has been tested in an open-air environment at room
temperature and is sufficient for evaluation purposes. The designer must ensure that
adequate thermal management is provided for any customer-derived designs.
3.4 System Features and Operation
The following sections provide a detailed view of system features and operation. Refer
to Figure 2 and Table 7 for the location of the major components of the platform.
