Balanced Technology Extended (BTX) Boxed Processor Specifications
8.1.3 Boxed Processor Support and Retention Module (SRM)
The boxed processor TMA requires an SRM assembly provided by the chassis
manufacturer. The SRM provides the attach points for the TMA and provides structural
support for the board by distributing the shock and vibration loads to the chassis base
pan. The boxed processor TMA will ship with the heatsink attach clip assembly, duct
and screws for attachment. The SRM must be supplied by the chassis hardware vendor.
See the Support and Retention Module(SRM) External Design Requirements Document,
Balanced Technology Extended (BTX) System Design Guide, and the appropriate
Thermal and Mechanical Design Guidelines (see Section 1.2) for more detailed
information regarding the support and retention module and chassis interface and
keepout zones. Figure 43 illustrates the assembly stack including the SRM.
