Balanced Technology Extended (BTX) Interface
Chassis Interface to Support and Retention Module
A Support and Retention Module (SRM) is a system component that can be used to support an area of the motherboard and loads upon the motherboard such as loads associated with a thermal module. A SRM can reside in chassis volumetric zone J and also may share chassis zone K as well as the secondary side motherboard zone. A BTX chassis must include interfaces as defined by the features shown in the following figure to provide a standard interface for SRMs. Accordingly a SRM for a BTX chassis and motherboard should be designed to fit into a mate with these features. The interface between the SRM and the motherboard will vary depending on the motherboard and thermal module design.
