3.4 SSI Compliance
If your motherboard is intended to meet Server System Infrastructure (SSI) Specifications, it must
meet a minimum set of requirements. All requirements from the Entry-level Electronics-Bay
Specification: A Server System Infrastructure (SSI) Specification for Entry Server Version 3.0
(SSI EEB) are highlighted here. Where anything conflicts with the SSI specification, the SSI
specification supersedes this document.
3.4.1 Mounting Hole Placement
The SSI Specification requires that every SSI compliant chassis provides a mounting hole at each
of the locations enumerated in Figure 3-5. Pedestal Server chassis typically provide stand-offs for
each of these mounting holes. The baseboard manufacturer can choose to use any of the mounting
holes by simply removing the un-needed stand-offs. However, in a 2U rack mount chassis, there is
not enough vertical room for removable standoffs. A system integrator must work with the chassis
manufacturer to ensure that mounting holes are provided for only those chosen by the baseboard.

Holes Supported by the Chassis. All dimensions are in inches.
