Abstract: Toolless Compression Attached Memory Module (CAMM) installation systems and methods employ a bolster plate with a generally flat, parallelepiped body portion configured to contact one surface of a CAMM Printed Circuit Board (PCB) and provide compression between the CAMM and a z-axis compression connector. The bolster plate body defines (a) ramped keyhole(s), each ramped keyhole converts lateral displacement of the bolster plate into vertical displacement, providing the compression between the CAMM and the z-axis compression connector, by the ramped keyhole(s) sliding along (a) bottom face(s) of (a) head(s) of (a) fixed standoff(s) extending from an information handling system (IHS) PCB, through the z-axis compression connector and the CAMM PCB. The bolster plate may lock in place, laterally displaced, to maintain the compression between the CAMM and the z-axis compression connector. The bolster plate may also have a flange portion extending generally perpendicular from the body portion.

Abstract: Methods and systems for securing data processing systems are disclosed. A data processing system may be operably connected to other devices via ports. When operably connected, some devices connected via the ports may cause undesired actions to be performed. To limit physical access to the ports, a security apparatus may be used to lock the ports. The security apparatus may transition between states where it may be inserted into openings for the ports and may be locked to the openings for the ports. When so locked, physical access to the ports may be limited.
