A security device for a universal emergency power-off (UEPO) switch of a computer system enclosure involves a plate body having a first and second portion, the first portion has a length and width sufficient to allow it to be rigidly constrained, the second portion has: a hand grip near an end of the second portion including surface texturing sufficient to capture and retain epithelial cells from a person who grips the hand grip to gain access to the UEPO switch. The plate body also has a deformation region such that, when the first portion is rigidly constrained, application of a force, directed within a range from 0&#xb0; to about 45&#xb0; from a right angle to the surface, will cause plastic deformation of the plate body within the deformation region.

Universal emergency power-off switch security device

A security device for a universal emergency power-off (UEPO) switch of a computer system enclosure involves a plate body having a first and second portion, the first portion has a length and width sufficient to allow it to be rigidly constrained, the second portion has: a surface including multiple openings to allow for ventilation while substantially impeding access to the UEPO switch, a port through which system identification information can be viewed, and a hand grip near an end of the second portion including surface texturing sufficient to capture and retain epithelial cells from a person who grips the hand grip. The plate body also has a deformation region such that, when the first portion is rigidly constrained, application of a force, directed within a range from 0&#xb0; to about 45&#xb0; from a right angle to the surface, will cause plastic deformation of the plate body within the deformation region.

An input/output cable port assembly and electromagnetic interference (EMI) attenuation method are provided. The port assembly includes a cable port structure for an electronics rack with an opening for input/output cables to pass therethrough, and a first and a second partition. The first and second partitions couple to the cable port structure and reside within the opening. The first partition includes at least one ferrite inductor portion and the second partition includes at least one second ferrite inductor portion. The partitions are configured to be disposed adjacent to each other as adjoining partitions within the cable port structure, and when disposed as adjoining partitions, the first and second ferrite inductor portions mate and define a ferrite inductor with a central opening for input/output cable(s) of the electronics rack to pass. The ferrite inductor attenuates electromagnetic interference resulting from transient or steady state currents on the cable(s) passing therethrough.

Ferrite inductors integrated within input/output cable port assembly of an electronics rack

An input/output cable port assembly and electromagnetic interference attenuation method are provided. The cable port assembly includes a cable port structure mounted to an electronics rack with an opening for input/output cables to pass therethrough, and multiple bottom ferrite inductor portions and multiple top ferrite inductor portions. The bottom and top ferrite inductor portions include first and second surfaces, respectively. The inductor portions are configured to be stacked within the cable port structure with their first and second surfaces in opposing relation to define at least one ferrite inductor with a central opening defined by the first and second surfaces for input/output cable(s) of the electronics rack to pass. The ferrite inductor attenuates electromagnetic interference resulting from transient or steady state current on the cable(s) passing therethrough.
