A data center equipment rack, including an electronic equipment enclosure defined by RF-shielded walls. Openings in the RF-shielded walls are provided for being aligned with complimentary-sized and shaped openings in one or more like data center equipment racks and adapted for permitting a shielded electromagnetic connection between two or more racks. At least one access door in the enclosure is provided for facilitating access to the electronic equipment in the rack. Panels are provided for covering the respective openings in the RF-shielded walls when the openings are not being used to permit an electromagnetic interconnection between two or more racks.

A data processing device may include an internal volume that is sealed from space outside the internal volume and an optical system. The optical system may include a first portion, disposed in the internal volume, adapted to receive network data units from devices disposed in the internal volume and a second portion of the optical system. The optical system may also include the second portion, disposed outside of the internal volume, adapted to obtain the network data units from the first portion via an optical connection using transmission at optical frequencies.

A modular remote radio unit assembly that has a frame assembly, electrical components coupled to the frame assembly and configured to provide wireless data transfer, and a single power input for the electrical components. Wherein, when the power input is coupled to a power source, the electrical components are powered to provide wireless data transfer.

A housing device for isolating electromagnetic interference emitting devices includes a structural frame. The structural frame of the housing device is for housing the electromagnetic interference emitting devices. The housing device further includes an electromagnetic interference isolating enclosure. The electromagnetic interference isolating enclosure of the housing device is non-structural. The electromagnetic interference isolating enclosure of the housing device is for encapsulating the structural frame.

A rack system for one or more computing systems is described. The rack system may include support structures, or rack structures, and a housing affixed or un-affixed to the support structures. The rack system may include rails, including telescoping rails, affixed to the support structures and coupled to the computing system. When the rack system is in a closed position, the computing system is positioned within the housing. When the rack system is in an open position, the computing system is removed from the housing and the components of the computing system are accessible. In the open position, only components on one surface of the circuit board are accessible. However, the computing system can rotate, thereby placing the components on the opposing surface of the circuit board in an accessible position. Alternatively, the housing can be affixed to the computing system, and include modifications for access to the computing system.

A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated for housing EMI emitting devices, the internal volume is isolated by at least 80 decibels. The data processing device further includes a thermal management system adapted to control a flow of gas through the internal volume. The data processing device further includes a chassis, adapted to mount to a frame. The chassis includes the internal volume and the thermal management system. The thermal management system is disposed outside of the internal volume.

A back cover module adapted to be disposed on a casing having a back opening is provided. The back cover module includes a fixing bracket, a sliding bracket and a rotating mask. The sliding bracket is slidably disposed on the fixing bracket along a first direction. The rotating mask is pivoted to the sliding bracket. When the fixing bracket is fixed to a position of the casing adjacent to the back opening, the fixing bracket and the sliding bracket are adapted to be inside the casing and a portion of the rotating mask is exposed from the casing. The rotating mask is adapted to follow the sliding bracket and move relative to the fixing bracket toward the first direction to a position out of the casing, and is adopted to rotate relative to the sliding bracket and shield the back opening after being moved out of the casing.

A cassette for insertion and removal of an edge-connected printed circuit card connectable to a server chassis is disclosed. The cassette includes a housing comprising a bottom wall having at least one elongated slot and a catch formed thereon. The cassette further includes a connector sub-assembly overlying the bottom wall having an edge connector socket formed thereon and configured to receive the edge-connected printed circuit card. The cassette further includes a guide sub-assembly underlying the bottom wall having a spring latch formed thereon. The spring latch is operable in a first state to engage the catch to prevent movement of the connector sub-assembly and the guide sub-assembly relative to the housing. The spring latch is operable in a second state to clear the catch to permit the connector sub-assembly and the guide sub-assembly to slide in unison in the at least one elongated slot.

A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated and a communication system, disposed in the internal volume, that: determines a first EMI state of at least one device of devices disposed in the internal volume; makes a determination that the first EMI state is an EMI emitting state; and disables communications by the communication system using a high-speed connection while allowing the communications using a low-speed connection.

A housing device for isolating electromagnetic interference emitting devices includes a structural frame. The structural frame of the housing device is for housing the electromagnetic interference emitting devices. The housing device further includes an electromagnetic interference isolating enclosure. The electromagnetic interference isolating enclosure of the housing device is non-structural. The electromagnetic interference isolating enclosure of the housing device is for encapsulating the structural frame.
