An environment detecting module, for securing a shell of a server, includes a sensing module, configured to sense an environment status by a polling method and generate a sensing signal according to the environment status; a connection module, configured to electrically connect the environment detecting module to a host terminal with a first connection status or a second connection status; and a microcontroller unit, coupled to the sensing module and the connection module, configured to determine a power source of the environment detecting module according to the first connection status or the second connection status, and to determine a first mode or a second mode of the environment detecting module according to the power source.

Provided is a rack, comprising: a plurality of rack units; and a plurality of lockers each housing a different respective subset of the rack units, wherein respective lockers among the plurality comprise: a first respective barrier disposed between a respective pair of the rack units; a second respective barrier disposed between another respective pair of the rack units; a third respective barrier that is orthogonal to the first barrier and the second barrier, the third respective barrier being moveably or removeably coupled to the rack; a respective volume configured to receive one or more computing devices; and a respective lock configured to secure the third respective barrier to the rack in the closed position when in a locked state.

In an open-loop heat removal system for a building such as a data center or a home, cool air is supplied to the building by a chilling unit and hot air is expelled from the building without recycling, recirculating, or re-cooling the hot air. For fire suppression, the system receives temperature reading(s) from temperature sensor(s) and determines whether any temperature reading reaches or exceeds a temperature that indicates presence of a fire. If so, a louver positioned over an inlet module is automatically or programmatically closed, shutting off air supply to the building. The system determines whether the building is under a negative pressure internally. If not, an exhaust fan at the outlet of the building is turned on to create a negative pressure internally. The system determines whether an oxygen level of the building indicates that the fire has been contained. If not, a sprinkler system is activated.

A data center, a rack information handling system (RIHS) delivery kit, and a method provide for removing an RIHS from and delivering an RIHS to a data center. The data center includes an enclosure having a raised floor and a lateral opening. The lateral opening has a bottom edge that is aligned with the raised floor in order to transfer a rack information handling system (RIHS) through the lateral opening for a selected one of: (i) removing the RIHSs from the raised floor; and (ii) delivering the RIHS to the raised floor. The data center includes a pallet interface coupled to or integrated into an exterior edge of the raised floor and vertically presented to abut and engage a lateral edge of a roll-off rack shock pallet that supports the RIHS during transport.

Systems, devices, and methods of protecting sensitive equipment against vibrations, mechanical shocks, and earthquakes. A support device includes a lower fixed or non-moving frame, and an upper movable frame. The two frames are connected via four dampers, at or near their four corners; and also by four generally-vertical cables or wires that together with the supported device operate as an inverted pendulum or an upside-down pendulum in response to incoming vibrations or applied forces. The dampers, as well as the inverted pendulum created by the cables, dissipate and absorb vibration energy and mechanical shocks. Optionally, the entirety of the support device has not more than four dampers. Optionally, the entirety of the support device has or not more than eight dampers, wherein four of the eight dampers are not connected to the vertical cables, and four other of the eight dampers are connected to lower ends of the four vertical cables.

The invention relates to a switch cabinet having a housing and a door which is pivotally secured thereto via at least one hinge and has a door leaf, wherein the door leaf has an aperture and a closing element which closes the aperture and is held in a closed position, counter to its mechanical pretension in the direction of its open position, by an electrically controllable locking element.

An electronic equipment rack comprises a frame comprising a plurality of horizontal portions welded to a plurality of vertical portions, and a plurality of weld studs on surfaces of at least one of one or more of the plurality of vertical portions and one or more of the plurality of horizontal portions. One or more additional portions are attached to the frame via one or more of the plurality of weld studs.

A server information handling system is secured by a bezel that couples to an access location, such as an air vent at a front or rear face of a housing. The bezel includes a security structure having a lock and configured to couple directly at the front face or with a bezel extension at the rear face so that the server information handling system can use the same bezel with both a front face or rear face rack mount. The bezel has a lock integrated with the security structure, an air filter that fits over the security structure to filter air flowing into the housing, and a filter brace that captures the air filter by coupling to the security structure over the air filter. The filter brace attaches and detaches at the security structure when the security structure locks a server information handling system housing so that the air filter can be changed while the housing remains secure.

A data center rack system includes a rack housing that includes side panels and a top panel coupled to the side panels, the top and side panels defining a rack volume sized to enclose a plurality of data center server rack trays, each of the data center server rack trays configured to support a plurality of heat generating electronic devices; and a rack bottom coupled to the side panels to at least partially define the rack volume, the rack bottom including a bottom panel having a top surface coupled to the side panels and a plurality of blocks coupled to a bottom surface of the bottom panel opposite the top surface, at least one pair of the plurality of blocks defining an opening between the blocks and below the bottom surface of the bottom panel and sized to receive a lifting member of a lifting machine.

A seismic shim for electronic equipment comprises a base comprising at least a first hole through the base, wherein the first hole is configured to receive a first fastener, and an extension portion extending from the base. The extension portion is perpendicular to the base and comprises at least a second hole through the extension portion, wherein the second hole is configured to receive a second fastener. The seismic shim also comprises a first gusset and a second gusset disposed between the base and the extension portion. The second gusset is spaced apart from the first gusset. The seismic shim is configured for anchoring to an underlying floor structure via the first fastener inserted through the first hole, and is configured for attachment to a surface of the electronic equipment via the second fastener inserted through the second hole.
