A dual-input power supply has two power paths that connect a server to electrical Each power path has a first stage that comprises a power-factor correction circuit. The power paths share a common second stage that comprises a dc/dc converter. The first stages of the power paths collectively defining a pair of first stages that is disposed either within a package that is off the motherboard or without a package and on the motherboard. Similarly, the second stage is disposed either within a package that is off the motherboard or without a package and on the motherboard.

Technologies for providing shared memory for accelerator sleds includes an accelerator sled to receive, with a memory controller, a memory access request from an accelerator device to access a region of memory. The request is to identify the region of memory with a logical address. Additionally, the accelerator sled is to determine from a map of logical addresses and associated physical address, the physical address associated with the region of memory. In addition, the accelerator sled is to route the memory access request to a memory device associated with the determined physical address.

A method and apparatus (“utility”) for facilitating connection of rack-mounted data devices (50) to a data network is provided. The utility includes a distribution strip (42) and a number of network ports (44), disposed on the distribution strip (42), for use in connecting the rack-mounted data devices (50) to the network. The distribution strip (42) has a longitudinal axis, and is disposed on a rack (40) such that a length of the distribution strip (42), defined relative to the longitudinal axis, extends primarily or exclusively along a vertical axis of the rack (40). The distribution strip may further include a data network switch device. A utility is also provided that provides improved redundancy with regard to connections of rack-mounted data devices by including a distribution strip (42) that includes first and second ports (46) for connecting the distribution strip (42) to a network device (56).

A backup battery system includes a charging-discharging module and a battery module. The charging-discharging module includes a first connector and a first engaging member. The battery module is detachably connected to the charging-discharging module and includes a second connector corresponding to the first connector and a second engaging member corresponding to the first engaging member. When the battery module is connected to the charging-discharging module, the first connector is joined with the second connector and the first engaging member is fixed to the second engaging member.

A sensor may detect a coolant leak at or near an appliance that is slidable between a seated position and an ejected position relative to a rack. In the seated position, a coolant supply line may be coupled with a conduit of the appliance to convey coolant past the appliance. A biaser can bias the appliance toward the ejected position, and a latch may secure the appliance in a seated position against the biaser. A releaser can release the latch in response to coolant leak detection by the sensor and permit the biaser to move the appliance toward the ejected position, for example, which may cause the conduit to become disconnected from the coolant supply line to cut off flow to the leak.

An uninterruptible power supply system includes a plurality of functional modules interconnected to form a power distribution network coupling at least two power sources to a load. Each functional module has at least two ports coupled to at least one other of the functional modules and/or to at least one other external device and includes a control circuit configured to autonomously control at least one function relating to electrical power transfer between the at least two ports. The system further includes a controller module configured to communicate with each of the functional modules over at least one digital communication link to control power flow between the at least two power sources and the load.

A connector for use in a free-standing connector port for mating with an external pluggable module is disclosed. The connector has terminals that extend lengthwise of the connector so that cables may be terminated to the terminals and the terminals and cable generally are horizontally aligned together. The connector includes a housing and a pair of connecting elements that flank a card-receiving slot of the connector. The cables exit from the rear of the connector elements and from the connector port. The connector elements engage the connector port to fix the connector in place within the connector port.

A cable backplane system includes cable backplanes each including a tray configured to be coupled to a chassis and a plurality of cable connector assemblies mounted to the tray. The tray has a plate extending between a front and a rear with mounting locations receiving corresponding cable connector assemblies. The trays are oriented parallel to each other with front openings between the fronts of the plates and rear openings between the rears of the plates. Each cable connector assembly has a housing holding contacts terminated to corresponding cables. Each cable connector assembly has a holder mounted to the corresponding mounting location of the plate. The holder is mounted to the plate and removable from the plate through the rear opening at the rear of the plate.

A server node connection system uses two or more proximity sensors per server node to determine progressive, real time changes in wipe length for each individual connector on the node that is connected to an opposing header connector on header connected to a midplane of the server assembly/rack. The system is capable of scanning, monitoring, trending, and alarming.

According to one embodiment, an automatic transfer switch (ATS) module for an electronic rack includes a container and four pairs of relays that are disposed within the container, each pair having a first relay connected in series with a second relay. A first two pairs of relays are arranged to connect to a first power source and are arranged to connect to a power supply unit, and a second two pairs of relays are arranged to connect to a second power source and are arranged to connect to the power supply unit. The four pairs of relays are arranged in one of several open-closed configurations, such that in a first open-closed configuration the first source connects to the power supply unit through a first two pairs of relays and in a second open-closed configuration the second source connects to the power supply unit through a second two pairs of relays.
