A data center energy management (DCEM) server configures a power supply in the data center. The DCEM server sums input alternating current (AC) power of the power supply to a total AC power of the data center, wherein the total AC power of the data center is a sum of AC power of a plurality of power supplies. The DCEM server sums output direct current (DC) power of the power supply to a total DC power of the data center and reports a ratio of total AC power to total DC power as data center power conversion efficiency. The DCEM server sets a preset power supply efficiency threshold. The DCEM server determines that a real-time power efficiency level is below the power supply efficiency threshold. The DCEM server, responsive to a determination that real-time power efficiency level is below the power supply efficiency threshold, may remedy the power supply.

Example implementations relate to a server device with a capacitive circuit. For example, a server device with a capacitive circuit can include a capacitive circuit located on a printed circuit assembly (PCA) of the server device and a baseboard management controller unit (BMC) to provide a communication interface between the capacitive circuit and a computing device. A voltage can be applied across the capacitive circuit and a signal can be sent from the capacitive circuit to the computing device using the BMC in response to a change in voltage.

A server rack with a plurality of compute nodes is positioned in a facility that includes a spine and the server rack includes a middle of rack (MOR) switch located near the middle of the server rack, vertically speaking. The MOR switch includes a plurality of ports that are connected via passive cables to the compute nodes provided in the server rack. In an embodiment the passive cables are configured to function at 56 Gbps using non-return to zero (NRZ) encoding and each cable may be about or less than 1.5 meters long. An electrical to optical panel (EOP) can be positioned adjacent a top of the server rack and the EOP includes connections to the MOR switch and to the spine, thus the EOP helps connect the MOR switch to the spine. Connections between adjacent server racks can provide for additional compute bandwidth when needed.

A method for managing electrical power to a server or server system is used in a power management system. The power management system comprises a power module, a backup power module, and a server system, the method comprises setting the server system to operate under a first working mode and controlling initialization of a BMC by an initialization command. A specified pin of the BMC is measured for a logic low voltage level and the server system is set to operate under a second working mode if the specified pin of the BMC is at the logic low voltage level. In different modes, the manner of supplying power and the working parameters of the server system are adjusted.

By providing switching units and identification circuits in the smart angled mounting piece, when one or more of the switching units are triggered by the auxiliary member, an identification circuit electrically connected to the triggered switching unit and an identification circuit electrically connected to a switching unit that is not triggered collectively generate a logic signal characterizing the position at which the electronic device is installed to the cabinet, and the logic signal is transmitted to the electronic device through the communication module. The manager may know the position of the current electronic device in real time, without the need to specifically provide position acquisition elements on the cabinet, and without the need to install a separate management system on the back-end server, simplifying the difficulty of device management.
