Abstract: A power management method for a server system is provided. At least any one of a power status indication signal and an alert signal from a power supply is detected to judge whether an input voltage is normal. If it is judged that the input voltage is abnormal, a motherboard sends the power status indication signal to a battery backup unit (BBU) to inform the BBU to supply power to the motherboard. If it is judged that the input voltage is abnormal, the motherboard lowers its loading.

The power supply is adjacent to the rear side of the rack. The switch is adjacent to the front side of the rack. Each of the servers is disposed in one of the other rack units and electrically connected to the power supply module and the switch.

Abstract: A rack server system and an operating method applicable thereto are provided. The rack server system includes a battery backup unit (BBU) and at least one server. The operating method includes: communicating the server and the BBU with each other; the BBU providing a status information and a previous self-discharging test information to the server for the server to judge a status of the BBU; and providing power from the BBU to the server and adjusting a loading of the server according to the status information of the BBU when an input power is interrupted.

Abstract: A server includes a casing, a bottom plate, a first hard disk module, a second hard disk module, and a lifting device. The bottom plate is disposed in the casing and configured to be sliding relative to the casing. The first hard disk module is movably disposed on the bottom plate. The first hard disk module includes a track. The second hard disk module is fixed on the bottom plate and disposed behind the first hard disk module. The lifting device moves up the first hard disk module when the bottom plate is pulled out of the casing, and the lifting device moves down the first hard disk module when the bottom plate is pushed into the casing. A drawer lifting device is also disclosed.

Abstract: A hard drive tray device applied in a server is provided. The server includes a housing. The hard drive tray device includes a rail member and a tray. The rail member is disposed at the inner wall of the housing. The tray is slidably engaged with the rail member so as to slide between an expanded position and a closed position relative to the housing. The tray includes a base for carrying two storage devices. The base has a hollow portion. The storage devices are respectively located at two sides of the hollow portion. When the tray slides to the expanded position, one of the storage devices and at least a part of the hollow portion are located outside the housing.

Abstract: A flat display system includes a first flat device and a second flat device. The second flat device communicates with the first flat device via wireless communication. When the first flat device is located within a predetermined distance from the second flat device, the first flat device is transformed into an input device of the second flat device.

Abstract: A power server system is disclosed. The power server system comprises a power transmission interface, a power supply and a battery backup unit (BBU). The power supply converts an AC power into a DC power and outputs the DC power to the power transmission interface. After the AC power is disconnected, the power supply continues outputting the DC power in a holding period having an arising period and a current sharing period. The BBU outputs a redundant power to the power transmission interface before the power supply stop outputting the DC power. The BBU boosts the voltage level of the redundant power in the arising period, and controls the voltage level of the redundant power to be the same with that of the DC power in the current sharing period, so that the battery output inrush current is reduced and the battery life is extended.

Abstract: A server system is disclosed. The server system comprises a motherboard and a server power system. The server power system comprises a power transmission interface, a power supply, a battery backup unit (BBU) and a signal transmission interface. The power supply converts an AC power into a DC power and then outputs the DC power to the motherboard via the power transmission interface. The BBU provides parallel or redundant power to the motherboard via the power transmission interface. The BBU and the power supply have the same size. The signal transmission interface is electrically connected to the motherboard, the power supply and the BBU.

Abstract: A server rack system including a plurality of power supply units, a monitoring circuit, a rack management controller (RMC), and a plurality of server nodes is provided. The monitoring circuit is for monitoring the power supply units. The RMC is for monitoring the power supply units. When the monitoring circuit and/or the RMC finds that at least one of the power supply units failed to output a normal voltage, an operation status of the server nodes is lowered or at least one of the server nodes is forcibly shut down.

Abstract: A rack server system including at least one server and a battery backup unit (BBU) is provided. A power supplier is coupled to the server for converting an input voltage into a first output voltage when the input voltage is normal and for providing the first output voltage to the server. The BBU is coupled to the server and the power supplier for detecting the first output voltage outputted from the power supplier and for providing a second output voltage to the server when the input voltage and/or the first output voltage are abnormal.

Abstract: A rack server system and a control method thereof are provided. The rack server system establishes a communication link for communicating with a battery backup unit. The battery backup unit is connected to a power input port of the rack server system, and includes a number of battery modules connected with each other in parallel. The rack server system controls the battery backup unit to perform validity test on a first battery module during a first period and to perform validity test on a second battery module during a second period, wherein the first period and the second period are not overlapped with each other.
