MULTIPORT ENERGY SUPPLY FOR A NONVOLATILE MEMORY MODULE

A power module for a computer system includes an internal source of stored energy and a group of interface ports, including a management port and non-management ports. The management port provides a control interface to control the power module. The non-management ports each lack the control interface of the management port, and each provide a signal indicating that the power module has a sufficient amount of the stored energy to power a defined operation by external devices coupled to and drawing power from said non-management ports. The management port will typically provide a similar signalto the coupled management device. The signal may be implemented as a high or low voltage level on a serial interface cable pin. 种用于计算机系统的电源模块，包括存储能量的内部源和组接口，包括管理端口和非管理端口。所述管理端口提供控制接口以控制所述电源模块。所述非管理端口每个缺少所述管理端口的所述控制接口，并且每个提供指示所述电源模块具有足够量的所述存储能量的信号以通过耦合到所述非管理端口并且从所述非管理端口汲取功率的外部设备进行的定义操作供电。所述管理端口将通常向耦合的管理设备提供类似的信号。所述信号可以在串行接口电缆引脚上实现为高电平或低电平。
