Book Description
Excerpt from Channel Level Power Control Interface: Category Hardware Standard; Subcategory Interface The functional and mechanical specifications are defined for a Power Control Interface which provides a sequential and interlocked means of controlling the power supplied by a computer system power control circuit to attached control units, i/o devices, channel frames, or free-standing storage frames (operating in a remote status) without affecting the power on the rest of the system. By stepping the power (on or off) in discrete system components, the overall power requirements and power surge noise generation are decreased. Several levels of power may exist, depending on the system configuration. Each (central Processing Unit) sequentially provides power, via the Power Control Interface, to each stand alone frame attached to the cpu. Each stand-alone frame (directly attached to the cpu) having units attached a channel with a control unit) sequentially controls the power to each attached unit by means of the Power Control Interface. The Power Control Interface permits the removal of any frame from the system without affecting the power on the rest of the system unless that frame is controlling other frames not shared with other control units. It also provides System Emergency Power Off capability. Foreword (this Foreword is not a part of the Standard, Specifications for Power Control Interface.) This Standard provides the specifications for the functional and mechanical characteristics of a Power Control Interface for a general purpose computer system. The Power Control Interface provides a means of controlling the power supplied by a computer system power control circuit to attached frames (operating in a remote status) without affecting the power on the rest of the system. These attached frames include control units, i/o devices, channel frames, or free-standing storage frames.
