摘要： Apparatus and method for implementing a local proactive hot plug request/acknowledge scheme is disclosed. In a preferred embodiment, each hot pluggable device installable on a computer bus, such as a SCSI bus, is provided with a physical user interface comprising a mechanical request initiator, such as a button or two-position switch, for allowing a user to generate a hot swap request to a controller associated with the bus prior to actual installation of the device on, or removal of the device from, the bus. Upon receipt of the request, the controller determines whether the requested action may be performed, provides a visual indication of its determination to the user via an LED on the user interface and, if installation or removal is determined to be prudent, performs the hot installation/removal in an orderly manner so as not to adversely affect ongoing system operations.

摘要： A sensor circuit for monitoring the operation of a fan in an electronic device includes a current sensor that produces a voltage signal proportional to the magnitude of the current flowing through the fan. The proportional voltage signal is filtered to extract an rms dc signal that then is compared with a minimum and maximum voltage threshold in two voltage comparators. If the voltage of the filtered signal exceeds the maximum threshold value, or is less than the minimum threshold value, a fan failure signal is generated and transmitted to an external monitoring unit. The sensor circuit can be implemented with a standard two-wire fan and interface connector.
