Abstract: A method of servicing a computer system without interrupting operation of the computer system, by connecting a computer component to a board of the computer system, detecting connection of the computer component to the system board using a control circuit, supplying power to the voltage input of the computer component in response to detecting the connection, and thereafter monitoring the power supplied to the voltage input of the computer component. The method may be used for core computer components such as CPU modules and voltage regulator modules. Power to the voltage input of the computer component is turned off in response to a determination that a current level of the power supplied to the voltage input exceeds a specified level. A fault signal is latched in an active state in response to the determination; the fault signal is reset when the component is removed from the system. The method also applies to a plurality of hot-pluggable components, wherein the power supplied to each component is individually monitored.

Abstract: A communication adapter circuit (10) is connected to a processor through processor I/0 interface buses (12, 14). Data and control signals are provided through the buses (12, 14) to a timer circuit (18), a programmable peripheral interface circuit (20), an asynchronous and bisynchronous control circuit (22) and an SDLC/HDLC control circuit (24). Each of the control circuits (22, 24) includes parallel-to-serial and serial-to-parallel conversion circuitry. A clock select circuit (32) operates in conjunction with the timer circuit (18) and the programmable peripheral interface circuit (20) to establish a data transmission rate for the data flow through the adapter circuit (10). From the control circuits (22, 24) the data is transmitted through a modem interface bus (44) to a dual modem switch (56). From the switch (56) the data is transmitted to either an EIA RS 232 interface circuit (60) to a conventional modem or through a bus (64) to an internal modem. A phase locked loop circuit in the control circuit (24) generates a data clock signal on a line (33) for operation of the adapter circuit (0) in the bisynchronous protocol with a non-clock-generating modem.

Abstract: A communication adapter circuit (10) is connected to a processor through a data bus (12)and a control bus (14). Data and control signals are provided through the buses (12,14) to a timer circuit (18), a programmable peripheral interface circuit (20), an asynchronous and bisynchronous control circuit (22) and an SDLC/HDLC control circuit (24). Each of the control circuits (22, 24) includes parallel-to-serial and serial-to-parallel conversion circuitry. A clock select circuit (32) operates in conjunction with the timer circuit (18) and the programmable peripheral interface circuit (20) to establish a data transmission rate for the data flow through the adapter circuit (10). From the control circuits (22, 24) the data is transmitted through a bi-directional serial line (44) to a dual modem switch (56). From the switch (56) the data is transmitted to either an EIA interface circuit (60) to a conventional modem or through a line (64) to an internal modem.
