Abstract

Abstract A method for monitoring various parameters for equipment at network sites. controller at each site monitors cooling fan output, ambient temperature and an electrical load. The controller includes a network interface and microcontroller for responding to requests for the values of monitored parameters. In response to such a request, the controller processes a procedure that retrieves a requested monitored parameter value and that transfers that value onto the network.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 140 words
A method for providing preselected operating parameters of a first digital computer connected in a network in response to a request for operating status from a second digital computer connected in the network wherein the first digital computer includes means for controlling the temperature of the digital computer by directing air having an ambient temperature through the first digital computer, said method comprising the steps of: monitoring at least one of the electrical load of the first digital computer and the ambient temperature of and flow rate of air through the first digital computer; adjusting the airflow past the first digital computer in response to the monitored electrical load, ambient temperature and airflow; saving the monitored values of at least one of the electrical load, ambient temperature and airflow; and transferring the saved monitored values to the second digital computer.
Claim 2
Independent Claim 140 words
A method for providing preselected operating parameters of a first digital computer connected in a network in response to a request for operating status from a second digital computer connected in the network wherein the first digital computer includes means for controlling the temperature of the digital computer by directing air having an ambient temperature through the first digital computer, said method comprising the steps of: monitoring at least one of the electrical load of the first digital computer and the ambient temperature of and flow rate of air through the first digital computer; adjusting the airflow past the first digital computer in response to the monitored electrical load, ambient temperature and airflow; saving the monitored values of at least one of the electrical load, ambient temperature and airflow; and transferring the saved monitored values to the second digital computer.
Claim 3
Dependent Claim 29 words
A method as recited in claim 1 wherein the airflow is generated by at least one variable speed fan and said saving step saves a monitored fan speed value.
Claim 4
Dependent Claim 43 words
A method as recited in claim 2 wherein the electrical load is constituted by a variable load energized by a power supply in response to a load control signal and said saving step includes saving a value corresponding to the load control signal.
Claim 5
Dependent Claim 43 words
A method as recited in claim 1 wherein the electrical load is constituted by a variable load energized by a power supply in response to a load control signal and said saving step includes saving a value corresponding to the load control signal.
Claim 6
Independent Claim 148 words
A method for transferring operating parameters of a digital computer system in response to a request received over a network wherein the digital computer system includes at least one cooling fan that directs cooling air through the digital computer system and a variable electrical load energized by a switching power supply and operated in an environment with a variable ambient temperature, said method comprising the steps of: monitoring as a first parameter the power being coupled from the switching power supply to the electrical load; monitoring as a second parameter the ambient temperature; monitoring as a third parameter the speed of the at least one fan; generating a fan speed control signal in response to the monitoring of the power, ambient temperature and fan speed; and transferring, in response to a received operating parameter request from the network the value of at least one of the monitored parameters.
Claim 7
Independent Claim 148 words
A method for transferring operating parameters of a digital computer system in response to a request received over a network wherein the digital computer system includes at least one cooling fan that directs cooling air through the digital computer system and a variable electrical load energized by a switching power supply and operated in an environment with a variable ambient temperature, said method comprising the steps of: monitoring as a first parameter the power being coupled from the switching power supply to the electrical load; monitoring as a second parameter the ambient temperature; monitoring as a third parameter the speed of the at least one fan; generating a fan speed control signal in response to the monitoring of the power, ambient temperature and fan speed; and transferring, in response to a received operating parameter request from the network the value of at least one of the monitored parameters.
Claim 8
Dependent Claim 37 words
A method as recited in claim 5 wherein the switching power supply operates in response to a pulse-width modulated control signal and said power monitoring step includes measuring the duty cycle of the pulse-width modulated control signal.
Claim 9
Dependent Claim 34 words
A method as recited in claim 5 wherein the at least one fan includes tachometer means for generating a signal indicating fan speed and said fan speed monitoring step includes measuring the tachometer signal.
Claim 10
Dependent Claim 37 words
A method as recited in claim 7 wherein the switching power supply operates in response to a pulse-width modulated control signal and said power monitoring step includes measuring the duty cycle of the pulse-width modulated control signal.
