Abstract
An apparatus is disclosed having a controller at each of several network es, each controller monitoring cooling fan output, ambient temperature and electrical load. Each 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.

Apparatus for transferring operating parameters of a first digital computer in response to a request for operating status from a second digital computer connected to said first digital computer through a computer network, the first digital computer being cooled by directing ambient air through the first digital computer, said apparatus comprising:
- monitoring means for monitoring at least one of the electrical load of the first digital computer, ambient temperature of the first digital computer and the rate of airflow through the first digital computer;
- control means responsive to said monitoring means for controlling the airflow rate;
- means for saving the monitored values of at least one of the electrical load, ambient temperature and airflow rate;
- and
- means connected to the computer network for transferring the saved monitored values to the second digital computer.
Apparatus 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 for directing 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 apparatus comprising:
- electrical load monitoring means for monitoring as a first parameter the power being coupled from the switching power supply to the electrical load;
- temperature monitoring means for monitoring as a second parameter the ambient temperature;
- fan speed monitoring means for monitoring as a third parameter the speed of the at least one fan;
- control means for generating a fan speed control signal in response to the monitoring of the power, ambient temperature and fan speed;
- and
- transferring means connected to said monitoring means and said control means, said transfer means being adapted for connection to the computer network for transferring onto the network the value of one of the monitored parameters in response to a network request.
