Abstract: Automatic monitoring of a cooling system and providing warnings of abnormal operation. The cooling system includes one or more air handling units to provide air flow cooling to a plurality of racks of computer equipment, each rack having a display module for indicating an inlet air temperature of the rack and an alert message. The monitoring includes: receiving, from a plurality of sensors, measurements of: an air flow temperature provided to each of the racks; and an air pressure, temperature and relative humidity difference across, and an electrical power consumption of, the air handling unit(s); updating a computer model of the cooling system with the received measurements; and for each rack, if a level or a rate of change of the inlet air temperature is outside of a preset range for the rack, transmitting an alert message to the display module to indicate a cause based on the computer model.

Abstract: A method and apparatus for monitoring a remote location, such as a data centre, and in particular updating a computer model representation of the remote location based on measured temperature readings. The method includes: i) identifying a measurement point in a computer model representation of the remote location; ii) selecting an infrared temperature sensor in the computer model capable of taking a temperature measurement of the measurement point; iii) determining an orientation for the infrared temperature sensor to assume to take the temperature measurement of the measurement point; iv) instructing the infrared temperature sensor at the remote location to orient itself according to the determined orientation and to take a temperature measurement; v) receiving the temperature measurement from the infrared temperature sensor at the remote location; and vi) updating the computer model representation to assign a temperature to the measurement point based on the received temperature measurement.

Abstract: A computerised method for estimating air flow within a ventilated room comprising a plurality of air supply units configured to supply air to a plurality of vents arranged across a floor of the room over an air supply plenum, the method comprising the steps of: i) identifying a vent having a minimum distance to any one of the air supply units; ii) for each of a selected number of the air supply units, calculating a contribution of air flow supplied to the identified vent from a sum of ratios of distances between the identified vent and each of the air supply units; and iii) repeating step ii) for a vent having a next minimum distance to any one of the air supply units until a contribution of air flow for each of the plurality of vents is calculated.

Abstract: An electrical connector is shown for terminating both signal and coaxial cable. To maintain the same interface pattern, the signal pins for the coaxial cable include contact portions with angled connection sections and ground contacts for contacting the shielding braid of a cable are laterally offset. The housing includes channels to arrange the coaxial cables with the signal contact termination portions and with the ground contact termination portions.
