Abstract: A network communications device includes a chassis, a plurality of modules removably inserted into a plurality of slots in the chassis. A coolant is delivered to a first group of the plurality of modules with a first flow control valve in a first cooling loop and the coolant is delivered to a second group of the plurality of modules with a second flow control valve in a second cooling loop. The network communication device further includes a plurality of sensors for monitoring a temperature in the first cooling loop and the second cooling loop and a control system for controlling delivery of the coolant to the first group and the second group, where the control system controls transmitting a signal to one of the first flow control valve and the second flow control valve to modify a flow of the coolant.

Abstract: A power supply system may comprise a plurality of input buses and an output bus. A plurality of multi-input power supplies may be disposed between the plurality of input buses and the output bus. The plurality of multi-input power supplies may be configured to supply a predetermined amount of power to the output bus before and after a failure event. The failure event may comprise at least one of the following: a failure of a one of the plurality of multi-input power supplies and loss of power on one of the plurality of input buses. Each input to the power supply may include an independent power section to support near or full output power in the event of another input power loss. Any input line loss from an independent power bus/grid may provide line redundancy to the power supply and to the power system as an Uninterruptable Power Supply.

Abstract: An apparatus includes a frame and one or more heat generating elements supported by the frame. A plurality of ports are located at the front portion of the frame, and are electrically coupled to the heat generating elements. A faceplate is coupled to the front portion of the frame and includes one or more port openings to allow access to the ports and a plurality of airflow openings. Each of the airflow openings has a bottom edge aligned with the front portion of the frame and a top edge aligned with the top portion of the frame. The top edges of the airflow openings are set back a predetermined distance from the front portion of the frame.
