    Abstract: A housing for an electronic device includes a panel, where the panel includes a window. A cage includes a plurality of panels and a first end and a second end that opposes the first end. The cage further includes an opening at its first end and an enclosure disposed between the panels of the cage. Connecting structure is disposed at the first end of the cage, where the connecting structure secures the first end of the cage to the panel. The cage is suitably dimensioned to receive and retain a portion of an optical module within the enclosure when the optical module is inserted within the opening at the first end of the cage.

    Abstract: Presented herein are techniques for power fault management that operates without power-source-side switching. A power transmitter is configured to provide power to a current loop, and a power receiver is configured to receive the power from the current loop. The power receiver is configured to, on a periodic basis, disconnect from the current loop to stop pulling power from current loop for a period of time to enable a safety check to be performed by the power transmitter. The power transmitter is configured to monitor current on the current loop, determine whether the current level on the current loop passes the safety check within a predetermined time interval since a determination that the current level was not within a safe range, and control connectivity of the power to the current loop based on whether the safety check has or has not passed within the predetermined time interval.

    IPC: H05K7/20

    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.
