  • Patent number: 9491891
    Abstract: An electrical equipment chassis includes a frame open to a first side and an opposite second side and a power board located near a mid-plane of the chassis coupling power supply modules to first networking modules and a second networking module. A first region open to the first side can receive first power supply modules. A second region open to the first side is adjacent to the first region and can receive the first networking modules and the second networking module oriented with a first orientation. A third region open to the second side can receive fan trays with fans and third networking modules. The third networking modules are oriented orthogonal to the first orientation. The power board at least partially separates the first and third regions and only partially separates the second and third regions. The chassis permits air flow from the first side to the second side.

  • Patent number: 5384767
    Abstract: The nodes of a repeater interface controller which repeats data packets received from one segment of a local area network onto the remaining segments of the local area network include loopback circuitry that allow the data packets received from the one segment to be repeated back onto the one segment in addition to the remaining segments of the local area network, thereby allowing the integrity of the one segment to be verified.

  • Patent number: 5299195
    Abstract: A repeater interface controller receives a data packet at one of a plurality of port nodes from an associated segment of a local area network. At least one port node is configurable as either an attachment unit interface or a twisted pair interface. The port nodes determine a priority port node, of more than one port node receives a data packet at substantially the same time, and transmit the data packet from the priority port node to a central node. The central node receives the data packet from the priority node, repeats the data packet, and transmits the repeated data packet to the non-priority port nodes. Each non-priority port node receives the repeated data packet and transmits the repeated data onto its associated segment.

The port nodes determine a priority port node, if more than one port node receives a data packet at substantially the same time, and transmit the data packet from the priority port node to a central node. The central node receives the data packet, repeats the data packet from the priority node, and transmits the repeated data packet to the non-priority port nodes. Each non-priority port node receives the repeated data packet and transmits the repeated data onto its associated segment. Each port node further includes a partitioning port state machine which monitors its associated segment and partitions the segment from the repeater interface controller when the partitioning port state machine detects a collision in a predetermined number of consecutive data packets.
