Abstract: A scaled-out fabric coupler (SFC) chassis includes a plurality of root fabric cards installed on the one side of the SFC chassis. Each root fabric card has a plurality of electrical connectors. A plurality of line cards is installed on the opposite side of the SFC chassis. Each line card is one of two types of line cards. One of the two types of line cards is a switch-based network line card having network ports for connecting to servers and switches. The other of the two types of line cards is a leaf fabric card having fabric ports for connecting to a fabric port of a network element. Each of the two types of the line cards has electrical connectors that mate with one electrical connector of each root fabric card installed in the chassis.

Abstract: A first conduit is externally attached to one of two opposing sidewalls of electronic equipment and a second conduit is externally attached to the other of the opposing sidewalls. Each conduit has an open end, a closed end, and a side having a vent that is aligned with a vent in the sidewall of the electronic equipment to which that conduit is attached. The first conduit takes air in through its open end, channels the air in a direction substantially orthogonal to the direction of air flowing through the electronic equipment, and directs the air into the electronic equipment through its aligned vents. The second conduit receives air from the electronic equipment through its aligned vents, channels the air in a direction that is substantially orthogonal to the direction of air flowing through the electronic equipment, and exhausts the air through the open end of the second conduit.

Abstract: A visual indication of the location and duration of a measurement gate relative to the signal being measured is provided on a display. In response to a start gate signal measurements are initiated and a predetermined change is effected in the normally displayed visual indication of the signal being measured. In response to a gate close indication, measurements are terminated and the normally displayed visual indication is resumed. The normal and changed visual indications are effected by a display control signal produced by summing the signal to be measured and an event gate signal at a point in the circuit near where the event gate signal is generated.

Abstract: A method of digitally controlling the gate for a timing counter, to open and close the gate based on the occurrence of signal events, rather than on the envelope of the pulse. In a particular embodiment, a digital divider controls the gate, so that, when a pulse burst of RF is encountered, the gate opens on the second signal event. The divider can be programmed to close the gate any number of signal events later. Measurements are taken for an integral number of signal events, while counting time events from a precision clock. A series of measurements can be taken with various integral numbers of signal events for frequency profiling. By incrementing the digital divider from n to n+1 signal events for successive measurements, and subtracting the results, very narrow gates are effectively generated which move through the pulse cycle by cycle for frequency profiling.
