Abstract: An enclosure for an input-output (IO) subsystem comprises: a backplane; a plurality of first slots for accepting corresponding IO option modules; a second slot for accepting an IO controller module; a plurality of first connectors corresponding to the plurality of first slots for connecting the corresponding IO option modules to the backplane; a second connector corresponding to the second slot for connecting the IO controller module to the backplane; and wherein the backplane includes communication links for interconnecting the second connector to each of the plurality of first connectors.

Abstract: In one embodiment, a clock generation system comprises a redundant clock source (RCS) device for receiving multiple timing signals and for generating at least one clock from the timing signals for distribution to other circuits, and first and second hot-swappable oscillator (HSO) devices that each comprise a base housing and an oscillator unit for generating a timing signal, the base housing including an interconnect for coupling to the oscillator unit, the interconnect providing a first connection for the timing signal and providing a second connection to enable detection of insertion and removal of the oscillator unit, wherein the RCS device switches between timing signals from the first and second HSO devices in response to oscillator unit removal detected through the interconnect and switches between timing signals in response to timing signal failure.

Abstract: One disclosed system comprises a first channel for routing at least one of a plurality of cables in a first direction; a second channel for routing said at least one cable in a second direction; and a plurality of teeth spaced apart from one another and disposed in one of said first channel and said second channel, said teeth positioned to create spaces in-between said plurality of cables before said at least one cable transitions from said first direction to said second direction.
