Abstract: There is provided a system for connecting signals between at least two electronic modules. The interconnection conduits are provided via one or more blades, which are equipped with connection areas along their edge toward the modules. This structure opens up more room for high frequency signaling connections. The blades used for the interconnect can be replaced in a live system during operational conditions.

Abstract: In a computer comprising a plurality of plug-in cards and peripheral plug-in cards interconnected through a bus, plug-in places of the bus are designed as system plug-in places and peripheral plug-in places. A clock line is routed along respective clock jack contacts at the plug-in places and comprises an associated clock plug-in contact on a plug-in card. A universal plug-in card (14) comprises a control plug-in contact (24) which is capable of being connected with a control plug-in jack (22) of the bus (12) and activates a clock output signal of the plug-in card (14) which may be supplied to the bus (12) via the clock plug-in contact (C_LK0). The card (14) is capable of working in a peripheral mode in which a clock plug-in contact (C_LK0) acts as a clock input.

Abstract: A computer chassis comprises a main chassis housing including a through opening from a front to a rear of the housing. A front cable feed-through assembly is detachably coupled with the main chassis and inserted into the through opening from the front of the housing. The front cable feed-through assembly includes at least one front cable feed-through slot. A rear cable feed-through assembly is detachably coupled with the main chassis and inserted into the through opening from the rear of the housing. The rear cable feed-through assembly includes at least one rear cable feed-through slot. The rear cable feed-through assembly is detachably connected to the front cable feed-through assembly inside the main chassis housing. The housing includes an upper card guide at a top of the through opening and a lower card guide at a bottom of the through opening.

Abstract: In a computer system, which comprises a plurality of system components, typically in the form of circuit card units, and a common power bus for interconnecting the circuit card units, there are provided a main power supply, an auxiliary power supply and control switches on the power-supplying rails for selectively activating and deactivating circuit elements on the system components (in the form of circuit cards) so that as cards are added or removed, the power can be carefully controlled. According to an insertion method of the invention, undesired disruption of power is prevented by proper sequential deactivation and activation of the power lines from the main power supply and the auxiliary power supply, both of which are for providing power to multiple card units simultaneously. A live removal method also prevents undesired power disturbances.
