Abstract: A device and method for deactivating a circuit breaker having an actuating lever and forming part of an electronic module. The electronic module is electrically connected to a power source and is inserted within a housing structure. The deactivating device comprises an activation member moveable between at least two positions, namely activated and deactivated positions, and an interface means for providing a mechanical contact between the activation member and the housing structure. Upon initiating removal of the electronic module from the housing structure for electrical disconnection from the power source, the interface means contacts the activation member to displace the activation member from the activated position to the deactivated position. The activation member in turn contacts the actuating lever to deactivate the circuit breaker thereby ensuring electrical deactivation of the electronic module prior to its electrical disconnection from the power source.

Abstract: A shelf unit for use in an electronic equipment rack, comprises an electronic equipment structure for holding electronic equipment. An auxiliary equipment structure, such as a fiber management plate, is provided for holding auxiliary equipment. A fan tray is movable in and out of a corresponding tray support structure forming part of the shelf unit. The tray support structure is configured such that when the associated fan tray is pushed in, the fan tray extends in a plane behind the auxiliary equipment structure, but when pulled out the fan tray drops down to clear the auxiliary equipment structure and provide access to the fan in the tray.

Abstract: A PCB insertion and extraction device includes a latching lever carrying a latch adapted to cooperate with a catch to latch the lever in an insertion position thereof. The latch is received in a hole extending through the lever and has an operating end which can be manually operated from a front side of the lever to pivot the latch relative to the lever. The catch is defined in the PCB assembly. A switch is provided in the catch so as to be triggered by the latch when the same is positively engaged with the catch.
