A tray for retaining disks includes first and second longitudinally extending, spaced apart, parallel rods. A plurality of support plates are directly attached to the rods. Each support plate has at least one notch formed therein for receiving a respective support member. A plurality of rails are attached to the support plates. At least three spaced apart wires are provided. Each wire is formed to have a zigzag configuration adapted to receive and support the disk at an outer peripheral edge thereof. One of the wires is disposed to contact the outer periphery of the disk at a position of zero degrees, another one of the wires is disposed to contact the outer periphery of the disk at a position less than 90 degrees, and a further one of the wires is disposed to contact the outer periphery of the disk at a position greater than 270 degrees.

A noise attenuating system for suppressing noise on circuit board transmission lines is provided. A first ferrous member is attached to a first side of the circuit board and a second ferrous member attached to a second side of the circuit board. The second ferrous member is substantially opposed from the first ferrous member, such that conductive transmission lines are contained between the first ferrous member and the second ferrous member. Transmission line interference is absorbed and suppressed by the first ferrous member and the second ferrous member. In a preferred embodiment, substantially all traces which enter and exit the circuit board on a connector pass between the first ferrous member and the second ferrous member. Apertures in the circuit board allow the ferrous members to adjoin forming a ferrous core.

A cover includes a side panel having an opening therethrough. A sliding member is connected to the side panel, and is slidable to an opened position in which the opening is at least partially uncovered, and is slidable to a closed position in which the opening is closed. A mounting is tab connected to the side panel and is arranged to be accessible through the opening only when the sliding member is in the opened position. A front panel is also provided, which can be fastened and locked to the side panel using no visible fasteners.

An electrical cabinet includes at least one modular enclosure connectable to at least one of a further, substantially identical modular enclosure, and a pedestal enclosure. The modular enclosure has a generally parallelepiped shape, with at least one space therein for the placement of components. A cover is positionable over the exterior sides of the enclosure, and includes a modular rear cover section positionable over the rear side of the modular enclosure to essentially hide the rear side of the modular enclosure from view.
