An electrical power supply system includes a freestanding primary electrical unit, a non-freestanding accessory unit, and an accessory unit support system. The primary electrical unit includes a freestanding cabinet containing a primary electrical component. The accessory unit includes a non-freestanding accessory cabinet containing an accessory electrical component. The accessory unit support system is configured to couple the accessory cabinet to the primary cabinet such that the accessory unit is thereby structurally supported by the primary electrical unit. The accessory cabinet can be selectively decoupled from the primary cabinet and alternatively structurally supported using the accessory support system.

An electronic equipment drawer 20 is aligned with an electrical connector in a tunnel in the horizontal and vertical directions with alignment pins and holes. A screw drive 34 and cam 36 mounted on the drawer engages a tunnel wall and controls insertion into the tunnel to provide proper electrical contact and lock the drawer in place in the tunnel. A bus extender card 25 inserted in a connector 26 centrally located on a mother board 21 is supported by surfaces on a bar 28 extending between end walls 24 of the drawer. The end walls 24 include pairs of channels 31 on opposed walls which support feature cards inserted into connectors mounted on the bus extender card 25.

An electronic equipment drawer is aligned with an electrical connector in a tunnel in the horizontal and vertical directions with alignment pins and holes. A screw drive and cam mounted on the drawer engages a surface of an opening in a wall of the tunnel and controls insertion into the tunnel to provide proper electrical contact and lock the drawer in place in the tunnel. Within the drawer a bus extender card inserted in a connector centrally located on a mother board is supported by surfaces on a bar extending between end walls of the drawer. The end walls include pairs of channels on opposed walls which support feature cards inserted into connectors mounted on the bus extender card.
