Abstract: Designs for a rackmount chassis having multiple card slots are presented herein. In one example, an apparatus includes a chassis configured to mount into a server rack, including a plurality of peripheral card slots, and a plurality of status lights configured to provide indications of operational status for an associated slot. The chassis further includes switch circuitry, including at least three switch elements, configured to couple the slots, wherein a first portion of ports on each of the switch elements is coupled to corresponding slots, a second portion of the ports on each of the switch elements is coupled to external ports of the chassis, and a third portion of the ports on each of the switch elements is coupled to at least another among the switch elements. The chassis may further include a plurality of external ports on the chassis communicatively coupled to the slots through the switch circuitry.
