An electronic system includes a rack assembly including a first rail and a second rail defining a first width therebetween and a chassis that supports electronic components and is insertable between the first rail and the second rail. The chassis includes a first side and a second side defining a second width therebetween that is less than the first width. The electronic system further includes a power connector coupled to the chassis and movable between a first position and a second position. The power connector and the second side define a third width when the power connector is in the first position. The power connector and the second side define a fourth width when the power connector is in the second position. The third width is greater than the first width and the fourth width is less than the first width.
