Removing the rack top cover

The top 6U of the rack can be temporarily detached to make it easier to move through doors or into elevators. You can reattach the top 6U to the rack frame to provide the full 42U rack capacity. The rack is approximately 11 inches (28 cm) shorter with the top removed.

1. If the top, left, and right trim panels are installed remove them otherwise remove the front door.
   Note: If the rack is locked, unlock the doors. Unlock the side panels by sliding the security bar to the unlocked position.
2. Remove the rear door.
3. Remove the side panels. For more information, see Removing and replacing side panels.
4. Remove one screw from the right side of the top cover and one screw from the left side of the top cover. Do for both the front and rear of the cover.
5. Locate the front (A) and rear (C) rack braces that were provided in the shipping container. Fasten each rack brace at the top of the front and rear of the rack, just below the top cover.
6. Use the four screws (B) that were removed from the top cover to secure each rack brace to the rack, as shown in Figure 1.
