12 Installation Guide

Lay the door in a safe location with the door’s outer surface

facing upward.

Laying the door flat with the outer surface facing upward helps

prevent damage to its cosmetic coating.

Repeat step a through step d for the left back door.

Replacing the Back Doors

To replace the back doors, perform the steps for removal in reverse.

Removing and Replacing the Side Panels

CAUTION: For stand-alone racks, reinstalling the side panels is necessary

before running systems in the rack to ensure proper cooling within the rack.

NOTE: You must remove the lower side panels in order to install the side

stabilizer feet.

NOTE: Although removing the side panels is not mandatory for installing

systems in a rack, having the sides open makes it easier to install slide assemblies

and support rails and to reverse the direction that the front door opens.

Removing the Upper Side Panels

Push both latches up and swing the bottom end of the panel away

from the rack (see Figure 1-4).

Grasp firmly on each side of the panel.

Lift the panel upward until the panel lip clears the top of the rack.

Lay the panel in a safe location with the panel’s outer surface facing

upward to help prevent damage to its cosmetic coating.

Repeat step 1 through step 4 for the other upper side panel.

Replacing the Upper Side Panels

Lift the upper side panel up onto the rack, hooking the panel lip over the

top of the rack (see Figure 1-4).

Swing the bottom of the panel downward onto the rack.

Press the panel into the rack until both latches lock into place.
