Installation Guide
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
1 Pull both latches up and swing the bottom end of the panel away from
the rack.
2 Grasp firmly on each side of the panel.
3 Lift the panel upward until the panel lip clears the top of the rack.
4 Lay the panel in a safe location with the panel’s outer surface facing
upward to help prevent damage to its cosmetic coating.
5 Repeat step 1 through step 4 for the other upper side panel.
Replacing the Upper Side Panels
1 Lift the upper side panel up onto the rack, hooking the panel lip over
the top of the rack (see Figure 1-4).
2 Swing the bottom of the panel downward onto the rack.
3 Press the panel into the rack until both latches lock into place.
