Installing the Front Door and Air Intake Frame
If you need to install the optional double-hinged door and air intake frame, you must install them af ter
installing the cable management assemblies on the chassis.
Note For the double-hinged door to easily open or close in either direction, make sure that the chassis is level.
If necessary, remove the chassis from the rack and adjust the bottom-support rails so that the chassis is
level. Also, make sure that the cable management assemblies are aligned to the vertical sides of the
chassis and that the cable management hood is level when you install those components.
