What to Do
1. Carefully turn the system chassis upside down.
Enlist the help of another person to accomplish this safely.
Do not lift the chassis using the plastic panels at the front or the side of the
chassis. Place the system onto a solid surface that spaces the unit about 2 inches
(5 cm) off the floor; for example, use a pair of wooden boards. Do not allow any
of the weight to rest on the plastic panels at the front of the chassis.
2. Remove the eight Phillips screws that secure the floor casters assembly to the
underside of the chassis.
3. Remove the casters assembly and set it aside.
Note - There are two foot glide mounting brackets attached to the underside of
the chassis. Do not remove these brackets unless you are converting the chassis to
a rackmount configuration.
