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.
Note -
The right side of the casters assembly mounts to the two foot glide
mounting brackets on the underside of the chassis. If you removed these brackets
previously, you must reinstall them now. See "How to Install the Chassis Foot
Glides" on page 176.
2. Align the holes in the floor casters assembly with the corresponding mounting
holes on the underside of the chassis.
Position the casters assembly with the four casters facing up. Align the two large
holes in the assembly with the large holes in the chassis bottom.
