Removing and Installing a Chassis
Step 13 Remove the chassis from the rack.
Warning An empty chassis weighs approximately 125 pounds (56.7 kg). You need two
people to remove the chassis from the equipment rack safely.
a. Using the side handles to support the weight of the chassis, remove the screws
that attach the chassis rack mount flanges to the rack posts.
Warning There is nothing to support the chassis in the rack when you remove the screws
if the optional rack-mount support brackets are not installed.
b. Carefully lift the chassis out of the rack and set it aside.
