4. To detach the PowerCage itself, the bolts on the outer flange need to be
removed. Carefully lift the PowerCage down, placing the forward face
down. Do not overtorque these bolts when replacing the PowerCage.
5. Refer to appropriate section for component replacement.
6. When replacing the PowerCage, it is important to place the bolts on the
outer flange in loosely. Torque bolts alternately on one flange and then the
opposite flange to ensure even tightening of the module. A suggested
sequence for torquing PowerCage bolts is shown in
Figure 76 .
Note: The PowerCage is shown with switching components, heatsinks and
clamps removed for ease of lifting.

7. Replace interior assembly in the reverse order of removal.
IMPORTANT The PowerCage can be heavy and it is preferred that two people should extract
the PowerCage from the drive to prevent injury or damage to the module.
