5.
Move the lift away from the rack.
6.
Ensure the mounting brackets are flush with the front of the rack.
7.
Install a mounting screw into each of the open front-mounting holes aligned with the
rack, starting from the bottom.
8.
Visually inspect the alignment of the device. If the device is installed properly in the
rack, all the mounting screws on one side of the rack are aligned with the mounting
screws on the opposite side, and the device is level.
9.
After ensuring that the device is aligned properly, tighten the screws.
10.
In a four-post rack, hook the rear support anchors around the bottom rear flange of
the mounting shelf so that its holes line up with the grounding lug screw holes at the
bottom left and right corner of the chassis rear.
NOTE: Earlier versions of the four-post rack mounting hardware did not
require the rear support anchors. If your four-post rack mounting hardware
includes spacer bars and two shelves the rear support anchors are not
required.
11.
Secure the rear support anchors with the provided UNC 1/4-20 (right side) screws
and M6 (left side) screws.
