1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
2. Decide where to position the device in the rack.
3. Install the rear installation blades. See Figure 84 on page 305 .
a. With two mounting screws—and cage nuts and washers if your rack requires them—attach one of
the rear installation blades to the left rear of the rack at the point where you want to mount the
device. Tighten the screws.
b. Position the second rear installation blade at the desired position in the right rear of the rack, so
that it is on the same rack level as the left rear installation blade. If the right and left rear installation
blades are not on the same level, the chassis will rest at an angle in the rack instead of resting flat
and level.
c. With two mounting screws—and cage nuts and washers if your rack requires them—attach the
second rear installation blade to the right rear of the rack at the point where you want to mount
the device. Tighten the screws.

4. Prepare the device for mounting.
a. Place the device on a flat, stable surface.
b. Align the mounting brackets along the front or rear of the side panels of the device chassis depending
on how you want to mount the device. For example, if you want to front-mount the device, align
the brackets along the front of the side panel such that the mounting ears are in the front of the
device chassis. See Figure 85 on page 306 .
c. Align the holes in the mounting brackets with holes on the side panels of the device chassis.
d. Insert mounting screws into the aligned holes. Tighten the screws.
5. Mount the device.
