Four Mounting Rails Procedure
To mount the device on four posts in a rack using a four -rail kit:
1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
2. Decide whether the management end of the device or the ports are to be placed at the front of the
rack.
3. Align the holes in the mounting rail with the button fasteners on the side of the device and slide the
holes over the fasteners to click into place. See Figure 66 on page 281 to see the proper alignment.

4. With three mounting screws—and cage nuts and washers if your rack requires them—attach the mounting
rail to the device. Tighten the screws.
5. Repeats steps 3 and 4 on the opposite side of the device. One end of the device now has front facing
mounting holes, the other end none.
6. With two mounting screws—and cage nuts and washers if your rack requires them—attach one of the
rear installation blades to the rear of the rack at the point where you want to mount the device. Tighten
the screws. The blade helps support the rear of the chassis. You install the second rear installation
blade after securing both front mounting brackets. See Figure 101 on page 330 for detail on installing
the rear blade.
7. Grasp both sides of the device, lift it, and position it in the rack so that the blade receptacle at the rear
of the chassis catches and slides onto the installation blade. See Figure 69 on page 282 .
