7. Use the Phillips number 2 screwdriver to attach the front of the mounting rail to the flange and chassis
using three M4 x 8 mm flathead screws. These slightly longer screws are needed to attach the mounting
bracket through the flange to the chassis. Tighten the screws.
8. Use eight of the shorter, M4 x 6 mm, flathead screws to complete the attachment of the mounting rail
to chassis. Tighten the screws using the Phillips number 2 screwdriver.
9. Repeats Step 6 through Step 8 for the right mounting bracket on the opposite side of the switch.
10. Use a mechanical lift or have one person grasp both sides of the switch, lift it, and position it in the
rack so that the front bracket is aligned with the rack holes.
11. Have a second person secure the front of the switch to the rack using eight mounting screws (and cage
nuts and washers if your rack requires them.) Tighten the screws. See Figure 33 on page 119 for an
example of connecting the mounting rails and blades to a QFX5220-128C.
