Step 9

Have one person carefully lift and position the chassis in the equipment rack so that the center

rack-mount bracket ears are in contact with the rack posts.

Note Use a tape measure or level to ensure that the chassis is positioned level in the equipment rack

before you install the mounting screws.

Step 10 Adjust the chassis up or down in the rack until two screw holes in each center rack-mount bracket ear

are aligned with mounting holes in the equipment rack post.

Step 11 While one person holds the chassis in place, secure the chassis to the equipment rack posts with either

the four 10-32 x 3/4-inch or the four 12-24 x 3/4-inch Phillips-head machine screws (two on each side).

The screws are supplied in the accessory kit. (See Figure 7.)

Note If the equipment rack post-mounting holes are not threaded, you need to obtain the proper size

cage-nuts to secure the center rack-mount mounting screws in place.
