5.When lifting the chassis, we recommend that you follow the safety precautions listed in the “Safety Precautions” on page 68. Using a lift (or at least three installers—one on the left, one on the right, and one in the front of the chassis), slowly lift and slide the

G10 CMTS onto the equipment shelf. Figure 27 on page 98 illustrates the proper manner in which to manually lift the chassis such that the risk of injury is minimized.

Do not use the handles on the rear fan tray to assist with lifting the G10 CMTS. These handles are solely for the purpose of removing the rear fan tray.

6.Continue sliding the chassis all the way into the rack until the flanges of the mounting brackets are flush with the mounting rails of the rack and the mounting holes in the mounting brackets are aligned with the corresponding holes in the mounting rails.

7.Using the #12 screws supplied in the accessory kit (up to six for each mounting bracket), fasten the chassis to the rack by applying 30 in-lb of torque to each of the screws (see Figure 28 on page 99). Do not completely tighten any screw to its torque specification until all 12 screws are inserted.

8.Attach the ground strap to earth ground. Figure 29 on page 100 illustrates a fully populated rack with three G10 CMTS chassis.

Now you can install additional power supplies and modules.
