CAUTION: If you are installing more than one switch in a rack or cabinet, install the first one at the bottom of the rack. Do not attempt to install a switch manually in an upper position in a rack or cabinet.

1.Ensure that the rack or cabinet is placed in its permanent location and is secured to the building.

2.Position the switch in front of the rack or cabinet, centering it in front of the adjustable mounting brackets. Use a pallet jack if one is available.

3.With one person on each side and one person in the rear, hold the bottom of the chassis and carefully lift it onto the adjustable mounting brackets installed in a four-post rack or onto the power cord tray installed in a two-post rack. See Figure 49 on page 145.

WARNING: To prevent injury, keep your back straight and lift with your legs, not your back. Do not twist your body as you lift. Balance the load evenly and be sure that your footing is firm.
