Chapter 3 Installing the Switch Rack-Mounting the Chassis Lifting the Chassis Safely Whenever you lift a chassis, follow these guidelines: • Always disconnect all external cables before lifting or moving the chassis. • Ensure that your footing is solid, and balance the weight of the chassis between your feet. • Lift the chassis slowly; never move suddenly or twist your body as you lift. • Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.

Additionally, there is one optional inlet air duct kit that is available only for the Catalyst 4948E-F switch. Table 3-1 lists the kits and describes their contents.
