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.
Rack-Mounting the Chassis
There are three rack-mount kits and one cable management kit available for both the Catalyst 4948E and the
Catalyst 4948E-F switch chassis. 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.
The process for installing the Catalyst 4948E switch in a 19-inch rack is divided into the following
topics:
• Attaching the Rack-Mount Brackets to the Chassis, page 3-6
• Installing the Chassis in the Rack, page 3-7
• Installing the Cable Guide (Optional), page 3-8
