Lifting the Router Safely

The router chassis weighs 76 pounds when empty (no interface processors or power supplies
installed) and 145 pounds with 2 power supplies and 7 interface processors installed. The chassis is
not intended to be moved frequently. Before you install the router, ensure that your site is properly
prepared, so you can avoid having to move the chassis later to accommodate power sources and
network connections.
Two people are required to lift the chassis. Whenever you lift the chassis or any heavy object, follow
these guidelines:

Always unplug all power cords and remove all power supplies before installing or removing a
chassis.
Keep the chassis area clear and dust free during and after installation.
Keep tools and chassis components away from walk areas.

caught in the chassis. Fasten your tie or scarf and sleeves.
Metal objects heat up when connected to power and ground, and can cause serious burns.
Never attempt to lift the chassis by yourself. The size and weight of the chassis require two
people to safely lift and move it without causing injury or damaging the equipment.
Ensure that your footing is solid and balance the weight of the object between your feet.
Lift the object 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. (See
Figure 2-1.)
Grasp the underside of the chassis exterior with both hands.
Never attempt to lift an object that may be too heavy for you to lift safely. Never attempt
Remove all power supplies before lifting the chassis. Each supply weighs 20 pounds.
