MX480 Chassis Lifting Guidelines
The weight of a fully configured chassis is about 163.5 lb (74.2 kg). Observe the following
guidelines for lifting and moving the router:
•
Before moving the router, verify that the intended site meets the specified power,
environmental, and clearance requirements.
•
Do not attempt to lift a fully configured router by yourself. Using a mechanical lift to
maneuver the router into a rack is recommended. If a lift cannot be used, a minimum
of two people must lift the router, and you must remove components from the chassis
before lifting.
To lift routing devices and components, use the following lifting guidelines:
•
Up to 39.7 lbs (18 kg) 1 person lift.
•
39.7 lbs (18 kg) to 70.5 lbs (32 kg) 2 or more person lift.
•
70.5 lbs (32 kg) to 121.2 lbs (55 kg) 3 or more person lift.
•
Above 121.2 lbs (55 kg) material handling systems (such as levers, slings, lifts and
so on) must be used. When this is not practical, specially-trained persons or systems
must be used (riggers or movers).
•
Before lifting or moving the router, disconnect all external cables.
•
As when lifting any heavy object, lift most of the weight with your legs rather than your
back. Keep your knees bent and your back relatively straight and avoid twisting your
body as you lift. Balance the load evenly and be sure that your footing is solid.
