Chassis Lifting Guidelines for QFX5120 Switches

 

Observe the following guidelines for lifting and moving the switch:

  • Before moving the switch to a site, ensure that the site meets the power, environmental, and clearance requirements.

  • Do not attempt to lift the switch by yourself. We recommend using a mechanical lift to install the switch in a rack or cabinet. If you cannot use a lift, you must remove all components from the chassis before lifting and use a minimum of three people to lift the switch chassis.

    Warning

    Because of the switch’s size and weight, we require the use of a mechanical lift to install the switch in a rack or cabinet or to move the switch from one location to another.

    Caution

    The switch chassis has two handles, one on each side of the chassis. Do not lift a fully loaded chassis by the handles; make sure the chassis is empty before you lift it. If two of the people lifting the chassis use the handles to lift it, a third person must lift from the rear of the chassis. The rear of the chassis is heavier than the front of the chassis, so when you lift the chassis by the handles, the chassis tips toward the heavier back end. The person lifting from the back must be aware of this behavior and be braced to prevent any injury and the chassis from tipping over.

  • Before lifting or moving the switch, disconnect all external cables and wires.

  • Do not grasp the switch by the blue panel at the top front of the chassis. Doing so can cause the panel to detach from the switch.

  • If you are lifting the switch, as when lifting any heavy object, ensure that most of the weight is borne by your legs rather than your back. Keep your knees bent and your back relatively straight. Do not twist your body as you lift. Balance the load evenly among the people lifting the switch and be sure that your footing is firm.
