Lifting Safely

A fully configured Cisco 7010 weighs approximately 70 pounds. 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.
Whenever you lift the chassis or any heavy object, follow these guidelines:

Warning
These handles are not designed to support the weight of the chassis.

Working with Electricity

The CxBus network interface processors are designed to be removed and replaced while the system
is operating without presenting an electrical hazard or damage to the system. However, you must
shut down the system before removing or replacing the RP, SP, or any of the replaceable components
inside the front panel: the arbiter, fan tray, or power supply.
Follow these basic guidelines when working with any electrical equipment:

2-2 Cisco 7010 Hardware Installation and Maintenance
Never attempt to lift an object that might be too heavy for you to lift by yourself.
Always turn all power supplies OFF (O) and unplug all power cords before opening the chassis.
Always unplug the power cord 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.
Do not wear loose clothing, jewelry (including rings and chains), or other items that could get
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.
Whenever possible, avoid lifting the chassis by yourself.
Ensure that your footing is solid, and balance the weight of the object 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.
Lift the chassis from the bottom; grasp the underside of the chassis exterior with both hands.
Always disconnect all external cables before lifting or moving the chassis.
Use two hands when handling the chassis power supply, which weighs 12 pounds.
Never attempt to lift or tilt the chassis with the handles on the interface processor carriers.
Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
Disconnect all power and external cables before installing or removing a chassis.
