Chapter 2 Preparing for Installation
Electrical Safety
• Before you install the system, ensure that your site is properly prepared so you can avoid having to
move the chassis later to accommodate power sources and network connections.
• A fully populated chassis should be moved only with a hydraulic lift or forklift. Do not attempt to
manually lift a populated chassis.
• Two people are required to safely move a depopulated chassis. This should be done by using the
handles on each side of the chassis.
Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed
to support the weight of the unit. Statement 1032
• Never attempt to lift even a depopulated chassis by yourself. Because of the size and weight of the
chassis, use at least two people to safely lift and move it without causing injury or damaging the
equipment.
• To prevent injury, keep your back straight and lift with your legs, not your back.
• 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 back muscles.
• If you have to move a fully populated chassis and you do not have a hydraulic lift or forklift
available, you must first remove the following components from the chassis:
– Fan assembly module
– AC or DC power entry modules (PEMs)
– Cable interface line cards
– Network uplink line cards
In a fully loaded chassis, these components weigh approximately 170 pounds, so removing them
allows the chassis to be safely moved with two people. The components can then be reinserted after
the chassis has been moved and installed. See
Chapter 5, “Maintaining the Cisco uBR10012 Router”
for instructions on removing these components.
Caution When removing and reinstalling these modules, be certain to follow the precautions given in the
“Preventing Electrostatic Discharge Damage” section on page 2-2.
• Always disconnect all external cables before lifting or moving the chassis.In particular, verify that
all power to the chassis has been removed. Do not try to move a chassis that is connected to power
or that is powered on.
Electrical Safety
All system components are hot-swappable. They are designed to be removed and replaced while the
system is operating without presenting an electrical hazard or damage to the system.
