•Ensure that cables do not obstruct the airflow through the chassis.
•Consider heat dissipation of all equipment when determining the
Stabilizing the System
The standard rack dimensions (H x W x D) are 84 x 17.75 x 19.25 inches ( 213.4 x 45.1 x 23.5 cm). Follow these guidelines to stabilize the system:
•Install any stabilizers provided with the rack before mounting or servicing the system in the rack.
•Load the rack from the bottom to the top, with the heaviest system at the bottom.
•Do not stack the system on top of any other equipment. If the system falls, it can cause severe bodily injury and damage the equipment.
•If you are using an equipment shelf, ensure that the shelf is constructed to support the weight and dimensions of the chassis.
•Ensure that the weight of the chassis does not make the rack unstable. Stabilize telco racks with ceiling brackets if the rack is populated with heavy equipment.
•Bolt the rack to the floor for stability.
Lifting the System
Follow these guidelines when lifting the system:
•Disconnect all power and external cables before lifting the system.
•Ensure that your footing is solid and the weight of the system is evenly distributed between your feet.
•Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.
•Do not attempt to lift the system with the handles on the power supplies, front panel, or on any of the cards. These handles are not designed to support the weight of the system.
•Depending on the weight of the system, more than one person might be required to lift it.
Figure 1 shows the number of people needed to lift the system by weight.
