Chapter RPS1000-Business Series 380W RPS Unit Installation & Administration 3 Planning Your Rack-Mount Installation WARNING: To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: • This unit should be mounted at the bottom of the rack if it is the only unit in the rack. • When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Consider this information when you plan your equipment rack installation: • Enclosed racks must have adequate ventilation. Make sure that the rack is not congested because each unit generates heat. The intake ports of equipment that is located higher in the rack can draw heat upward from the equipment that is located near the bottom of the rack. An enclosed rack should have louvered sides and a fan to provide cooling air. • When mounting a chassis in an open rack, make sure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack. • Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which you can determine by experimenting with different configurations. • When equipment installed in a rack (particularly in an enclosed rack) fails, try this test: Operate the equipment by itself, if possible. Power off other equipment in the rack and in adjacent racks to allow the unit under test a maximum of cooling air and clean power. • Install the RPS1000 and the external devices to which it will connect in adjacent shelves in a rack. Tools and Equipment Required To rack-mount the RPS1000, you need these tools and equipment: • Number 12 Phillips screwdriver • Number 8 Phillips screwdriver • Screws for attaching the brackets to the RPS1000 and the RPS1000 to the rack • Rack-mount brackets (19-inch or 24-inch) from the accessory kit Chapter 3: Installation 15 Installing the Switch
