Installing a FastIron LS Redundant Power Supply
Installation
An RPS may be placed on a desktop or mounted in a rack.
WARNING: DO NOT place an RPS unit on the floor as the case is not waterproof. It is recommended that either
of the RPS units be installed in a network equipment rack.
Selecting a Site
RPS2-EIF units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the
guidelines below when choosing a location.
• The site should:
• Be at the center of all the devices you want to link and near a power outlet.
• Maintain temperatures within 0 to 50 °C (32 to 121 °F) and humidity levels within 5% to 95%, non-
condensing
• Provide adequate space (approximately two inches) on all sides for proper air flow
• Be accessible for installing, cabling and maintaining the devices
• Allow the status LEDs to be clearly visible
• Allow for twisted-pair cable to be always routed away from power lines, fluorescent lighting fixtures and other
sources of electrical interference, such as radios and transmitters.
• Provide a separate grounded power outlet that provides 100 to 240 VAC, 50-60 Hz, is within 2.44 m (8 feet) of
each device and is powered from an independent circuit breaker. As with any equipment, a filter or surge
suppressor is recommended.
Equipment Checklist
After unpacking the FastIron RPS2-EIF, check the contents to be sure you have received all the components. (See
“Package Contents” on page 3-8.) Then, before beginning the installation, be sure you have all other necessary
installation equipment.
Optional Rack-Mounting Equipment
If you plan to rack-mount the RPS, be sure to have the following equipment available:
• Four mounting screws for each device you plan to install in a rack—these are not included
• A screwdriver (Phillips or flathead, depending on the type of screws used)
Mounting
FastIron RPS units can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting
instructions for each type of site follow.
Rack Mounting
Before mounting the unit in a rack, pay particular attention to the following factors:
• Temperature: Since the temperature within a rack assembly may be higher than the ambient room
temperature, check that the rack-environment temperature is within the specified operating temperature
range.
• Mechanical loading: Do not place any equipment on top of a rack-mounted unit.
• Circuit overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
• Grounding: Rack-mounted equipment should be properly grounded. Particular attention should be given to
supply connections other than direct connections to the mains.
