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.
