3 Installing the Switch

Optional Rack-Mounting Equipment

If you plan to rack-mount the switch, 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

The switch 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 rack mounting the switch, 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. (See page D-2.)

•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.

To rack-mount devices:

1.Attach the brackets to the device using the screws provided in the Bracket Mounting Kit.
