Determining the Switch Location
The switches are suited for use in the office, where it can be free-standing, or
mounted in a standard 19-inch equipment rack. Alternatively, the device can be rack-
mounted in a wiring closet or equipment room. Two mounting brackets are supplied
with the switch.
When deciding where to install the switch, ensure that:
" The switch is accessible and cables can be connected easily.
" Water or moisture cannot enter the case of the unit.
" Air-flow around the unit and through the vents in the side of the case is not
restricted. You should provide a minimum of 25 mm (1-inch) clearance.
" No objects are placed on top of the unit.
" Units are not stacked more than four high if the switch is free-standing.
Configuration Rules The connectors, supported media types, and maximum distances for the switches are
described in Chapter 1.

Installing the Switch
The switch can be mounted in a rack, or placed free-standing on a tabletop.
Rack Mounting Each switch is two rack units high and will fit in most standard 19-inch racks.
Note
The rack mount kits must not be used to suspend the switch from under a table or
desk, or attach it to a wall.
To rack mount the switch, follow these steps:
1. Place the switch the right way up on a hard flat surface, with the front facing
toward you.
2. Locate a mounting bracket over the mounting holes on one side of the unit.
