The Switch is suited for use in an internal wiring closet, a network room, 
or telecommunications room, where it can be mounted in a standard 
19-inch equipment rack, or free-standing. 

When deciding where to position the Switch, ensure that:

■

Cabling is located away from:

■

sources of electrical noise such as radios, transmitters and 
broadband amplifiers.

The Switch is accessible and cables can be connected easily.

■

Water or moisture cannot enter the case of the Switch.

■
