24 CHAPTER 2: INSTALLING THE SWITCH
Choosing a Suitable Site
The Switch is suited for use in an office environment where it can be
mounted in a standard 19-inch equipmen t rack, or free standing.
Alternatively, the Switch can be rack-mounted in a wiring closet or
equipment room. A rack-mounting k it, containing two mounting
brackets and six screws, is supplied with the Switch.

broadband amplifiers

side of the Switch. We recommend that yo u provide a minimum of
25mm (1in.) clearance.

the units are free standing.
