DSP85-250 and DSP85-251 Series Mounting

The following diagrams illustrate the methods for mounting the repeater(s) in a typical wall or rack installation.
Brackets are provided for both options.

Rack mounting a repeater requires two brackets mounted to the front corners of each module, Figure F-2.

Figure F-2: Rack Mounting

Wall mounting uses four brackets, one at each corner.

Figure F-3: Wall Mounting

NOTE

Westell digital repeaters must be supported in the rack system with a shelf or slide
rail. Do not rely on the brackets exclusively to support all the weight of the
modules.
