Rack Mounting

The Ethernet Hub may stand alone, or may be
mounted in a standard 19-inch equip-ment rack.

Rack mounting produces an orderly installation

when you have a number of related network

devices. Use the six supplied screws to fasten the

supplied mounting brackets to either end of the

hub, then fasten the hub into the rack.
