The PathWay® 7146 Six-Channel RJ48/RJ45 Normal/Bypass Switch supports connection into a network (NORMAL) or disconnection from a network (BYPASS) of an “in-series” type device or terminal. Each switch channel is able to be switched singly or as a group.  The Model 7146 is enclosed in a 2U, full rack size, all metal black chassis designed to provide EMI/RFI shielding and fit in a standard 19” rack.

The switch may be controlled locally by manually operating the front panel pushbuttons, or remotely from the DB9 Serial Remote port located on the rear panel.  The front panel LED display indicates if the switch is in Normal or Bypass Mode. 

Each channel monitors data activity of port “2” and port “3”. The Model 7146 can be set to different modes of operation to respond to data presence and data failure.
