CATX: CATX-CONSOLE with a Network Switch

Overview

This is an example of connecting the CATX-Console CAM to a network switch manufactured by HP/Aruba, Cisco and Juniper. Not all switches use a full serial DB9 console connector and use an RJ45 connection instead.

To connect the CATX-Console CAM, you have a couple of options. the first is to use the original network switch DB9 to RJ45 cable and make an intermediary custom cable that swaps over the pins, or the second option is to make a new RJ45 cable.

Option 1

Using the standard RJ45 to DB9 (Female) cable and create an intermediate cable that joins the CATX-Console and standard RJ45 to DB9 cable to cross over the various pins.

Option 2

Make a replacement RJ45 cable that can connect directly to the CATX-Console CAM.
