Wouldn't it be easier if I had an adapter that I could carry around instead of switching cables? Or better yet; maybe I could make a bunch of these cables and keep them plugged into what few older switches we have left.
I know there are probably adapters out there already, but I did not want to purchase anything. I figured making one would be easy enough. Especially since I had about a billion console cables in a box from all the Cisco stuff we ordered (better to reuse than hitting the trash can). So I grabbed the parts and headed to my workbench.
Step 1: Parts and Tools Needed
2 Cisco Console Cables
1 RJ45 Network Jack
Scissors, knife, or cable cutters (or all three... the shielding is tough!)
Punch down tool (unless you have an RJ45 that does not require a special tool)
(OPTIONAL) Multimeter to test the pinouts
Step 2: Cut the Second Cisco Cable
We are going to use the section of cable that still has the 9 pin adapter on it. Take the end of that cable and strip the wiring about half inch down.
Step 3: Wire the RJ45 Jack
Some colors might vary on the Cisco cables (I checked the pile we had), but not much. White and gray are the only colors that I noticed changed in my stack of cables. You might want to grab your trusty multimeter and test the cables for your pinout diagram.
See the wiring chart picture for details.
