Cisco serial cable pinout rj45

The Cisco console cable is now ready for use. Rollover Cable:. You can identify a roll-over cable by comparing the two modular ends of the cable. Holding the cables side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. If your cable was purchased from Cisco Systems, pin 1 will be white on one connector, and pin 8 will be white on the other.

If your network is live, ensure that you understand the potential impact of any command. The table and the two images here display the difference between the RJ45 and RJ11 pinout. Note : It is possible the colors of the wires vary between versions of the CCC. Always verify the RJ45 pin number prior to cutting. The image here shows the required cable. Note : Review the section Pinout Explanation before you move forward. The RJ11 cable as shown in the section Pinout Explanation is functional; however, with only 3 small wires that hold the clip to the cable it can easily break.

In order to create a cable that is durable, the plastic sheath inside the plastic end before crimping. The image here shows the blue sheath inside the RJ11 clip. Without modification, the flat console cable sheath is too wide to fit inside the RJ11 terminal clip. In order to fix this use a pair of scissors to trim the outside of the blue sheath. The detailed steps in this document describe how to properly trim the cable. Trim the wire sheath, leaving approximately 0. So somewhere in between there I guess is the maximum.

I think your edit shows that you realize why the rollover pinout is necessary, but for the benefit of others:. The two console cables on each end both rollover cables offset each other, so effectively become a straight pin-to-pin connection on both ends.

So the Ethernet cable between the two keystone jacks has to do the rollover to make this work. Another reason an engineer might want this kind of console connection is security. If you're working in a hyper-secure environment, I can see the benefits of disabling any IP transport on the vty lines. Someone would need physical access to the device to access it in any way. If I understand it correctly it is essentially a low cost rollover adapter that you can making.

Since all of our wiring in Data Center are standardized to Straight-Through ONLY no roll-over or cross-over allowed to avoid troubleshooting confusion. We put this Rollover adapter at any device to convert their console pinout to work with our cabling standards.

You could accomplish the desired result by plugging in the Cisco DB9F-RJ45M cable into any standard network drop at the desk, and connect a standard patch cable in the data center from the patch panel to whatever console port is needed.
