Console cables — likewise known as Cisco cables, rollover cables and also management cables — space designed for a particular purpose. They connect Cisco networking devices to terminals or pcs for configuration. Typically, the Cisco end will attach via RJ45, and the terminal end will break up in a serial connection.

What problem most about console cables is the particular nature of the connection. This is not an Ethernet or networking connection. The is a terminal connection, and also its objective is to permit the associated computer to configure the networking device. This is true because that older Cisco equipment and brand-new devices. Construction is performed with the serial connection.

What are the main Kinds of Console Cables?

Console cables come in plenty of shapes and also sizes and with a selection of connector types. There space three that room used much more commonly than the rest, mostly because of the frequency through which girlfriend will view these different connectors.

RJ45 to DB9

A RJ45 come DB9 is more than likely the most well-known console cable today. When upon a time, console cables were linked with improvised “kits” that were little an ext than a string of adapters ~ above the finish of a serial cable. Today, you can acquire an RJ45 to DB9 cable that replaces the “kit” through a solitary cord. Together the surname implies, one finish is RJ45 and the other is DB9.

This is the most straight serial link available, and it comes packaged v a wide variety of Cisco devices. The something of a standard, however despite that, that designed to communicate with terminals that have the DB9 port. If you want to affix it come a pc or laptop, you’ll likely need second adapter between the DB9 end and your USB port.

USB A come Mini-B

Another typical console cable, the CAB-CONSOLE-USB, connect the USB top top a terminal come a mini-B port on the Cisco device. You’ll notice the absence of RJ45 connectors. This is a committed cable that services smaller, frequently portable devices. In spite of the link pieces, this is still a "serial" cable that allows terminal communication.

USB come RJ45

The CAB-CONSOLE-USB-RJ45 is maybe the most modern-day console cable. It ditches the less-used DB9 connector and streamlines your communication. That goes seamlessly from the console port on the Cisco machine to a conventional USB port on a PC. That the simplest method to develop a terminal connection with modern-day equipment, and it is no a typical inclusion in Cisco hardware packages. A grasp of these cables can make network regulate substantially faster and easier.
