Rollover cables, sometimes referred to as Yost cables are most commonly used to connect to a device's console port to make programming changes to the device. Unlike crossover and straight-wired cables, rollover cables are not intended to carry data but instead create an interface with the device.
A rollover cable (also known as a Yost cable, Cisco cable, or a console cable) is a type of null-modem cable that is used to connect a computer terminal to a router's console port. This cable is typically flat (and has a light blue color) to help distinguish it from other types of network cabling.

The most common form of network cable is called “unshielded twisted pair” (UTP). This cable format is used for the Ethernet wiring standards, which are managed by the Institute of Electrical and Electronics Engineers (IEEE). These wiring standards are referred to by the code 802.3. The Ethernet standards are open to anyone to read and they include ...
The conventional name for the connectors on the ends of Ethernet cables is RJ-45. This is not the proper name however, as the RJ-45 is a discontinued format of telephone wire connector. The proper name for these connectors, according to the 802.3 wiring standards is “8P8C“, which stands for “eight positions, eight connectors.” However, don’t make a...
Why does an Ethernet cable have eight wires in it? Does it matter which color goes where in a connector? The answers to these two questions are surprising. First of all, the UTP cable that is always used for Ethernet networks doesn’t need to contain eight wires. However, this is the convention. The blue pair and the brown pair don’t do anything. Th...
The socket that the RJ-45 fits into is soldered onto a network card. Every piece of equipment that can connect to a cabled network has to have a network card, which is also known as a network interface controller, or NIC. There are actually two types of devices that connect to a network: DTEs and DCEs. DTE stands for “data terminal equipment.” This...
The important factor to remember when wiring RJ-45 plugs is the function of each pin. The following list shows the purpose of each connector within the 8P8C plug that fits into the DTE: 1. Pin 1: Transmit positive signal 2. Pin 2: Transmit negative signal 3. Pin 3: Receive positive signal 4. Pin 4: Nothing 5. Pin 5: Nothing 6. Pin 6: Receive negati...
A straight-through cable is often called a wired patch cable or an Ethernet cable. The cable that comes in the box with your router is a straight through cable – it is the most common format for network cables. The straight through cable is configured as described above. It doesn’t matter whether the cable you buy follows EIA-568A or EIA-568B becau...
Printer cables are tricky. If you connect your printer to a switch, then you need a straight through cable. Conventionally, you can’t use a straight through cable to connect your printer to your computer. This is because both your computer and your printer are DTEs. Both will regard pins 1 and 2 as transmission channels and both will listen for inc...
A crossover cable does exactly as its name suggests, it crosses over the wire from pin 1 at one end to pin 3 at the other connector. The wire that is crimped to pin 2 at one end is attached to pin 6 at the other end and the pins 3 and 6 wires go to pins 1 and 2 respectively in the other connector. The crossover cable follows both EIA-568A and EIA-5...
If you want a cable to connect your computer and printer together, you need a crossover cable. If you have several computers and one printer, you need to buy a switch. All of the computers will connect to the switch with a straight through cableand your printer would also connect to the switch with a straight through cable. Remember, two types of d...
Away from the CCNA exams, there is one more complication to take into account when you are buying network cables. If your device implements MDI and MDI-X, you don’t need to worry about crossover cables. MDI is the Medium Dependent Interface standard and it operates inside the socket of a NIC. It can detect which wire transmissions arrive on rather ...
El cable Rollover (también conocido como cable de Yost o cable de consola) es un tipo de cable de módem nulo que se usa a menudo para conectar un terminal de computadora al puerto de la consola del enrutador. Este cable suele ser plano (y tiene un color azul claro) para ayudarlo a distinguirlo de otros tipos de cableado de red.
Un cable de red con cables que se enrollan y se invierten en secuencia en cada extremo se llama cable de rollover. El primer cable conectado al primer pin en un extremo es del mismo color que el cable conectado al último pin en el extremo opuesto. También llamado cable de consola Cisco, es plano y azul claro, y tiene cables de color blanco ...
Llamado también Rollover cable. Este cable se utiliza para conectar desde el puerto de consola (console port) de un router o switch Cisco hacia a una laptop o PC para realizar nuestras configuraciones usando la interfaz de línea de comandos (CLI: Command Line Interface) y también para verificar nuestro dispositivo.
