Standard Rollover Cable Color Codes
Rollover cables, often employed in serial communication, play a crucial role in networking environments specifically concerning the management of devices such as routers and switches. The color-coding standard utilized in rollover cables ensures consistency and clarity, facilitating easier maintenance and troubleshooting. The standard wiring scheme follows a designated pinout sequence that is often referred to as “T568B” or similar configurations, depending on the type of cable and its application.
Table of Contents
The most common rollover cable color code uses a sequence where the pinouts are reversed. This means that pin one connects to pin eight, pin two connects to pin seven, and so on, culminating in pin eight connecting back to pin one. This logic creates a consistent ‘mirror’ of wiring when observing the connectors on both ends of the cable. Generally,
the typical color sequence for the standard rollover cable is as follows: pin one is white/blue, pin two is blue, pin three is white/orange, pin four is orange, pin five is white/green, pin six is green, pin seven is white/brown, and pin eight is brown. The prudent choice of colors aids in identifying individual wires and assists technicians in ensuring adherent connections.
It is notable that various standards may exist, depending on the manufacturer or region; however, uniformity is paramount in facilitating seamless interconnectivity.
