Console Cable Cisco CAB-CONSOLE-RJ45= RJ-45 to DB9F 1.8m Grey

The Cisco RJ-45 to DB9F Console Cable (CAB-CONSOLE-RJ45=) is a 1.8 m (6 ft) management cable designed to connect a computer terminal or PC serial port to the console port of compatible Cisco routers for configuration and troubleshooting. Originally supplied with Cisco 600, 800, 1600 and 1700 Series routers, the cable has a grey flat design to help identify it among other network leads. It supports reliable serial data transmission for initial setup and ongoing device management and is covered by a 90‑day limited warranty.

Advantages

This console cable provides a direct, standard serial connection between a computer and router console port, ensuring straightforward device configuration without additional adapters. The 1.8 m length offers comfortable reach between equipment, and the grey flat cable is easy to route and distinguish from Ethernet cables. The cable uses an RJ-45 connector on one end and a DB9 female connector on the other, matching legacy console ports on many Cisco routers.

Suitable for

• Configuring and managing Cisco 600, 800, 1600 and 1700 Series routers
• Initial setup and troubleshooting of network devices with RJ-45 console ports
• Connecting a PC serial port (DB9) to a router console for firmware updates or settings changes

How to use

Connect the RJ-45 end of the cable to the router's console port and the DB9 female end to the computer's serial port. If the PC lacks a DB9 serial port, use an appropriate USB‑to‑serial adapter. Open a terminal emulator on the computer (for example PuTTY, Tera Term or minicom), set the serial parameters required by the router (commonly 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control) and start the session to access the router's command line for configuration or diagnostics.

Usage recommendations

Store the cable coiled loosely to avoid kinks, keep it separate from mains power cords to reduce interference, and verify serial settings match the router's documentation before attempting a connection.
