Serial console cable kit Cisco A920-CONS-KIT-S= — USB Type-A to RJ-45, black/blue

Cisco A920-CONS-KIT-S= is a serial console cable kit that provides a USB Type-A to RJ-45 connection designed for managing network equipment consoles. The cable kit is intended to connect a PC or other USB-equipped terminal to routers, switches and other devices that use an RJ-45 console port for configuration, troubleshooting and maintenance. The product is available in a two-tone finish of black and blue and is optimized for straightforward physical connection between modern computers and legacy console ports.

Advantages

The cable kit simplifies access to device consoles without requiring legacy serial ports on host computers, enabling direct communications over a USB Type-A interface. It allows technicians to perform device configuration and diagnostics using standard terminal software. The combination of USB Type-A and RJ-45 connectors supports broad compatibility with network hardware that uses modular console cabling. The cable's color scheme helps with quick identification in wiring environments while the kit format ensures a compact, ready-to-use solution for field and lab work.

Suitable for

• Initial configuration of routers and switches
• Firmware updates and device recovery via console access
• Network troubleshooting and real-time diagnostics
• Laboratory and training environments where multiple console connections are used
• Field service operations and on-site maintenance tasks

Key specifications

• Connector 1: USB Type-A (male)
• Connector 2: RJ-45 console (male)
• Cable color: black and blue
• Purpose: serial console communications between host and network devices
• Compatible with standard terminal emulation software over virtual serial ports

How to use

Connect the USB Type-A end of the cable to an available USB port on the host computer. Plug the RJ-45 end into the console port of the network device. Launch terminal emulation software on the host (for example, a program that supports COM/virtual COM ports) and select the appropriate serial port. Configure standard serial communication parameters (commonly 9600 baud, 8 data bits, no parity, 1 stop bit, but verify device-specific requirements) and open the connection to begin console access for configuration, monitoring or troubleshooting.

Usage recommendations

Ensure that the host system has the necessary drivers for USB-to-serial operation if the operating system does not provide native support. Verify the console port settings listed in the device documentation before attempting communication. Store the cable kit in a dry, dust-free environment and avoid excessive bending at connector ends to maintain reliable connections.
