ADNet CONSOLE Cable 1.5 m RJ 45 to DB 9 Female serial RS 232 Port AD-UE-111

The ADNet AD-UE-111 is a standard console cable designed primarily for networking professionals who need to manage hardware like switches, routers, and firewalls. It bridges the gap between a modern networking device’s RJ45 console port and a computer’s legacy DB9 serial port.

Key Specifications

• Model: AD-UE-111

• Length: 1.5 Meters (~5 feet)

• Connectors: * Side A: RJ45 (8-pin) Male

  • Side B: DB9 (9-pin) Female

• Interface: RS-232 Serial

Functional Overview

This cable is used for “Out-of-Band Management.” This means it allows you to configure a device even if the network is down or the device has no IP address yet.

• The RJ45 End: Plugs into the “Console” port of networking gear (commonly seen on Cisco, Juniper, HP, or AdNet devices).

• The DB9 End: Connects to the serial (COM) port on a PC.

  • Note: Since most modern laptops lack a DB9 port, you will likely need a USB-to-RS232 adapter to use this cable with a MacBook or modern Windows laptop.

Core Features

• Flat Ribbon Design: The cable is typically flat to prevent tangling and to allow it to be tucked under doors or through rack gaps easily.

• High Compatibility: While branded by ADNet, it follows the standard “Rollover” pinout used by most major networking brands.

• Plug-and-Play: It doesn’t require drivers itself; the communication is handled by terminal emulation software like PuTTY, Tera Term, or SecureCRT.

Common Use Cases

1. Initial Configuration: Setting up a brand-new switch out of the box.

2. Password Recovery: Accessing the bootloader when you’ve been locked out of the web interface.

3. Firmware Updates: Pushing critical system updates directly via the serial interface.
