## Summary description

Vertiv Avocent RJ45 to DB9F cross converter networking cable provides a cross-wired connection between an RJ-45 interface and a DB9 female serial port.

## Long description

The Vertiv Avocent RJ45 to DB9F cross converter networking cable is a passive adapter that provides a cross-wired connection between an RJ-45 interface and a DB9 female serial port. Designed for use where equipment exposes console or serial ports in different formats, this adapter enables serial communication and console access from RJ-45 cabling to devices with a 9-pin female RS-232 port. The adapter is supplied with RJ-45 connectors and implements the cross (null-modem) wiring needed to connect host and terminal equipment without additional cabling or configuration.
Advantages
This passive RJ45 to DB9 female cross adapter simplifies connections between RJ-45 console cabling and DB9F serial ports without requiring signal conversion or power. It is compact and plug-and-play, making it suitable for use in rack environments and localized management access. The cross-wired configuration removes the need for an external null-modem or wiring changes when linking devices with mismatched serial connector types.
Suitable for
 Connecting network switches and routers with RJ-45 console ports to devices with DB9 female RS-232 ports
 Accessing serial consoles on servers, console servers and management appliances
 Temporary or permanent connections in data center rack and cabinet environments
Key specifications
 Connection type: RJ-45 (male) to DB9 (female)
 Wiring: Cross-wired (null-modem configuration)
 Function: Passive adapter for RS-232 serial communication and console access
 Use case: Designed for console and serial port interfacing in networking and server equipment
How to use
Plug the RJ-45 end of the adapter into the RJ-45 console cable or network device console port and connect the DB9 female end to the device requiring a 9-pin serial connection. Because the adapter is cross-wired, no additional null-modem adapter is required when connecting typical host-to-terminal serial interfaces. Ensure both devices share compatible serial settings (baud rate, parity, data bits, stop bits) and that cabling is seated securely before initiating console sessions or serial communication.
Usage recommendations
Use this adapter in indoor, controlled environments such as data centers and server rooms. Verify RS-232 signal levels and serial settings on both devices prior to use. For long cable runs or electrically noisy environments, consider shielded cabling and proper grounding to maintain signal integrity.
