Appendix B
Serial Port Connectivity
Pinout standards exist for both DB9 and DB25 connectors, however, there are not pinout standards for
serial connectivity using RJ45 connectors. Many Console Servers and serially managed servers/ router/
switches/ PSUs have adopted their own unique pinout; so custom connectors and cables may be
required to interconnect your Console Server
.
In an endeavor to create some move to standardization,
Tripp Lite Console Server products all use the same RJ45 pinout convention as adopted by Cisco, SUN
and others.
Serial Port Pinout
The 16/48 RJ45 connectors on the B092-016 Console Server with PowerAlert, and the B096-048/016
Console Server Management Switch have the following pinout:
