Serial Port Connectivity

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:
The LOCAL (console/modem) port on the Console Server uses a standard DB9 connector as tabled below:
