Solution  1009425.1 :   Connecting two Sun servers with RJ45 serial ports  


PreviouslyPublishedAs
213025

Description
This document describes how to wire the RJ45<->RJ45 serial cable that is needed to set up a console and/or LOM access between Sun servers that provide RJ45-style serial ports.


Steps to Follow
Many of the newer Sun servers are equipped with a RJ45 serial connector for console and/or LOM functionality. In order to establish a serial connection between two such hosts, an atypical cable(known as a rollover cable) is required.
A suitable RJ45<->RJ45 rollover cable (Xylogics MicroAnnex Cable) is available for purchase, or as a FRU, under Sun part number 530-3139 from Sun Systems Handbook.

To verify the pinouts of the machines in question, consult the Sun System Handbook Communication troubleshooting page

Pinout for the rollover cable:

color	signal	pin	pin	signal
White/Orange	RTS	1	8	CTS
Orange	DTR	2	7	DSR
White/Green	TxD	3	6	RxD
White/Blue	GND	5	5	GND
Green	RxD	6	3	TxD
White/Brown	DSR	7	2	DTR
Brown	CTS	8	1	RTS

Now you can connect e.g. a Sun Fire[TM] V480 to a Netra[TM] V100.
