Today I needed to create a “Console Patch Cable” or a Rollover cable, in order to access a Solaris server via Avocent Cyclades ACS32. Making the cable was pretty simple.
How to Make a RJ45 Cable has an excellent run down on how to make different patch cables. If you are familiar with making a standard T568A or T568B cable making a rollover cable can be done if:
you arrange wires as per a standard patch lead of either type “A”, or “B” with the jack on one end “rolled over”. ie you turn the jack upside down and then insert the wires. (NOTE: you only ‘flip’ one end, not both!) Commercial rollover cables are usually made from flat cable to avoid confusion. If you cannot find flat cable you should use YELLOW cable when making rollover cables.
