Hello everyone and thanks to all of you for this great thread.
After finding this thread I decided to order a ICX6610 24 port (non-poe) and managed to get one with a Rev. C PSU which was great.
However I am experiencing issues with connecting to my device's serial port.
In summary there is no USB -> RJ45 serial adapter available near me but I managed to get a USB -> Serial DB9 RS232 (male) and a pin-it-yourself adapter from Serial (female) to RJ45 (female) and I have not been able to find a working pin setup.
The USB to Serial adapter looks identical to this
but with a different brand.
The Serial (female) to RJ45 (female) adapter looks like this
but once again is of a different brand.
The only cables I have at home are Cat6 568b straight through.
I have tried multiple pinouts without success.
For software I have been using Putty with just setting to the correct serial interface and attempting to connect.
So the question is now if there is any way to make all of this work.
If so, how do I go about making this work?
Edit: And now the pin removal broke so I have given up on this project and ordered a USB to RJ45 serial Cisco cable online instead.
It appears like they got back in stock over the weekend.
