I have a Cisco SG300-10 and I want to be able to access the console using serial cable. The SG-300 has a serial DB9 Female for console input and require a null modem cable.
I have try 2 different commercial null modem cable without success. I even build my own null cable using only pin 2,3,5 of the DB9 without success. Using putty, I not receiving any answer from the managed switch
Have you a commercial partnumber for a null modem serial cable 6 feet DB9-F to DB-9F working for the SG300
If not, have you the pinout of the null modem cable.
My Cisco rep said there was no Cisco part for this and told me to get an off-the-shelf cable. I tried three cables with different pinouts but got no result. I don't have the means to build custom cables.
We need a better answer!
Double check this isn't a baud rate issue - When I connected to my SG300 via. console I had to set my baud rate in PuTTY to 115200.
Is the image how you resolved this issue? Null modem adapter to blue console cable to usb serial converter? Along with following the instructions for Putty?
I have a dying SG-300-28P that we do not know the IP too nor most likely the password. I can tell you my heart slumped when I saw the serial in the back and not a RJ45 port.
Thank you for any assistance.
My SG300-10 & SG300-20 work perfectly with:
StarTech.com MXT100FF Straight Through Serial Cable - DB9 F/F, Gray - F/F, 6 feet
Plugable USB to RS-232 DB9 Serial Adapter (Prolific PL2303HX Rev D Chipset) by Plugable Technologies
PuTTY Settings 115200 baud, 8 data bits, 1 stop bit, no parity , no flow control
The secret sauce was a straight-through cable and not a null modem cable.
Edit - I now have this working
Startech ( With Prolific 2303 RA IC) USB to Male DB9 adapter + straight through Comms Cable - Did work
FDTI USB to Female Serial Cable - never worked
