I have this problem with my SG300-28P switch at this moment.
I am trying to connect its serial interface (back) o my Cisco AS2511-RJ access server, together with my other switches/routers.
This works for all pieces of equipment, except for the SG300-28P.
The other switches and cisco routers work via telnet, i can just telnet into my ip address with the port number 2001 for example to get on the switch in the 1st async slot.
For the Cisco SG300-28P, I have a problem though. After connecting (using Putty, Tera Term) nothing happens. It just stays a black window, without any kind of text coming through. Pushing the enter button doesn't make any difference, while that does the trick on the other switches/routers.
What i was thinking is that the problem might be the BAUD rate, as the SG300-28P doesn't work using 9600 (while connected directly), but instead uses 115200.
I tried putting this in the configuration on port 16, but it still doesn't change a thing.
Now I know this switch can be managed via the website, but i would like to be able to log into it via the access server to have CLI access.
Currently I use the serial to RJ-45 interface adapter that came in the same box as the access server, and from there I connect the green rollover cable to it, straight into the async port.
Has any of you had this problem before, and if so, how did you fix it?
