I have cisco SG300-28P series managed switch. I'd like to change default ip which is (192.168.1.254). When I am trying to connect the switch using ethernet cable it is shown me there is no access, even I have put static ip to my laptop in the same default subnet ip.

My question is: Is there a way to connect the switch without doing reset? additional thing, I am seeing console serial port at the back of switch. It is first time to see that console which is looks like serial cable.

Thanks.

Using a serial cable, connect that console port to the serial port on your computer (or a USB adapter), load up a terminal program, set it to 19,200115,200 Baud (thx jonathanjo), 8N1 and hit . Other devices use e.g. 19,200 or 38,400 Bd by default.

    Just a comment about baud rate: manual says "115200 bits per second (with release 1.2.5 of the firmware, autobaud detection is enabled by default, so the switch should detect the speed after you press Enter)." cisco.com/c/dam/en/us/td/docs/switches/lan/csbms/sf30x_sg30x/…
