SG250-10P Cannot assign Static IP address

[somethinglesspersonal]

I log in, go to IP Configuration --> IPv4 Interface, click the one and only VLAN1 to select it, then press EDIT... When I switch to Static IP Address, the IP Address field never becomes editable. Only Network Mask becomes available. I just updated the firmware to the latest: 2.3.5.63. See attached image. I have tried rebooting, resetting to factory defaults; nothing ever works. I have tried in Firefox, Chrome, and IE. IE does NOT have adblock plus installed. I've also tried disabling adblock plus on Firefox and Chrome for 192.168.21.19, but the same behavior continues.

I am not familiar with this type of switch but maybe it doesn't let you edit the IP because you use it to access the switch and if you change it, you will lose connectivity to the switch.

Try creating a new vlan with the IP subnet you want to use and test again.

Once an interface address is assigned, it can't be changed. If the new address is on a different subnet, you can just add the new one, but it won't let you have two interfaces on the same subnet, so you may need to be connected through a third IP address, delete the first one and add the new one.

It may be easiest to simply download the startup config file for the switch and edit it locally to change the IP address for the interface, upload it to the switch and reboot.
