Misconfiguration will not prevent serial-port access

How did you try to connect via serial port?

Your configuration change would not be likley to have either changed the static IP address nor would it have enabled DHCP.

If the device is on the network, and the IP is unknown, then do a nmap scan for any devices with port 80 open for the whole subnet. If the device has the wrong subnet or mask, then the Wireshark utility could be used to find it.
