Code:
awk -v line4="<switch IP='158.195.2.567' port='5900' user='testc' password='asdfrp' Code='8'>" '
NR == 4 {
             print line4 ; next
            }
            { print $0 }
' infile

Or

Code:
awk -v line4="<switch IP='158.195.2.567' port='5900' user='testc' password='asdfrp' Code='8'>" '
NR == 4 {
