NOTE: By default, the NJ225 is configured to automatically obtain an IP address
from a DHCP server. If no DHCP server exists, or if the NJ225 cannot obtain an
IP address, it will default back to its previously configured static IP address. If it
had previously been assigned an IP address, it will default to that one. If it did
not, it will default to the static IP address of 192.168.1.252.

WARNING: If you lock an IP address and reserve it for this IntelliJack, make sure
you configure your DHCP server so it won’t distribute that address to other
devices.
