SmartServer 2.2 User’s Guide 507
Ensure that you have created an RNI entry for the SmartServer with the LONWORKS Interfaces
application that has the correct IP address/hostname, port and MD5 Authentication Key.
The SmartServer gets a duplicate IP address assigned from a DHCP server, and either boots
using its default IP address (i.e. 192.168.1.222), or boots using the duplicate IP address.
If the SmartServer boots using its default IP address when it has obtained an address via DHCP, it is
probably because the DHCP server assigned an address already in use by another computer on the
network. This may happen if the other computer is disconnected from the network long enough for its
DHCP lease to expire, yet continues using that address after reconnecting to the network. Make sure
all other computers on the network using DHCP have valid leases. If the SmartServer detects this
condition, it will boot using its default IP address (typically 192.168.1.222), and will continue
attempting to contact a DHCP server. Once it can contact a DHCP server, the SmartServer will reboot
to obtain a new IP address.
The SmartServer may not initially detect the above condition, in which case it will boot using the
duplicate IP address. At some point the SmartServer may discover that the address is a duplicate, but
will continue using it. Make sure all computers on the network using DHCP have valid leases. Reboot
the SmartServer to obtain another address, if necessary, or use a statically configured address.
