The Ethernet port defaults to the following out-of-the box settings:
•DHCP (dynamic IP address)
• Address Duplicate Detection: On
IMPORTANT
When a DHCP server fails, the Micro800 controller allocates IP
addresses in the private range 169.254.0.1 to 169.254.255.254. The
Micro800 controller verifies its address is unique on the network
using ARP. When the DHCP server is again able to service requests,
the Micro800 controller updates its address automatically.
