When the

Adapter is

Powered-up with

aConfiguration for “Use Bootp Server”

If the processor adapter is powered up without battery backup, and its IP address was previously saved to flash, the adapter will issue three Bootp requests five seconds apart.

λIf a Bootp response is received from the server, the IP address will be assigned but will not be saved to flash. Use the programming software to save the IP address to flash. If a power cycle occurs on the processor adapter, the IP address that is currently saved in flash will be used.

λIf a Bootp response is not received from the server, the processor adapter will use the IP address that is stored in flash. Three ARP broadcasts are made, five seconds apart, to check for duplicate IP addresses. Then, three gratuitous ARP broadcasts are made two seconds apart with the station’s MAC address and IP address.
