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.
l If 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.
l If 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.
