If your unit cannot find a DHCP server and you have not manually assigned an IP address to it the unit automatically selects an address from the AutoIP reserved range Then your unit sends out a ARP request to other nodes on the same network to see whether the selected address is being used e Ifthe selected address is not in use then the unit uses it for local subnet communication e Ifanother device is using the selected IP address the unit selects another address from the AutoIP range and reboots itself After reboot the unit sends out another ARP request to see if the selected address is in use and so on AutolP is not intended to replace DHCP The unit will continue to look for a DHCP server on the network If a DHCP server is found the unit will switch to the DHCP server provided address and reboot Note Ifa DHCP server is found but it denies the request for an IP address the unit does not attach to the network but waits and retries AutoIP can be disabled by setting the unit s IP address to 0 0 1 0 This setting enables DHCP but disables AutoIP DSTni XPress DR User Guide 2 5 Getting Started 2 4 Devicelnstaller You can manually assign the IP address using DeviceInstaller software which is found on the product CD If you want to use a serial connection instead of an Ethernet connection to configure the device go to Serial Port Login on page 2 13 2 4 1 Install Devicelnstaller Software 1 Insert the product CD
