Chapter 2 Configuration Tools ARP - Address Resolution Protocol ARP (Address Resolution Protocol) is used to assign a temporary IP address to a ethernet interface card so you can access it from the Ethernet network. After establishing a temporary IP address, you must manually store the IP address within the ethernet, otherwise it will be lost once you power down the printer. Since ARP does not update the IP address of the ethernet, the Ethernet 4400 utility will not show the IP address assigned by ARP. Instead, it will show the IP address currently stored in the NIC. IBM 4400 Ethernet Utility Troubleshooting If the IBM 4400 Ethernet Utility cannot find the ethernet, check the following: • Load the utility onto a Windows station on the same subnet as the ethernet. The utility cannot see print servers across routers unless BOOTP broadcast packets can travel from subnet to subnet. • Wait several minutes for the utility to recognize the ethernet or repower the printer. • Install the utility software on the same subnet. If you load the utility on one subnet and your printer is on another, the utility will not browse to the printer. Instead, it will browse to the subnet that you loaded the utility on. • If you have a DHCP, RARP, or BOOTP server running that may be providing the ethernet with an IP address upon bootup, the utility is not needed to assign an IP address to the print server. NOTE: If the ethernet has an IP address, it will no longer send out a BOOTP packet. This means that the utility will not be able to detect the device on the network. 34
