•BOOTP

BOOTP is an alternative to rarp that has the advantage of allowing configuration of the subnet mask

and gateway. For more information on BOOTP, see Using BOOTP to configure the IP

address on page 159.

• DHCP

Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address

allocation. If you have a DHCP server in your network (typically a UNIX®, Windows® 2000/XP,

Windows Vista™ and Windows Server®2003 network) the print server will automatically obtain its IP

address from a DHCP server and register its name with any RFC 1001 and 1002 compliant dynamic

name services.

Note

If you do not want your print server configured via DHCP, BOOTP or RARP, you must set the

BOOT Method to Static, this will prevent the print server from trying to obtain an IP address from any of

these systems.

IP Address

This field displays the current IP address of the printer. If you have selected a BOOT Method of Static,

enter the IP address that you wish to assign to the printer (check with your network administrator for the

IP address to use). If you have selected a method other than Static, the printer will attempt to determine

its IP address using the DHCP or BOOTP protocols. The default IP address of your printer will probably

be incompatible with the IP address numbering scheme of your network. We recommend that you contact

your network administrator for an IP address for the network the unit will be connected on.

Subnet Mask

This field displays the current subnet mask used by the printer. If you are not using DHCP or BOOTP to

obtain the subnet mask, enter the desired subnet mask. Check with your network administrator for the

subnet mask to use.

Gateway

This field displays the current gateway or router address used by the printer. If you are not using DHCP or

BOOTP to obtain the gateway or router address, enter the address you wish to assign. If you do not have

a gateway or router, leave this field blank. Check with your network administrator if you are unsure.

IP BOOT Tries

This field displays how many times the printer attempts to scan the network to obtain the IP address

through the BOOT Method you have set (see BOOT Method on page 111). The default setting is 3.

APIPA

The setting of On will cause the print server to automatically allocate a Link-Local IP address in the range

(169.254.1.0 - 169.254.254.255) when the print server cannot obtain an IP address through the

BOOT Method you have set (see BOOT Method on page 111). Selecting Off means the IP address

doesn’t change when the print server cannot obtain an IP address through the BOOT Method you have

set. By default, the APIPA protocol is enabled. If you wish to disable the APIPA protocol, see Disabling the

APIPA protocol on page 118.
