Configure the IP Address Using DHCP
The Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address
allocation. If you have a DHCP server on your network, the print server obtains its IP address from the DHCP server
automatically and registers its name with any RFC 1001- and 1002-compliant dynamic name services.
NOTE: If you do not want your print server configured via DHCP, you must set the Boot Method to Static so that the
print server has a static IP address. This will prevent the print server from trying to obtain an IP address from any of
these systems.
To change the Boot Method, use the machine’s control panel Network menu, or Web Based Management.
Configure the IP Address Using BOOTP
Before you configure the IP address using Bootstrap Protocol (BOOTP), you must set the machine's Boot Method to
BOOTP. To change the Boot Method, use the machine's control panel Network menu.
BOOTP is an alternative to Reverse Address Resolution Protocol (RARP) that has the advantage of allowing
configuration of the subnet mask and gateway. To use BOOTP to configure the IP address, make sure BOOTP is
installed and running on your host computer (it should appear in the /etc/services file on your host as a real
service; type man bootpd or see your system documentation for information). BOOTP is usually started up via the
/etc/inetd.conf file, so you may need to enable it by removing the "#" in front of the bootp entry in that file.
For example, a typical bootp entry in the /etc/inetd.conf file would be:
#bootp dgram udp wait /usr/etc/bootpd bootpd -i
Depending on the system, this entry might be called "bootps" instead of "bootp".
NOTE: To enable BOOTP, use an editor to delete the "#" (if there is no "#," then BOOTP is already enabled). Then edit
the BOOTP configuration file (usually /etc/bootptab ) and enter the name, network type (1 for Ethernet), MAC
Address (Ethernet Address) and the IP address, subnet mask and gateway of the print server. Unfortunately, the
exact format for doing this is not standardized, so you will need to see your system documentation to determine how
to enter this information (many UNIX
®
systems also have template examples in the bootptab file that you can use for
reference). Some examples of typical /etc/bootptab entries include:
DELL310107 1 00:80:77:31:01:07 192.168.1.2
and:
DELL310107:ht=ethernet:ha=008077310107:\ip=192.168.1.2:
Certain BOOTP host software implementations will not respond to BOOTP requests if you have not included a
download filename in the configuration file. If this is the case, create a null file on the host and specify the name of
this file and its path in the configuration file.
As with RARP, the print server will load its IP address from the BOOTP server when the machine is powered on.
Configure the IP Address Using RARP
Before you configure the IP address using Reverse Address Resolution Protocol (RARP), you must set the machine's
Boot Method to RARP. To change the Boot Method, use the machine's control panel, or Web Based Management.
The Dell print server's IP address can be configured using the RARP facility on your host computer. This is done by
editing the /etc/ethers file (if this file does not exist, you can create it) with an entry similar to the following:
00:80:77:31:01:07 DELL008077310107 (or DELL008077310107 for a wireless network)
