Note
In order to enable BOOTP, simply 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), 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 refer to 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: (“BRN” below is “BRW” for a wireless network.)
BRN008077310107 1 00:80:77:31:01:07 192.168.1.2
and:
BRN008077310107: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, simply 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 printer is powered on.

DHCP mode
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
®
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 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 LAN menu, BRAdmin applications, Remote Setup or Web Based Management (web browser).
• On smaller networks, the DHCP server may be the router.
