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_310107 1  00:80:77:31:01:07 192.189.207.3

and:

BRN_310107:ht=ethernet:ha=008077310107:\

ip=192.189.207.3:

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 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. To change the BOOT METHOD, use the machine’s control panel or the BRAdmin 
Professional utility.

• On smaller networks, the DHCP server may be the Router.
