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 / Fax 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
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 / Fax 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 DHCP
Server in your network (typically a Unix, Windows
network) the Print / Fax server will automatically obtains its IP
address from DHCP server and register its name with any RFC 1001
and 1002-compliant dynamic name services.
If you do not want your Print / Fax server configured via
DHCP, BOOTP or RARP, you must set the Boot Method to
Static, this will prevent the Print / Fax server from trying to
obtain an IP address from any of these systems. To change
the Boot Method, you can use the front panel or the BRAdmin
application.
