Microsoft Windows Systems; Discontinue Dhcp Configuration; Use Rarp (Ipv4) - HP Jetdirect 640n Administrator's Manual

On HP-UX systems, a sample DHCP configuration file (dhcptab) might be located in the /etc
directory.
If your HP-UX system does not provide DDNS services for its DHCP implementation, HP
recommends that you set all print server lease durations to infinite. This ensures that print server IP
addresses remain static until dynamic domain name services are available.

Microsoft Windows systems

HP Jetdirect print servers support IP configuration from a supported Microsoft Windows DHCP
server. When configured for BOOTP or DHCP operation and turned on, the HP Jetdirect print server
automatically sends a BOOTP or DHCP request for its IP configuration. If properly set up, a Windows
DHCP server responds with the print server's IP configuration data.
NOTE: For specific topics or for additional support, see the information supplied with your DHCP
server software.
To avoid problems resulting from changing IP addresses, HP recommends assigning printers IP
addresses with infinite lease durations or using reserved IP addresses.

Discontinue DHCP configuration

CAUTION:
printer or system printing configurations for clients or servers.
If you do not want your HP Jetdirect print server configured through DHCP, reset it to use a different
method by selecting one of the following:
1. For IPv4 configured print servers, use the printer control panel to set Manual or BOOTP
configuration. Once set, DHCP is not used.
2. Use Telnet to set Manual (status is User Specified) or BOOTP configuration. Once set, DHCP is
not used.
3. Modify the TCP/IP parameters using the HP Embedded Web Server or HP Web Jetadmin.
If you change to BOOTP configuration, the DHCP parameters are released and the TCP/IP protocol
is initialized.
If you change to Manual configuration, the DHCP IP address is released and the specified IP
parameters are used. If you manually provide the IPv4 address, set all of the configuration
parameters, such as subnet mask, default gateway, and idle timeout.
NOTE: If you re-enable a DHCP configuration, the print server acquires its configuration information
from a DHCP server. When you choose DHCP and complete your configuration session (using
Telnet, for example), the TCP/IP protocol for the print server is re-initialized and all current
configuration information is deleted. The print server then attempts to acquire new configuration
information by sending DHCP requests on the network to a DHCP server.
For DHCP configuration using Telnet, see

Use RARP (IPv4)

You can configure the print server to use RARP on UNIX and Linux systems.
NOTE: If you are configuring an HP Jetdirect wireless print server, this section assumes that a
wireless network connection is established.
