Configuring the print server for DHCP configuration
Once a DHCP server is set up (according to the previous section), the factory-default state of the
print server requires no further action for print server configuration.
Changing the BOOTP/DHCP configuration method
Other configuration tools that include IP configuration, such as the embedded web server or
Telnet, allow you to disable BOOTP and/or DHCP auto-configuration. In each of these tools, three
possible settings for the configuration method are provided; each of the settings has the effect of
disabling others, as follows:
● BOOTP
The print server automatically releases any names and IP addresses associated with the
DHCP server and re-initializes the TCP/IP protocol for the print server (unless a BOOTP
configuration is currently in effect). At this point, TCP/IP is unconfigured, and the print server
begins to send—even before power is cycled—BOOTP requests to acquire new IP
configuration information. If no BOOTP reply is received, the IP address remains at the factory
default 192.0.0.192. DHCP is disabled.
After power to the print server is cycled, only BOOTP requests are sent and only BOOTP
replies are processed. Any configuration of IP parameters done manually is ignored.
● DHCP
The print server automatically releases any names and IP addresses associated with the
BOOTP server and re-initializes the TCP/IP protocol for the print server (unless a BOOTP
configuration is currently in effect). At this point, TCP/IP is unconfigured, and the print server
begins to send—even before power is cycled—DHCP requests to acquire new IP
configuration information. If no DHCP reply is received, the IP address remains at the factory
default 192.0.0.192. BOOTP is disabled.
After power to the print server is cycled, only DHCP requests are sent and only DHCP replies
are processed. Any configuration of IP parameters done manually is ignored.
● Manual
BOOTP and DHCP are disabled.
You should proceed to manually set all of the IP configuration parameters, including IP
address, subnet mask, default gateway, and idle timeout. You can use the settings available in
the same tool you are using.
CAUTION If the print server is switched from using an address allocated by a DHCP server to using a manually
assigned address, that manually assigned address should be outside any DHCP range used for
other devices on the network. An alternative is to tell the DHCP server that the print server's address
is fixed so that it will never be allocated to another client.
Returning to factory defaults
You can return the print server to its factory-default state (also called “cold reset”) by using the
factory-default reset procedure. See Resetting the 310x print server to factory defaults (cold
reset).
