3 TCP/IP Configuration
To operate properly on a TCP/IP network, the HP Jetdirect print server must be configured with valid
TCP/IP network configuration parameters, such as an IP address that is valid for your network. For
general information on TCP/IP networks, see
TCP/IP Overview.
Server-Based and Manual TCP/IP Configuration
When in a factory-default state and initially powered on, the HP Jetdirect print server will
systematically try to obtain its TCP/IP configuration using a server-based method (BOOTP, DHCP,
and RARP, described later in this chapter). Up to two minutes are used. If configuration is not
successful, a default IP address will be assigned.
The print server may also be configured manually. Manual-based tools include Telnet, a Web
browser, the printer control panel, arp and ping commands (when the default IP address is
192.0.0.192), or SNMP-based management software. TCP/IP configuration values assigned
manually will be retained when powered off/on.
The print server can be re-configured to use either server-based or manual configuration of TCP/IP
settings at any time.
To identify the IP address that is configured on the print server at any time, see the HP Jetdirect
configuration page.
Default IP Address
When in a factory-default state (for example, when shipped from the factory or after a cold reset), the
HP Jetdirect print server has no IP address. A default IP address may or may not be assigned
depending on the network environment.
Default IP Address Will Not Be Assigned
A default IP address will not be assigned if a server-based method (such as BOOTP or DHCP) is
successful. And if the print server is powered off/on, the same method will again be used to retrieve
IP configuration settings. If this method now fails to retrieve the IP configuration settings (for
example, the BOOTP or DHCP server is no longer available), a default IP address will not be
assigned. Instead, the print server will continue to send IP configuration requests indefinitely. You
must cold-reset the print server to change this behavior.
In addition, a default IP address will not be assigned if a network cable is not attached to the print
server.
