HP ew2500 802.11b/g Print Server manual Default IPv4 behavior, TCP/IP configuration tools

Default IPv4 behavior

When turned on, a factory-default print server connected to a network through a cable (wired), retrieves its IPv4 settings by systematically using BOOTP, DHCP, and RARP. This can take several minutes to complete. If configuration fails, a default IPv4 address is assigned.

Configuration tools that require a specific default IP address on the print server for initial communication might not function without modification. To view the default IP address settings on the print server, use the HP Jetdirect configuration page.

TCP/IP configuration tools

When a network connection is established, you can configure an HP Jetdirect print server with valid TCP/IP parameters for your network, using the following methods:

●Software solutions Use installation, setup, and management software running on supported systems. For more information see HP software solutions summary on page 7.

●BOOTP/TFTP Download the data from a network-based server by using BOOTP and TFTP each time the printer is turned on. For more information, see “Use BOOTP/TFTP (IPv4) on page 21”.

The BOOTP daemon (bootpd) must be running on a BOOTP server that is accessible by the printer.

●DHCP/TFTP Use DHCP and TFTP each time the printer is turned on. These protocols are supported on HP-UX, Solaris, Linux, Windows Server 2003, Server 2008, NetWare, and Mac OS systems. (See your network operating system manuals to verify that your server supports DHCP.) For more information, see Use DHCP (IPv4) on page 36.

NOTE: For more information about Linux and UNIX systems, see the bootpd man page.

On HP-UX systems, a sample DHCP configuration file (dhcptab) might be located in the /etc directory.

Because HP-UX does not currently provide dynamic domain name system (DDNS) services for its DHCP implementations, HP recommends that you set all print server lease durations to infinite. This ensures that print server IP addresses remain static until DDNS is provided.

●RARP Use RARP to answer the print server's RARP request and supply the print server with the IP address. The RARP method allows you to only configure the IP address. For more information, see “Use RARP (IPv4) on page 39”.

●arp and ping commands (Only for print servers configured with Legacy default IP address 192.0.0.192) Use the arp and ping commands from your system. For more information, see “Use the arp and ping commands (IPv4) on page 40”.

●Telnet Set configuration parameters by creating a Telnet connection from your system to the

HP Jetdirect print server, using the default IP address. Once configured, the print server saves the configuration when turned off and then turned on. For more information, see “Use Telnet (IPv4) on page 41”.

●HP Embedded Web Server Use the HP Embedded Web Server on the HP Jetdirect print server to set configuration parameters. For more information, see HP Embedded Web Server (V.40.xx) on page 64.

●Printer control panel (For printers that support HP Jetdirect control panel menus.) Manually enter the configuration data, using the printer control panel keys. Because you can configure a
