■ Printer Control Panel. You can manually enter the configuration data using the printer control panel keys. The control panel method allows you to configure only a limited subset of configuration parameters. Therefore, control panel configuration is recommended only during troubleshooting or for simple installations. If control panel configuration is used, the print server saves the configuration when powered off/on. For more information, see Using the Printer Control Panel. Using BOOTP/TFTP BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) provide a convenient way to automatically configure the HP Jetdirect print server for TCP/IP network operation. When powered on, the Jetdirect print server sends a BOOTP request message onto the network. A properly configured BOOTP server on the network will respond with a message that contains basic network configuration data for the Jetdirect print server. The BOOTP server's response may also identify a file that contains extended configuration data for the print server. The Jetdirect print server downloads this file using TFTP. This TFTP configuration file may be located on the BOOTP server, or a separate TFTP server. BOOTP/TFTP servers are typically UNIX or Linux systems. Windows NT/2000/Server 2003 and NetWare servers can respond to BOOTP requests. Windows NT/2000/Server 2003 servers are configured through Microsoft DHCP services (see Using DHCP). However, Windows NT/2000/Server 2003 systems may require third-party software for TFTP support. For setup of NetWare BOOTP servers, refer to your NetWare documentation. NOTE If the Jetdirect print server and BOOTP/DHCP server are located on different subnets, IP configuration may fail unless the routing device supports "BOOTP Relay" (allows the transfer of BOOTP requests between subnets). NOTE While the print server may be configured from systems that support BOOTP/DHCP services, this printer may not support printing from these systems (such as UNIX or NetWare systems). Why Use BOOTP/TFTP? Using BOOTP/TFTP to download configuration data has the following benefits: ■ Enhanced configuration control of the HP Jetdirect print server. Configuration by other methods, such as a printer control panel, are limited to select parameters. ■ Ease of configuration management. Network configuration parameters for the entire network can be in one location. ■ Ease of HP Jetdirect print server configuration. Complete network configuration can be automatically downloaded each time the print server is powered on. NOTE BOOTP operation is similar to DHCP, but the resulting IP parameters will be the same when powered off/on. In DHCP, IP configuration parameters are leased and may change over time. When in its factory-default state and powered on, the HP Jetdirect print server will attempt to automatically configure itself using several dynamic methods, one of which is BOOTP. 12 Chapter 3 TCP/IP Configuration ENWW

Using BOOTP/TFTP
BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) provide a convenient way to
automatically configure the HP Jetdirect print server for TCP/IP network operation. When powered
on, the Jetdirect print server sends a BOOTP request message onto the network. A properly
configured BOOTP server on the network will respond with a message that contains basic network
configuration data for the Jetdirect print server. The BOOTP server's response may also identify a file
that contains extended configuration data for the print server. The Jetdirect print server downloads
this file using TFTP. This TFTP configuration file may be located on the BOOTP server, or a
separate TFTP server.
BOOTP/TFTP servers are typically UNIX or Linux systems. Windows NT/2000/Server 2003 and
NetWare servers can respond to BOOTP requests. Windows NT/2000/Server 2003 servers are
configured through Microsoft DHCP services (see
Using
DHCP
). However, Windows NT/2000/Server
2003 systems may require third-party software for TFTP support. For setup of NetWare BOOTP
servers, refer to your NetWare documentation.
NOTE
If the Jetdirect print server and BOOTP/DHCP server are located on different
subnets, IP configuration may fail unless the routing device supports “BOOTP Relay” (allows
the transfer of BOOTP requests between subnets).
NOTE
While the print server may be configured from systems that support BOOTP/DHCP
services, this printer may not support printing from these systems (such as UNIX or NetWare
systems).
