HP 510x Print Server manual Enabling or Disabling Dhcp

Enabling or Disabling DHCP

If you do not want your HP Jetdirect print server configured via DHCP, you must disable DHCP configuration. There are three methods for enabling or disabling DHCP:

1.You can use Telnet to enable or disable DHCP operation on the HP Jetdirect print server. When you disable a DHCP configuration via Telnet, 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. At this point, the print server is unconfigured and begins to send BOOTP and RARP requests to acquire new (non-DHCP) configuration information.

2.You can modify the TCP/IP parameters via HP Web Jetadmin.

If you manually provide an IP address when disabling DHCP via Telnet, the print server still releases its DHCP-provided IP address but does not send BOOTP and RARP configuration requests.

Instead, it uses the configuration information you have provided.

Therefore, if you provide the IP address you should also manually set all of the configuration parameters, such as subnet mask, default gateway, and idle timeout.

Note	If the DHCP configuration state is changed from
	disabled to enabled, the print server assumes it
	should acquire its configuration information from a
	DHCP server. This means that when the Telnet
	session is completed, 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 via Telnet, refer to “Using Telnet” in this chapter.
