DHCP Requests Enable/Disable

When a default IP address is assigned, you can configure the print server to send, or not send, periodic DHCP requests. DHCP requests are used to retrieve IP configuration settings from a DHCP server on the network. By default, this parameter is enabled, allowing DHCP requests to be transmitted. However, this parameter may be disabled through supported configuration tools such as Telnet, a Web browser, and SNMP management applications.

HP Jetdirect Wireless Print Server. When initially powered on, a factory-default wired/wireless print server that has no connection to a network will likely self-assign a link-local IP address. If a network connection to a DHCP server-based network is made, the IP address will likely be reconfigured because DHCP requests on the print server are enabled by default.

Default IP on Wireless and Wired Print Servers

Wired and wireless print servers may have different default IP configuration results:

●When powered on, a factory-default print server connected to a network through a cable (wired) will systematically use BOOTP, DHCP, and RARP to retrieve its IP settings. Up to two minutes are used. If configuration is not successful, a default IP address will be assigned as described previously.

●For a factory-default wired/wireless print server that is not connected through a cable, only a wireless Ad Hoc connection is initially available. In this case, retrieval of IP settings from a network is limited to about four seconds. During this time, a single BOOTP request is transmitted, and broadcast packets are sensed. Because a response from a BOOTP server on an Ad Hoc network is unlikely, and the number of broadcast packets sensed will be minimal, a default IP configuration using link-local addressing is likely.

However, the IP configuration may change once the wireless print server is connected a DHCP network because the sending of DHCP requests will be enabled by default.

Configuration tools that require a specific default IP address on the print server for initial communication may not work without modification. For the default IP address settings actually configured on the print server, see the Jetdirect configuration page.
