HP LaserJet 4345mfp Series - Configuring and Verifying an IP Address

Configuring and verifying an IP address
You can use either of two options to assign and configure TCP/IP addresses on an HP Jetdirect print
server:
■ HP Web Jetadmin
■ Embedded Web server
TCP/IP assignment
The system administrator or primary user is responsible for determining the TCP/IP address for a
specific print server. If you are unsure what the TCP/IP address should be or if you are unfamiliar
with using TCP/IP on a network, go to the HP Web site at
www.hp.com. Click Search in the upper-
left corner of the Web page and search for TCP/IP Overview.
Automatic discovery
The product is equipped with an HP Jetdirect embedded print server. If a BootP or DHCP server is
available during product installation, the print server is automatically assigned an IP address for use
on the network. This occurs because the print server defaults to 192.0.0.192 (Legacy default) or to
159.254.x.x (Auto IP) if the print server cannot obtain an IP address over the network from a BootP
or DHCP server. The default that is assigned depends on the particular network (small/private or
enterprise) by using sensing algorithms.
To determine the new IP address, print a configuration page and check the TCP/IP status and
address.
Dynamic host configuration protocol (DHCP)
When the product is turned on, the HP Jetdirect print server broadcasts DHCP requests. The DHCP
automatically downloads an IP address from a network server. The DHCP servers maintain a fixed
set of IP addresses and only loan an IP address to the print server. Consult your operating system
documentation to set up a DHCP service on your network.
Verifying the TCP/IP configuration
Print a configuration page at the control panel. Check the TCP/IP status and the TCP/IP addresses.
If the information is incorrect, check your hardware connections (cables, hubs, routers, or switches).
Changing an IP address
Use the following procedures if you need to change the product TCP/IP address.
To change an IP address by using HP Web Jetadmin
Open HP Web Jetadmin. Type the TCP/IP address in the Quick Device Search field and click Go.
At the top menu bar, follow this procedure for discovery options.
1 In the drop-down menu, click Devices.
2 In the drop-down menu, click New Devices. Click Go.
