Enabling Clients to Access Images

TFTP and DHCP Server Configuration

The Image Manager technology relies upon the industry standard PXE and TFTP technologies to
provide the initial connection to the Thin Client endpoint device. Before clients can access and boot from
images on the HP Image Manager server, you must have a DHCP, PXE and TFTP server configured
to serve the HP Primary Bootstrap Loader file mPXELdr.bin to clients. This network boot program can
be found in the Server directory of the HP Image Manager distribution package (default: C:\Program
Files\HP Image Manager\Image_ Manager_5.0\Server). The Image Manager installer includes a
combination PXE server and TFTP server which can provide PXE information in an environment with
existing DHCP services: the DHCP Service will provide IP address and configuration and HP IM PXE
Server will provide the PXE-specific boot information.
The HP IM PXE Server cannot be run on the same machine as a DHCP server because they access
the same resources. The most common usage is to have an external DHCP supplied. If the DHCP
service MUST run on the same server as Image Manager, then you should:
1. Disable the PXEServer in the HP IM PXE Server. This is done by modifying the config file for HP
IM PXE Server so as to disable the PXEServer capabilities.
2. Set the correct tags in the DHCP scope to indicate the location of the TFTP server to the client
See Appendix D of the Image Manager User Guide for more details.

Windows

HP Image Manager provides a PXE/TFTP server called HP PXEServer. The installation and setup of
this tool is described in Appendix D of the User Guide.
Any RFC-compliant TFTP server (also known as TFTPD) can be used, as long as it can serve the
file mPXELdr.bin and the optional associated .ini files. Refer to your TFTP Server documentation for
more details about how to install and configure your TFTP Server.
NOTE: HP Image Manager's PXE Server includes a TFTP Server that can be used to serve the boot-
loader files. Its usage is described in Appendix D of the HP Image Manager User Guide.
The freeware TFTPD32 (http://www.jounin.net/) has been successfully tested with HP Image Manager,
but only for TFTP operations. This freeware program also offers PXE and DHCP services that are not
fully compatible with HP Image Manager and that must not be used in an environment where HP Image
Manager is used.

Linux

The directory where files served by TFTP are stored is usually /tftpboot or /tftproot.
