Images
Introduction HP Device Manager can read and write images to and from
supported clients. An image file (.img) is a binary file containing all
the data on a thin client’s flash storage. HP Device Manager
manages images through the
Repository Management tool, which
also provides utilities to verify image integrity.
The
Imaging templates for each OS tab provide various means of
reading and writing images depending on whether or not a PXE
Server is being used. A PXE image can be pulled from a device and
pushed to other devices using the
_PXE Imaging template (see
page 147 and page 150, respectively).
Note: Pushing and pulling images uses the PXE functions of HP
Device Manager and some DHCP server setups may conflict with
PXE. Should you experience problems with PXE, see “Configuring
DHCP Servers” on page 30.
The
_Update Image template enables you to update a device using
an image from a specified FTP Repository without using a PXE
Server (see page 157). The
Neoware XPe OS tab also includes a
_Clone XPe Image template (see page 153).

Repository
Management
The Repository Management tool enables you to import image files
into the Repository and transfer image files between FTP Reposito-
ries. It also enables you to sign and verify PXE images. The
Reposi-
tory Management tool is displayed by selecting Tools > Repository
Management
from the Console’s menu bar. Select the relevant
Images option from the Select an element type to display list.
Importing Images
Image files from an external source (i.e. not created from your local
HP Device Management System) can be imported into an FTP
Repository as described in the section “Importing an Element into
the Repository” on page 52.
