Product Description
The HP Compaq Thin Client vc4815 Series are Redflag Linux-based
terminals that connect over a network to a server where all processing
and storage occurs. Because of the nature of the products,
troubleshooting is significantly simpler than on a standard PC and
previous thin clients.
The Graphical User Interface (GUI) is Chinese on all thin clients. If
you are using a foreign language keyboard, you will need to set
localized settings to perform the localization between a server-based
application and the device, but interaction with the unit itself remains in
Chinese.
Network Firmware
PXE (Pre-boot Execution Environment) is supported on all HP
Compaq Thin Client vc4815 Series products.
PXE allows a client to boot from a server on a network prior to
booting the embedded Operating System (OS) from the local Flash
module. As long as the system is connected to AC power, the Network
Interface Controller (NIC) on a PXE-enabled client remains powered
even when the system is turned off. This allows a network
administrator to remotely wake up the unit and perform various
management tasks, including loading the operating system and other
software onto the device from a server over the network.
