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.

N e t w o r k F i r m w a r e

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.
