Product Description
The Compaq Evo Thin Clients T20 and T30are Windows-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.
The Windows Graphical User Interface (GUI) is English on all
Thin Clients. If you are using a foreign language keyboard, an
ICA or RDP connection will perform the localization between a
server-based application and the device, but all interaction with
the unit itself is in English.
Optional Firmware
PXE (Pre-boot Execution Environment) is supported on both the
Compaq Evo T20 and T30 NTe w/PXE and XPe products.
PXE allows a client to boot from a server on a network prior to
booting the embedded Operating System (OS) or the OS from the
local hard drive. A PXE-enabled client connects its Network
Information Center (NIC) to the Local Area Network (LAN) via a
jumper which keeps the workstation connected to the network
even when the power is off.
Because a network administrator does not have to physically visit
a specific client and manually boot it, the operating system and
other software can be loaded onto the device from a server over
the network.
PXE is a mandatory element of Intel’s Wired for Management
(WfM) specification and must be supported by the client’s BIOS
and its NIC.

Serial Number Location
The serial number is displayed on the bottom of the units.
Connecting USB Equipment
USB mouse devices and keyboards do not require special drivers
and are considered to be plug and play peripherals. Certain USB
devices such as printers and modems, however, may require
special drivers. For information on requirements for special
drivers, refer to the documentation that is included with the USB
device.
If a USB device is not supported directly by Compaq, a script
may be written to use the Rapport Administrative Software for
Compaq Evo Thin Clients to download the device driver to the
client. For information on script writing, refer to documentation
included with Rapport Administrative Software.
