Troubleshooting Guide 1–1

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.

Product Description

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.
