Installing the Rubber Feet To install the rubber feet: 1. Remove the feet from their backing. 2. Line up the hole in each foot with a VESA hole on the bottom of the thin client. Press the foot down firmly to secure it to the thin client. NOTE: The feet provide a protective cushion between the thin client and whatever surface it sits on or is mounted to.
2 Mounting the Thin Client HP Quick Release This thin client incorporates four mounting points on the bottom of the unit. These mounting points follow the VESA (Video Electronics Standards Association) standard, which provides industrystandard mounting interfaces for Flat Displays (FDs), such as flat panel monitors, flat displays, and flat TVs. The HP Quick Release connects to the VESA-standard mounting points, allowing you to mount the thin client in a variety of orientations.
To use the HP Quick Release: 1. Using four 10 mm screws included in the mounting device kit, attach one side of the HP Quick Release to the thin client as shown in the following illustration. Figure 2-2 Connecting the HP Quick Release to the thin client 2. Using four screws included in the mounting device kit, attach the other side of the HP Quick Release to the device to which you will mount the thin client. Make sure the release lever points upward.
3. Slide the side of the mounting device attached to the thin client (1) over the other side of the mounting device (2) on the device on which you want to mount the thin client. An audible 'click' indicates a secure connection. Figure 2-4 Connecting the thin client NOTE: When attached, the HP Quick Release automatically locks in position. You only need to slide the lever to one side to remove the thin client.
Supported Mounting Options The following illustrations demonstrate some of the supported and not supported mounting options for the mounting bracket. ● You can mount a thin client between a flat panel monitor and the wall. Figure 2-5 Thin client mounted with flat panel on wall ● You can mount the thin client on the back of a flat panel monitor stand. Figure 2-6 Thin client mounted on back of monitor stand ● You can mount the thin client on a wall.
Figure 2-7 Thin client mounted on wall ● You can mount the thin client under a desk. Figure 2-8 Thin client mounted under desk Non-supported Mounting Option CAUTION: Mounting a thin client in an non-supported manner could result in failure of the HP Quick Release and damage to the thin client and/or other equipment. Do not mount the thin client on a flat panel monitor stand between the panel and the stand.

3 Thin Client Operation Routine Thin Client Care Use the following information to properly care for your thin client: ● Never operate the thin client with the outside panel removed. ● Keep the thin client away from excessive moisture, direct sunlight, and extreme heat and cold. For information about the recommended temperature and humidity ranges for the thin client, see Specifications on page 31. ● Keep liquids away from the thin client and keyboard.
Figure 3-2 Under monitor stand Non-supported Orientation HP does not support the following orientations for the thin client. CAUTION: Non-supported placement of thin clients could result in operation failure and/or damage to the devices. Thin clients require proper ventilation to maintain operating temperature. Do not block the vents. Do not put thin clients in drawers or other sealed enclosures. Do not place a monitor or other object on top of the thin client.

4 Diagnostics and Troubleshooting LEDs Table 4-1 Power and IDE Flash Activity LEDs LED Status Power LED Off When the unit is plugged into the wall socket and the Power LED is off, the unit is powered off. However, the network can trigger a Wake On LAN event in order to perform management functions. Power LED On Displays during boot sequence and while the unit is on.
Power-On Sequence At power-on, the flash boot block code initializes the hardware to a known state, then performs basic power-on diagnostic tests to determine the integrity of the hardware. Initialization performs the following functions: 1. Initializes CPU and memory controller. 2. Initializes and configures all PCI devices. 3. Initializes USB devices to a known state. 4. The unit boots the operating system. Beep Codes uBoot provides some feedback during startup according to the following table.
Troubleshooting Basic Troubleshooting If the thin client is experiencing operating problems or will not power on, review the following items. Table 4-2 Power-On Troubleshooting Issue Procedures The thin client unit is experiencing operating problems. Ensure that the following connectors are securely plugged into the thin client unit: The thin client unit does not power on. The thin client unit powers on and displays a splash screen, but does not connect to the server.
Table 4-2 Power-On Troubleshooting (continued) A newly connected unknown USB peripheral does not respond or USB peripherals connected prior to the newly connected USB peripheral will not complete their device actions. An unknown USB peripheral may be connected and disconnected to a running platform as long as you do not reboot the system. If problems occur, disconnect the unknown USB peripheral and reboot the platform. Video does not display. 1.

5 Restoring the Flash Image Creating a Bootable USB Flash Drive To create a bootable USB flash drive for purposes of reflashing or restoring the software image on the onboard flash, see the HP ThinPro Administrator’s Guide, section HP ThinState Utility > Manage the ThinPro Image > Capture HP ThinPro Image to a Bootable USB Flash Drive. NOTE: During the restore process, the thin client flash drive is reformatted and all data is erased before the system image is copied to it.
6 Bootloader The t5325 does not use a BIOS; instead, the t5325 uses a bootloader named uBoot. uBoot allows you to configure a limited number of parameters. uBoot does not have an F10 setup menu. To configure the following settings, boot the unit to ThinPro. You must be in administrator mode to configure these settings. Navigate to Control Panel > Setup > ThinPro Configuration, and then select the System tab.
