Insert and tighten the four screws (2). Figure 2-6 Replacing the metal side cover To replace the HP gt7725 Expansion Module: NOTE: 1. This procedure applies only to the HP gt7725 thin client with Expansion Module installed.
To replace the access panel: 1. Place the access panel on the side of the unit, offset about 6.35 mm (1/4 inch) toward the rear of the unit (1). 2. Slide the panel toward the front of the unit until it locks into place (2). 3. Replace the screw that secures the access panel to the chassis (3) or expansion module.
Installing the USB Device Before beginning the replacement process, review General Hardware Installation Sequence on page 11 for procedures you should follow before and after installing or replacing hardware. ▲ Insert the USB device into the USB port in the secure USB compartment. See the following illustration for the location of the ports in the secure USB compartment.
2. To release the battery from its holder, squeeze the metal clamp that extends above one edge of the battery. When the battery pops up, lift it out (1).

B Security Provisions Securing the Thin Client These thin clients are designed to accept a security cable lock. This cable lock prevents unauthorized removal of the thin client, as well as locking the secure compartment. To order this option, visit the HP Web site at http://www.hp.com and search for your specific thin client model. 1. Locate the cable lock slot on the back panel. 2. Insert the cable lock into the slot, and then use the key to lock it.
C Mounting the Thin Client HP Quick Release This thin client incorporates four mounting points on each side of the unit. These mounting points follow the VESA (Video Electronics Standards Association) standard, which provides industry-standard 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. NOTE: Kit.
To use the HP Quick Release with a VESA-configured thin client: 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 C-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 C-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.
● You can mount the thin client on the back of a flat panel monitor stand. Figure C-6 Thin client mounted on back of monitor stand ● You can mount the thin client on a wall.
● You can mount the thin client under a desk. Figure C-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.
D 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 22. ● Keep liquids away from the thin client and keyboard.
● You can lay the thin client horizontally on its rubber feet. Figure D-2 Horizontal orientation ● You can lay the thin client under a monitor stand with at least one inch of clearance.
Non-supported Orientation HP does not support the following orientation for the thin client. CAUTION: Non-supported placement of thin clients could result in operation failure and/or damage to the devices. CAUTION: 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.
E Electrostatic Discharge A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. Preventing Electrostatic Damage To prevent electrostatic damage, observe the following precautions: ● Avoid hand contact by transporting and storing products in static-safe containers.
F Shipping Information Shipping Preparation Follow these suggestions when preparing to ship the thin client: 1. Turn off the thin client and external devices. 2. Disconnect the power cord from the electrical outlet, then from the thin client. 3. Disconnect the system components and external devices from their power sources, then from the thin client. 4.
