HP Compaq t5720/t5725 thin clients are terminals that connect to a
Microsoft server with Citrix MetaFrame software running atop the
server operating system.
HP has partnered with Altiris to manage HP Compaq thin clients.
Altiris Deployment Solution is a leading-edge tool to help with quick
deployment and for on-going management of the thin clients in your
organization. Each HP Compaq thin client is recognized by the Altiris
Deployment Solution as a supported device. As a result, you need not
track license compliancy for each device. For additional information
about the Altiris Deployment Solution tool, refer to the Altiris
Deployment Solution insert that shipped with the thin client and the
Deployment Solution User Guide that is available at:
www.altiris.com/documentation.

HP Quick Release
The HP Compaq t5720/t5725 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.
To use the HP Quick Release with a VESA-configured thin client:
1. Using four 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.

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.
■ Keep electrostatic-sensitive parts in their containers until they
arrive at static-free workstations.
■ Place parts on a grounded surface before removing them from
their containers.
■ Avoid touching pins, leads, or circuitry.
D
■ Always be properly grounded when touching a static-sensitive
component or assembly.
Hardware Reference Guidewww.hp.comD-1
Electrostatic discharge
Grounding methods
There are several methods for grounding. Use one or more of
the following methods when handling or installing
electrostatic-sensitive parts:
■ Use a wrist strap connected by a ground cord to a grounded
Thin Client chassis. Wrist straps are flexible straps with a
minimum of 1 megohm +/- 10 percent resistance in the ground
cords. To provide proper grounding, wear the strap snug against
the skin.
■ Use heelstraps, toestraps, or bootstraps at standing workstations.
Wear the straps on both feet when standing on conductive floors
or dissipating floor mats.
■ Use conductive field service tools.
■ Use a portable field service kit with a folding static-dissipating
work mat.
If you do not have any of the suggested equipment for proper
grounding, contact an HP authorized dealer, reseller, or service
provider.
For more information about static electricity, contact an HP
✎
authorized dealer, reseller, or service provider.

Routine thin client care
Use the following information to properly care for your thin client:
■ Operate the thin client on a sturdy, level surface. Leave a 1-inch
(2.5-cm) clearance around the air vents to permit the required
airflow.
■ Never operate the thin client with the outside panel removed.
■ Never restrict the airflow into the thin client by blocking the vents
or air intake.
■ 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 Appendix A, “Specifications”.
■ Keep liquids away from the thin client and keyboard.
E
Thin client operation
■ Turn off the thin client before you do either of the following:
❏ Wipe the exterior of the thin client with a soft, damp cloth as
needed. Using cleaning products may discolor or damage the
finish.
❏ Occasionally clean the air vents of the thin client. Lint and
other foreign matter can block the vents and limit airflow.

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. If you have upgraded the SODIMM, remove it and replace the
original SODIMM that came with the unit.
5. Pack the system components and external devices in their original
packing boxes or similar packaging with sufficient packing
material to protect them.

Important service repair information
In all cases, remove and safeguard all external options before
returning the thin client to HP for repair or exchange.
In countries that support customer mail-in repair by returning the
same unit to the customer, HP makes every effort to return
the repaired unit with the same internal memory and flash modules
that were sent.
In countries that do not support customer mail-in repair by returning
the same unit to the customer, all internal options should be removed
and safeguarded in addition to the external options. The thin client
should be restored to the original configuration before returning it to
HP for repair.
