Mounting the thin client
HP t620 Thin Client: HP recommends mounting the thin client in the vertical (tower) orientation, with
the HP logo right-side up. Mounting in other orientations may result in decreased performance under
certain conditions; operating the computer with limited power to prevent overheating is one such
condition. When the integrated fiber NIC is installed in the standard chassis and the chassis is
mounted in the horizontal orientation, the maximum ambient temperature for device operation is
reduced to 35°C (95°F).
HP t620 PLUS Thin Client: There is no orientation limitation for PLUS configurations. However,
optimal performance will be obtained in the vertical (tower) orientation.
This thin client incorporates four mounting points on the right side 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.
NOTE: When mounting to a thin client, use the 15 mm screws supplied with the HP Quick Release.
To use the HP Quick Release:
1. Remove four screws from the right side of the computer.
28 Chapter 2 Hardware changes
2. Using four 15 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.
3. 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.
Mounting the thin client 29
4. 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'

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.
CAUTION: For proper function of the HP Quick Release and a secure connection of all
components, both the release lever on one side of the mounting device and the rounded opening on
the other side must face upward.

C Thin client operation
CAUTION: Ensure that the write filter is enabled after committing necessary configurations to the
thin client flash drive. During normal operation of the thin client, the write filter must be enabled. Also
ensure that Page File is not enabled on thin clients with flash memory storage. Failure to follow these
required actions can void the warranty of the flash storage device. In the event of damage to the flash
storage device due to operation with a disabled write filter or enabled Page File, the damage will not
be covered by HP warranty.
For more information about write filter usage, see the operating system guide for your thin client
available at
Routine thin client care
Use the following information to properly care for your thin client:
http://www.hp.com/support/manuals/thinclients.
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 32.
Keep liquids away from the thin client and keyboard.
●
Turn off the thin client and wipe the exterior with a soft, damp cloth as needed. Using cleaning
●
products may discolor or damage the finish.
38 Appendix C Thin client operation
Supported orientations
HP supports the following orientations for the thin client.
CAUTION: You must adhere to HP-supported orientations to be sure that your thin client functions
properly.
NOTE: HP t620 standard (slim) chassis: HP recommends mounting the thin client in the vertical
(tower) orientation, with the HP logo right-side up. Mounting in other orientations may result in
decreased performance under certain conditions; operating the computer with limited power to
prevent overheating is one such condition.
Supported orientations 39
40 Appendix C Thin client operation
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.
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. Thin clients require proper ventilation to maintain operating temperatures.
Non-supported orientation 41
D 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.
●
Always be properly grounded when touching a static-sensitive component or assembly.
●
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 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.
NOTE: For more information about static electricity, contact an HP authorized dealer, reseller, or
service provider.
