3-2 Compaq TFT5600 Rackmount Keyboard and Monitor (RKM) Maintenance and Service Guide Electrostatic CAUTION: When the computer is plugged into an AC power source there is always voltage applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage. Precautions To prevent damage to the system, be aware of the precautions you need to follow when setting up the unit or handling parts. 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. To prevent electrostatic damage, observe the following precautions: Avoid any 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. Make sure you are always properly grounded when touching a staticsensitive 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 workstation or computer 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 heel straps, toe straps, or boot straps 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.

Compaq TFT5600 Rackmount Keyboard and Monitor (RKM) Maintenance and Service Guide
Electrostatic
CAUTION:
When the computer is plugged into an AC power source there is always voltage
applied to the system board.
You must disconnect the power cord from the power source
before opening the computer to prevent system board or component damage.
Precautions
To prevent damage to the system, be aware of the precautions you need to
follow when setting up the unit or handling parts.
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.
To prevent electrostatic damage, observe the following precautions:
■
Avoid any 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.
■
Make sure you are always 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 workstation
or computer 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 heel straps, toe straps, or boot straps 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.
