billing you for the replacement. With a CSR, HP will pay all shipping and part return costs and determine the courier/carrier to be used. Recommended tools When replacing certain components, such as the power button assembly, the following tools may be necessary: • 4-mm flat-blade screwdriver • Phillips screwdriver Warnings and precautions • Electrostatic Discharge Information • Grounding methods • Equipment Symbols • Weight Warning • Rack warnings and precautions • Device warnings and precautions Electrostatic discharge information To prevent damage to the system, be aware of the precautions you need to follow when setting up the system 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 hand contact by transporting products in static-safe containers such as conductive tubes, bags, or boxes. • Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations. • Cover workstations with approved static-dissipating material. Provide a wrist strap connected to the work surface and properly grounded (earthed) tools and equipment. • Keep work area free of nonconducting materials such as ordinary plastic assembly aids and foam packing. • Place parts on a grounded surface before removing them from their containers. • Avoid touching pins, leads, or circuitry. • Make sure that you are properly grounded when touching a static-sensitive component or assembly. • Place hard drives with the Printed Circuit Board (PCB) side down. • Use conductive field service tools. 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% resistance in the ground cords. To provide proper ground, 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. 1510i Modular Smart Array maintenance and service guide 33

Electrostatic discharge information
To prevent damage to the system, be aware of the precautions you need to follow when setting up the
system or handling parts. A discharge of static electricity from a
fi
nger 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 hand contact by transporting products in static-safe containers such as conductive tubes,
bags, or boxes.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
•
Cover workstations with approved static-dissipating material. Provide a wrist strap connected to
the work surface and properly grounded (earthed) tools and equipment.
•
Keep work area free of nonconducting materials such as ordinary plastic assembly aids and
foam packing.
•
Place parts on a grounded surface before removing them from their containers.
•
Avoid touching pins, leads, or circuitry.
•
Make sure that you are properly grounded when touching a static-sensitive component or
assembly.
•
Place hard drives with the Printed Circuit Board (PCB) side down.
•
Use conductive
fi
eld service tools.
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
fl
exible straps with a minimum of 1 megohm ±10% resistance in the ground
cords. To provide proper ground, 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
fl
oors or dissipating
fl
oor mats.
•
Use conductive
fi
eld service tools.
•
Use a portable
fi
eld service kit with a folding static-dissipating work mat.
