14 Component Replacement This section provides detailed instructions for replacing customer-replaceable VLS components. See Customer Self Repair for details. CAUTION: Always replace components with the same make, size, and type of component. Changing the hardware configuration voids the warranty. Safety Considerations Before performing component replacement procedures, review all the safety information in this guide. Preventing Electrostatic Discharge To prevent damaging 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 static-sensitive devices or micro circuitry. This type of damage may reduce the life expectancy of the device. Proper packaging and grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage: • Avoid hand contact by transporting and storing 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 workstations. • Cover workstations with approved static-dissipating material. Use a wrist strap connected to the work surface and properly grounded (earthed) tools and equipment. • Keep work area free of non-conductive materials, such as ordinary plastic assembly aids and foam packing. • Place parts on a grounded surface before removing them from their containers. • Always be properly grounded when touching a static-sensitive component or assembly. • Avoid touching pins, leads, or circuitry. Grounding Methods to Prevent Electrostatic Damage 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 megaohm ± 10 percent 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. If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part. For more information on static electricity, or assistance with product installation, contact your authorized reseller. 154 Component Replacement

This section provides detailed instructions for replacing customer-replaceable VLS components. See
Customer Self Repair
for details.
CAUTION:
Always replace components with the same make, size, and type of component.
Changing the hardware configuration voids the warranty.
Safety Considerations
Before performing component replacement procedures, review all the safety information in this
guide.
Preventing Electrostatic Discharge
To prevent damaging 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 static-sensitive devices or micro circuitry. This type of damage may reduce the life
expectancy of the device. Proper packaging and grounding techniques are necessary precautions
to prevent damage.
To prevent electrostatic damage:
•
Avoid hand contact by transporting and storing 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 workstations.
•
Cover workstations with approved static-dissipating material. Use a wrist strap connected to
the work surface and properly grounded (earthed) tools and equipment.
•
Keep work area free of non-conductive materials, such as ordinary plastic assembly aids and
foam packing.
•
Place parts on a grounded surface before removing them from their containers.
•
Always be properly grounded when touching a static-sensitive component or assembly.
•
Avoid touching pins, leads, or circuitry.
Grounding Methods to Prevent Electrostatic Damage
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 megaohm ± 10 percent 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.
If you do not have any of the suggested equipment for proper grounding, have an authorized
reseller install the part. For more information on static electricity, or assistance with product
installation, contact your authorized reseller.
