12 Component replacement This section provides detailed instructions for replacing customer-replaceable VLS components. If you need to replace a VLS component not listed in this section, contact an authorized reseller to install the part. 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 system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • 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 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. Warnings and cautions Before removing the node access panel, be sure that you understand the following warnings and cautions. HP StorageWorks 129
