Removal and replacement procedures
This chapter provides detailed instructions on how to remove and replace component spare parts.
Required tools
You need the following items for some procedures:
• T-10 Torx screwdriver
• T-15 Torx screwdriver
• 5.0 mm hex nut screwdriver
• Phillips No. 1 screwdriver
• Small flat-bladed, nonconductive tool
Safety considerations
Before performing service procedures, review all the safety information.
Electrostatic discharge
Be aware of the precautions you must follow when setting up the system or handling components. 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 system or component.
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. 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 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 an authorized
reseller.
