procedures for HP PC Blade Enclosures with reference to HP Blade PCs.
Safety Considerations
Before performing service procedures, review the following safety information.
Electrostatic Discharge
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary to prevent damage. To prevent electrostatic
damage, observe the following precautions:
●
Transport 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. Use a wrist strap connected to the
work surface and properly grounded tools and equipment.
● Keep the work area free of non-conductive materials such as ordinary plastic assembly aids and
foam packing.
●
Always be properly grounded when touching a static-sensitive component or assembly.
● Avoid touching pins, leads, or circuitry.
● Use conductive field service tools.
