3 Removal and Replacement Procedures This chapter provides information about the subassembly/module-level removal and replacement 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. Symbols on Equipment These symbols may be located on equipment in areas where hazardous conditions may exist. This symbol in conjunction with any of the following symbols indicates the presence of a potential hazard. The potential for injury exists if warnings are not observed. Consult the documentation for specific details. This symbol indicates the presence of hazardous energy circuits or electric shock hazards. Refer all servicing to qualified personnel. WARNING! To reduce the risk of injury from electric shock hazards, do not open this enclosure. Refer all maintenance, upgrades, and servicing to qualified personnel. Safety Considerations 5

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.
Symbols on Equipment
These symbols may be located on equipment in areas where hazardous conditions may exist.
This symbol in conjunction with any of the following symbols indicates the presence of a potential
hazard. The potential for injury exists if warnings are not observed. Consult the documentation for
specific details.
This symbol indicates the presence of hazardous energy circuits or electric shock hazards. Refer all
servicing to qualified personnel.
