This chapter provides subassembly/module-level removal and replacement procedures for
system components. After completing all necessary removal and replacement procedures,
verify that all components operate properly by running the appropriate diagnostic software:
•
For server blade components, run the Server Diagnostics Utility, available at
www.hp.com
•
For server blade enclosure and power enclosure components, run the infrastructure
diagnostics. Refer to Chapter 3, "Diagnostic Tools," for more information.
Safety Considerations
Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions 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 nonconductive materials such as ordinary plastic assembly
aids and foam packing.
•
Always be properly grounded when touching a static-sensitive component or assembly.
•
Use conductive field service tools.
