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 from the HP
website:
www.hp.com
•
For server blade enclosure and power enclosure components, run the infrastructure
diagnostics. Refer to Chapter 3, “Dia gnostic Tools,” for more information.
Safety Considerations
Electrostatic Discharge Information
2
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.
Server Blade Warnings and Cautions

HP CONFIDENTIAL Codename: Reppin Part Number: 316078-005 Last Saved On: 2/23/04 10:31 AM
Removal and Replacement Procedures
WARNING: To reduce the risk of injury from high-current electrical energy, do not
remove the server blade access panel when power is applied through the HP ProLiant
p-Class diagnostic station. Remove all power from the server blade before removing
the access panel.
WARNING: Setting the server blade Power On/Standby button to the standby position
removes power from most areas of the server blade. This process may take
30 seconds, during which time some internal circuitry remains active. To remove power
completely, remove the server blade from the server blade enclosure.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal
system components to cool before touching them.
CAUTION: When performing non-hot-plug operations, you must power down the server
blade and/or the system. However, it may be necessary to leave the server blade powered up
when performing other operations, such as hot-plug installations or troubleshooting.
Rack Warnings and Cautions
WARNING: The power supply enclosure and the server blade enclosure are very
heavy. To reduce the risk of personal injury or damage to the equipment:
• Observe local occupational health and safety requirements and guidelines for
manual material handling.
• Remove hot-plug power supplies and server blades from their enclosures before
installing or removing the enclosures.
• Use caution and get help to lift and stabilize enclosures during installation or
removal, especially when the enclosure is not fastened to the rack.
WARNING: Always use at least two people to lift a power supply enclosure or server
blade enclosure into the rack. If the enclosure is being loaded into the rack above chest
level, a third person MUST assist with aligning the enclosure with the rails while the
other two people support the weight of the enclosure.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure
that:
• The leveling jacks of the rack are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizers are attached to the rack if it is a single rack installation.
