Removal and Replacement Procedures 29
2 Removal and Replacement Procedures
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
(http://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.
Server Blade Warnings and Cautions
WARNING! To reduce the risk of shock or injury from high-current electrical energy, do not remove the server
blade access panel while the server blade is installed in the server blade enclosure. Do not remove the server
blade access panel and then install the server blade into the server blade enclosure.
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.
