HP StorageWorks D2D Backup System Instructions for Installing Disks in a Replacement (EH923-90902, September 2007)

Installing a replacement HP D2D Backup System4
Electrostatic discharge information
ESD can damage static-sensitive devices or microcircuit. 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 (earthed) tools and equipment.
• Keep work area free of nonconductive materials, such as ordinary plastic assembly aids and
foam packing.
• Make sure that you are always properly grounded (earthed) when touching a static-sensitive
component or assembly.
• Avoid touching pins, leads, or circuitry.
• Always place drives with the Printed Circuit Board (PCB) assembly-side down.
• Use conductive field service tools
WARNING! Hazardous voltages are present inside the HP D2D Backup System. Always
disconnect AC power from the server and other associated assemblies while working inside the unit.
Serious injury may result if this warning is not observed.
WARNING! To reduce the risk of injury from electric shock, disconnect all power cords to
completely remove power from the system.
WARNING! To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching them.
CAUTION: The HP D2D Backup System must always be operated with the system covers on. Proper
cooling is not achieved when the system covers are removed.
