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 nonconducting 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 fi eld 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.
Replacing the hard disk
1. Identify the disk that has failed as described in “ How do I know a disk has failed? ” on page 157.
