Electrostatic Discharge
HP systems and peripherals contain assemblies and components that are sensitive to electrostatic discharge
(ESD). Carefully observe the precautions and recommended procedures in this manual to prevent component
damage from static electricity.
WARNING Connect to ground with a wrist strap. Connection may be made to any grounded
metal assembly in the cabinet. Both you and the electronic devices must be
grounded to avoid static discharges that can cause damage.
Take these precautions:
• Prepare an ESD safe work surface large enough to accommodate the various assemblies handled during
the upgrade. Use a grounding mat and an anti-static wrist strap, such as those included in the ESD Field
Service Kit (A3024-80004).
• The anti-static bag cannot function as a static dissipating mat. Do not use the anti-static bag for any
other purpose than to enclose a product.
• Treat all assemblies, components, and interface connections as static-sensitive.
• When unpacking cards, interfaces, and other accessories that are packaged separately from the system,
keep the accessories in their conductive plastic bags, until they are ready to be installed.
• Avoid working in carpeted areas, and keep body movement to a minimum while installing accessories.
