ATTENTION: Electrostatic discharge (ESD) can damage static-sensitive
devices or microcircuitry.
• Disconnect all power before you work on the computer as detailed in
Voltage Precautions on page
• Observe proper packaging and grounding techniques to help prevent
damage.
Follow these ESD precautions:
• Transport the computer and replacement parts in static-safe containers,
such as conductive tubes, bags, or boxes.
• Keep electrostatic-sensitive parts in their containers until they arrive at
the designated static-free work area.
• Cover the designated work area with approved static-dissipating
material:
– Use an antistatic wriststrap that is connected to the work surface.
– Use properly grounded tools and equipment.
• Keep the designated work area free of nonconductive materials, such as
plastic assembly aids and foam packing.
• Avoid contact with pins, leads, or circuitry.
• Always hold components with a printed circuit board (PCB) by its
edges and place it with the assembly side down.
IMPORTANT Before you install hardware or perform maintenance procedures that
require access to internal components, we recommend that you first back up
all computer data to avoid loss.
ATTENTION: Make sure to read and understand all installation and
removal procedures before you configure the computer hardware.
Follow these steps before you remove the cover or you replace a hardware
component.
1. Shut down the computer and all peripherals that are connected to it.
2. Disconnect all cables from power outlets to avoid exposure to high
energy levels.
If necessary, label each cable to expedite reassembly.
3. Disconnect telecommunication cables to avoid exposure to a shock
hazard from ring voltages.
