Chapter 2. Overview This guide is intended to be used by customers who are installing optional features or replacing Customer Replaceable Units (CRUs). Note: Use only the parts provided by Lenovo®.
v Always handle parts and other computer components carefully. Handle adapters, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry. v Prevent others from touching the parts and other computer components. v Before you replace a new part, touch the static-protective package containing the part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body.
Locating connectors on the rear of your computer Figure 2 shows the location of connectors on the rear of the computer. Figure 2.
6 Connector Description Standard mouse connector Used to attach a mouse, trackball, or other pointing device that uses a standard mouse connector. Parallel connector Used to attach a parallel printer, parallel scanner, or other devices that use a 25-pin parallel connector. Ethernet connector Used to attach an Ethernet cable for a local area network (LAN). Note: To operate the computer within FCC Class B limits, use a Category 5 Ethernet cable.
