After the case panels are reattached, connect the cables to the back of the computer. Here are some common external cable connections:

NOTE: Plug in the power cable after you have connected all other cables.

When attaching cables, ensure that they are connected to the correct locations on the computer. For example, older systems use the same type of PS/2 connector for the mouse and keyboard cables, but are color-coded to avoid being connected incorrectly. Often, an icon of the connected device, such as a keyboard, mouse, monitor, or USB symbol, is shown on the connector.

CAUTION: When attaching cables, never force a connection.

To install the various external cables, follow these steps:

Step 1. Attach the monitor cable to the video port (see Figure 1). Secure the cable by tightening the screws on the connector.

Step 2. Plug the keyboard cable into the PS/2 keyboard port (see Figure 2).

Step 3. Plug the mouse cable into the PS/2 mouse port (see Figure 3).

Step 4. Plug the USB cable into a USB port (see Figure 4).

Step 5. Plug the network cable into the network port (see Figure 5).

Step 6. Connect the wireless antenna to the antenna connector (see Figure 6).

Step 7. Plug the power cable into the power supply (see Figure 7).

NOTE: Some motherboards do not have PS/2 ports for connecting the keyboard and mouse. Connect a USB keyboard and a USB mouse to this type of motherboard.
