5

diagnostic lights (4)

Use the lights to help you troubleshoot a computer problem based on the diagnostic code. For more information, see "Diagnostic Lights."

6

USB 2.0 connectors (2)

Use the front USB connectors for devices that you connect occasionally, such as flash memory key or cameras, or for bootable USB devices (see "System Setup" for more information on booting to a USB device).

It is recommended that you use the back USB connectors for devices that typically remain connected, such as printers and keyboards.

power light

The power light illuminates and blinks or remains solid to indicate different states:

No light — The computer is turned off.
Steady green — The computer is in a normal operating state.
Blinking green — The computer is in a power-saving state.
Blinking or solid yellow— See "Power Problems."

To exit from a power-saving state, press the power button or use the keyboard or the mouse if it is configured as a wake device in the Windows Device Manager. For more information about sleep states and how to exit from a power-saving state, see "Power Management."

See "Diagnostic Lights" for a description of light codes that can help you troubleshoot problems with your computer.

Use the blue line-in connector to attach a record/playback device such as a cassette player, CD player, or VCR.

On computers with a sound card, use the connector on the card.

3

line-out connector

Use the green line-out connector to attach headphones and most speakers with integrated amplifiers.

On computers with a sound card, use the connector on the card.

4

mouse connector

Plug a standard mouse into the green mouse connector. Turn off the computer and any attached devices before you connect a mouse to the computer. If you have a USB mouse, plug it into a USB connector.

If your computer is running the Microsoft® Windows® XP operating system, the necessary mouse drivers have been installed on your hard drive.

5

USB 2.0 connectors (4)

Use the back USB connectors for devices that typically remain connected, such as printers and keyboards.

It is recommended that you use the front USB connectors for devices that you connect occasionally, such as flash memory key or cameras, or for bootable USB devices.

6

link integrity light

Green — A good connection exists between a 10-Mbps network and the computer.
Orange — A good connection exists between a 100-Mbps network and the computer.
Yellow — A good connection exists between a 1000-Mbps (or 1-Gbps) network and the computer.
Off — The computer is not detecting a physical connection to the network.

7

network adapter connector

To attach your computer to a network or broadband device, connect one end of a network cable to either a network jack or your network or broadband device. Connect the other end of the network cable to the network adapter connector on your computer. A click indicates that the network cable has been securely attached.

NOTE: Do not plug a telephone cable into the network connector.

On computers with a network connector card, use the connector on the card.

It is recommended that you use Category 5 wiring and connectors for your network. If you must use Category 3 wiring, force the network speed to 10 Mbps to ensure reliable operation.

8

network activity light

Flashes a yellow light when the computer is transmitting or receiving network data. A high volume of network traffic may make this light appear to be in a steady "on" state.

9

USB 2.0 connectors (2)

Use the back USB connectors for devices that typically remain connected, such as printers and keyboards.

It is recommended that you use the front USB connectors for devices that you connect occasionally, such as flash memory key or cameras, or for bootable USB devices.

10

keyboard connector

If you have a standard keyboard, plug it into the purple keyboard connector. If you have a USB keyboard, plug it into a USB connector.

11

microphone connector

Use the pink microphone connector to attach a personal computer microphone for voice or musical input into a sound or telephony program.

On computers with a sound card, the microphone connector is on the card.

12, 13

serial connectors

Connect a serial device, such as a handheld device, to the serial port. The default designations are COM1 for serial connector 1 and COM2 for serial connector 2.

For more information, see "System Setup Options."
