NOTICE: When you disconnect external devices from the back of the computer, wait 5 seconds after turning off the computer before you disconnect any devices to avoid possible damage to the system board. Parallel Connector This is used to connect printers. Default designation is LPT1. Mouse Connector Turn off the computer and any attached devices before connecting a mouse to the computer. If your computer uses Microsoft Windows 2000 or Windows NT 4.0, Dell installed the necessary mouse drivers on your hard drive. USB Connectors These are used to attach USB-compliant devices such as keyboards, mice, printers, and computer speakers to your computer. Integrated Network Adapter Connector The network adapter, which includes a Remote Wake Up feature, has the following lights: • A yellow activity light flashes 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.) • A dual-colored link integrity light, which is green when there is a good connection between a 10-megabit per second (Mbps) network and the network adapter and orange when there is a good connection between a 100-Mbps network and the network adapter. When the light is off, the computer is not detecting a physical connection to the network. Network Cable Requirements The network adapter connector attaches an unshielded twisted pair (UTP) Ethernet cable to your computer. Press one end of the UTP cable to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending on your network configuration, and press the other end of the UTP cable into the network adapter connector until the cable snaps securely into place Dell recommends the use of Category 5 wiring and connectors for our customers' networks. NOTE: The integrated parallel port is automatically disabled if the computer detects an installed expansion card containing a parallel port configured to the same address as specified in "Additional System Setup Options."

About Your Computer

NOTICE:

When you disconnect external devices from the back of the

computer, wait 5 seconds after turning off the computer before you disconnect

any devices to avoid possible damage to the system board.

Parallel Connector

This is used to connect printers. Default designation is LPT1.

NOTE:

The integrated

parallel port is

automatically disabled if

the computer detects an

installed expansion card

containing a parallel port

configured to the same

address as specified in

Additional System Setup

Options

Mouse Connector

Turn off the computer and any attached devices before connecting a mouse

to the computer. If your computer uses Microsoft Windows

2000 or

Windows NT 4.0, Dell installed the necessary mouse drivers on your hard

drive.

USB Connectors

These are used to attach USB-compliant devices such as keyboards, mice,

printers, and computer speakers to your computer.

Integrated Network Adapter Connector

The network adapter, which includes a Remote Wake Up feature, has the

following lights:

•

A yellow activity light flashes 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.)

•

A dual-colored link integrity light, which is green when there is a good

connection between a 10-megabit per second (Mbps) network and the

network adapter and orange when there is a good connection between

a 100-Mbps network and the network adapter. When the light is off,

the computer is not detecting a physical connection to the network.

Network Cable Requirements

The network adapter connector attaches an unshielded twisted pair (UTP)

Ethernet cable to your computer. Press one end of the UTP cable to an RJ45

jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending

on your network configuration, and press the other end of the UTP cable

into the network adapter connector until the cable snaps securely into place

Dell recommends the use of Category 5 wiring and connectors for our

customers’ networks.
