NOTICE: When you disconnect external devices from the back of the
computer, wait 10 to 20 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 connector is
automatically disabled if
the computer detects an
installed expansion card
containing a parallel
connector 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.
NOTE: USB mice will
only wake the computer
from the S1 (standby) and
S3 (suspend to RAM)
states with a click.
Integrated Network Adapter Connector
The network adapter, which includes a Remote Wake Up feature, has the
following lights:
• A yellow network 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 a good
connection exists between a 10-megabit per second (Mbps) network
and the computer, or is orange when a good connection exists between
a 100-Mbps network and the computer. 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.
