Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide
The default designations for these integrated serial ports are COM1 for serial port 1 and COM2 for serial port
2. Port designations are used in software installation procedures to identify the port used by a device—for
example, specifying the port used by a modem when installing communications software.
The system contains a reconfiguration feature to reassign the serial port's designation if you add an
expansion card containing a serial port using this designation.
If you set the system's integrated serial ports to Auto in the
card containing a serial port configured to a specific designation, the computer automatically maps (assigns)
the integrated ports to the appropriate COM setting as necessary.
Before you add a card with a serial port, check the documentation that accompanied your software to make
sure that the software can be mapped to the new COM port designation.
Keyboard Connector
Your system uses a PS/2-style keyboard. The keyboard cable attaches to a 6-pin miniature DIN connector
on the back panel of your computer.
Network Cable Requirements
Your computer's NIC connector (an RJ45 connector located on the back panel) is designed for attaching an
unshielded twisted pair (UTP) Ethernet cable. Press one end of the UTP cable into the NIC connector until
the cable snaps securely into place.
Connect the other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or
hub, depending on your network configuration.
