Network Cable Requirements; Full Set Of I/O Ports - Dell OptiPlex GXa Service Manual

1-6 Dell OptiPlex GXa and OptiPlex NX Systems Service Manual
of the computer. The RJ45 connector and the NIC interface circuitry are
mounted on the system board.
The NIC connector on the computer's back panel has the following indicators:
•
A yellow activity indicator flashes when the system is transmitting or
receiving network data. (A high volume of network traffic may make this
indicator appear to be in a steady "on" state.)
•
A green link integrity indicator lights up when there is a good connection
between the network and the NIC. When the green indicator is off, the sys-
tem is not detecting a physical connection to the network.

Network Cable Requirements

The computer's NIC connector (RJ45) is designed for attaching to an
unshielded twisted pair (UTP) Ethernet cable. The other end of the cable con-
nects to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or
hub, depending on the network configuration.
Chapter 4, "Using Integrated Devices," in the Reference and Installation Guide
provides instructions for connecting the computer to, and configuring it for use
on, an Ethernet network. For OptiPlex NX systems, refer to the online Network
Administrator's Guide.
