NIC: Dell™ OptiPlex™ E1 Systems
The OptiPlex E1 system has an onboard Ethernet NIC subsystem.
The integrated 10/100-Mbps 3Com® PCI 3C905B-TX Ethernet NIC subsystem supports the Wakeup On LAN feature and the 10BASE-T and 100BASE-TX
standards. The NIC subsystem connects to the Ethernet network through a single RJ45 connector on the back 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:
l A yellow activity indicator that 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.)
l A green link integrity indicator that lights up when there is a good connection between the network and the NIC. When the green indicator is off, the system is
not detecting a physical connection to the network.
See Chapter 4, "Using Integrated Devices," in the Reference and Installation Guide for information on configuring the NIC.
