audio output connections to the AMC connector. See the AMC-compliant adapter card's documentation for more information. The OptiPlex GX1 and OptiPlex NX1 systems include a telephony application programming interface (TAPI) that allows the system board audio to interface with a modem to facilitate speakerphone functionality. The TAPI-compliant telephony input is a mono source with a maximum signal level of 2 Vrms. The OptiPlex GX1 systems and OptiPlex NX1 systems provide chassis intrusion detection. If the computer cover is removed, the Chassis Intrusion setting in the System Setup program changes from Not Detected to Detected and the following message is displayed during the boot routine at system start-up: To clear this field and allow future intrusions to be detected, make sure that the computer cover is closed, and then enter the System Setup program during the system's POST, as described in Appendix A, "System Setup Program." Use the left- or right-arrow key to select Reset for the Chassis Intrusion category. This action changes the setting to its default, Not Detected. NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting the chassis intrusion detector. The OptiPlex GX1 systems and OptiPlex NX1 systems are available with or without integrated 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-T 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: 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 system is not detecting a physical connection to the network. 1-6

The OptiPlex GX1 systems and OptiPlex NX1 systems are available with or
without integrated 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-T stan-
dards. 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:
¼
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.)
¼
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.
