Chapter 1 Introduction Overview The Compaq NC7131 Gigabit Server Adapter is a high-performance Ethernet adapter with a fully integrated 10/100/1000 controller that delivers up to 1000 Mb/s Ethernet over twisted-pair (copper) cabling. The Compaq NC7131 adapter has one auto-negotiating RJ-45 port and LED indicators showing link, activity, and port speed. The NC7131 Gigabit Server Adapter is a supported option for selected Compaq ProLiant™ servers.
1-2 Compaq NC7131 Gigabit Server Adapter User Guide Figure 1-1. RJ-45 port and LED locations LED Indicators The following table describes the adapter LED indicators located on the front panel of the Compaq NC7131 Server Adapter. Table 1-1 10/100/1000 LED Operations for the NC7131 Adapter LED LNK ACT 10/100/1000 Display Description On Link to the adapter is established. The adapter is receiving power and the cable connection is secure. Off There is no link to the adapter.
Introduction 1-3 UTP Category 5 Cable The NC7131 Server Adapter can use existing Category 5 (or better) cable to deliver Gigabit Ethernet over copper, according to the IEEE 802.3ab specifications. For new installations, Category 5e cable is recommended. For troubleshooting and other information about cabling, see, “UTP Cable Specifications” in Appendix C.
Chapter 2 Installing the Adapter This chapter describes installation precautions and explains how to install the adapter. It also describes how to connect the network cable. WARNING: To avoid the risk of personal injury or damage to the equipment, consult the safety information and user documentation provided with your equipment before attempting the installation of the adapter. Many servers are capable of producing energy levels that are considered hazardous.
2-2 Compaq NC7131 Gigabit Server Adapter User Guide Installing the Adapter in a Server Refer to the Compaq ProLiant server documentation for additional information on how to safely install a PCI card in your server. Figure 2-1. Installing the adapter in a server 1. If the server is not PCI Hot Plug compliant, power down the server and unplug the power cord. 2. Remove the server cover and the cover bracket from a PCI slot.
Installing the Adapter Connecting the Network Cable Network connections for the NC7131 Server Adapter can employ existing UTP Category 5 (or better) cable for Gigabit over copper transmissions. For new installations, Category 5e (enhanced Category 5) or better cable is recommended. To secure the cable, plug the cable connector into the RJ-45 port. Ensure that the tab on the plug clicks into position indicating that it is properly seated. For more information, see “UTP Cable Specifications” in Appendix C.
Appendix A Regulatory Compliance Notices Federal Communications Commission Notice This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

Appendix B Electrostatic Discharge To prevent damage to the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage, observe the following precautions: Avoid hand contact by transporting and storing products in static-safe containers.
Appendix C Specifications NC7131 Gigabit Server Adapter Specifications Table C-1 NC7131 Gigabit Server Adapter Specifications Specification Description Network Controller Chipset Intel 82543GC MAC Data Transfer Method PCI 32/64 (33/66MHz / Busmaster DMA) Standards Supported IEEE 802.3ab, 802.3u, 802.1Q, 802.1p, 802.1z Dimensions 6.4 x 2.8 inches (L x W), 16.3 cm x 7.
C-2 Compaq NC7131 Gigabit Server Adapter Reference Guide UTP Cable Specifications To connect to the network, the NC7131 adapter uses the following cable for 1000Base-T transmission. Category 5 or better UTP twisted-pair 22-26 AWG, 100Ω @ 1 MHz EIA/TIA 568a or EIA/TIA 568b Using UTP Category 5 Cable in Gigabit Over Copper Installations For Gigabit over copper installations, UTP Category 5 or better 1000Base-T cable must comply with the IEEE 802.3ab 1000Base-T standard.
Specifications C-3 RJ-45 Pinouts and Crossover Function The Ethernet standard also specifies that each segment implement a crossover function to connect the transmitter of one device to the receiver of a device at the other end, and vice-versa. The crossover function may be implemented internally at the hub/switch, or externally, through the twisted-pair media.
C-4 Compaq NC7131 Gigabit Server Adapter Reference Guide 10/100 Crossover Pinouts Unless the crossover function is implemented within the hub/switch, you must implement the crossover through the twisted pair media using the physical pinouts indicated in Table C-3.
Specifications C-5 Gigabit Over Copper Internal Straight-Through Pinouts Unlike some connections in which the crossover function is implemented internally at the hub/switch, the NC7131 adapter provides its own automatic crossover function. This means you can wire twisted-pair media straight-through for adapter-to-hub/switch or adapter-to-adapter connections, using the pinouts shown in Table C-4. NOTE: To operate at Gigabit speeds, all four pairs of wires must be terminated within the RJ-45 connector.
C-6 Compaq NC7131 Gigabit Server Adapter Reference Guide Gigabit Over Copper External Crossover Pinouts When a crossover function is not provided by either the adapter or hub/switch, you must implement it through the twisted-pair media using the physical pinouts shown in Table C-5.
