1 Introduction Overview The HP NC7770 PCI-X 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 HP NC7770 adapter has one auto-negotiating RJ-45 port and LED indicators showing link, activity, and port speed. The NC7770 PCI-X Gigabit Server Adapter is a supported option for selected HP ProLiant servers.
Introduction LED Indicators The following table describes the LED indicators located on the front panel of the HP NC7770 Server Adapter. Table 1-1: 10/100/1000 LED Operations for the NC7770 Adapter LED Display Description 1000 On Link to the adapter is established. The adapter is sending or receiving network data at 1000 Mb/s. Off The adapter is not sending or receiving network data at 1000 Mb/s. On Link to the adapter is established. The adapter is sending or receiving network data at 100 Mb/s.
2 Installing the Adapter Overview 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 installation of the adapter. Many servers are capable of producing energy levels that are considered hazardous.
Installing the Adapter Installing the Adapter in a Server Refer to the HP 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 WARNING: If the server is not PCI Hot Plug compliant, power it down and unplug the power cord from the power outlet before removing the server cover. Failure to do so may damage the adapter or server. 1. Remove the server cover and cover bracket from a PCI slot.
Installing the Adapter Connecting the Network Cable Network connections for the NC7770 Server Adapter can employ existing Category 5 UTP (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.
A Regulatory Notice Federal Communications Commissions Notice Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules.
Regulatory Notice Class B Equipment 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. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
Regulatory Notice For questions regarding this FCC declaration, contact: Hewlett-Packard Company P. O. Box 692000, Mail Stop 510101 Houston, Texas 77269-2000 Or, call (281) 514-3333 To identify this product, refer to the Part, Series, or Model number found on the product. Canadian Notice (Avis Canadien) Class A Equipment This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.
Regulatory Notice European Union Notice Products bearing the CE marking comply with the EMC Directive (89/336/EEC) and the Low Voltage Directive (73/23/EEC) issued by the Commission of the European Community and if this product has telecommunication functionality, the R&TTE Directive (1999/5/EC).
Regulatory Notice Japanese Notice PCI-X Notice When this product is used in PCI-X mode, it is a “Class A” device.
B Electrostatic Discharge Overview 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.

Specifications UTP Cable Specifications To connect to the network, the NC7770 Server Adapter uses the following cable for 1000BASE-T transmission. Category 5 UTP or better 22-26 AWG, 100Ω @ 1MHz EIA/TIA 568a or EIA/TIA 568b Using UTP Category 5 Cable in Gigabit Over Copper Installations For Gigabit over copper installations, Category 5 UTP or better 1000BASE-T cable must comply with the IEEE 802.3ab 1000BASE-T standard.
Specifications Figure C-1: 10/100 straight-through wiring for RJ-45 connector 10/100 Crossover Pinouts When the crossover function is not provided within the hub or switch, you must implement the crossover through the twisted-pair media using the physical pinouts indicated in Table C-3.
Specifications Gigabit over Copper Internal StraightThrough Pinouts Unlike connections in which the crossover function is implemented internally at the hub or switch, the NC7770 Server Adapter provides its own automatic crossover function. This means you can wire twisted-pair media straight-through for adapter-to-hub, adapter-toswitch, or adapter-to-adapter connections using the pinouts shown in Table C-4.
