Compaq Technician Notes And Customer Support
Compaq Technician Notes
WARNING: Only authorized technicians trained by Compaq should attempt to repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module level repair. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. Any indications of component replacement or printed wiring board modifications may void any warranty.
WARNING: To reduce the risk of personal injury from electrical shock and hazardous energy levels, do not exceed the level of repair specified in these procedures. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs could create conditions that are hazardous.
WARNING: To reduce the risk of electric shock or damage to the equipment:
- If the system has multiple power supplies, disconnect power from the system by unplugging all power cords from the power supplies.
- Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
- Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
CAUTION: To properly ventilate your system, you must provide at least 12
inches (30.5 cm) of clearance at the front and back of the computer.
CAUTION: The computer is designed to be electrically grounded. To ensure
proper operation, plug the AC power cord into a properly grounded AC outlet
only.

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 computers are capable of producing energy levels that are considered hazardous. Users should not remove enclosures, nor should they bypass the interlocks provided for removal of these hazardous conditions.
- Installation of this adapter should be performed by individuals who are both qualified in the servicing of computer equipment and trained in the hazards associated with products capable of producing hazardous energy levels.
NOTE: Before removing the cover of your server, refer to the Compaq documentation for the proper methods for installing a PCI card and avoiding electric shock hazards.
Electrostatic Discharge Precautions
A discharge of static electricity from a finger or other conductor can damage components on the adapter. This can make the adapter inoperable. In addition to the following information, see Appendix B for more precautions. To prevent electrostatic damage, observe the following precautions:
- Always properly ground yourself when touching a static-sensitive component or assembly.
- Avoid hand contact by transporting and storing parts in static-safe containers.
- Keep electrostatic-sensitive parts in their containers until they arrive at static-free locations.
- Place parts on a grounded surface before removing them from their containers.
- Avoid touching pins, leads or circuitry.
Installing the Adapter in a Server
Refer to the documentation provided with your server for the specific steps necessary to safely install a PCI card in your server.
- If the server is not PCI Hot Plug compliant, power down the server and unplug the power cord.
- Remove the server cover and the cover bracket from a PCI slot.
- WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components to cool before touching them.
- CAUTION: If the device is not PCI Hot Plug compliant, power down the device and unplug the power cord rom the power outlet before removing the device cover. Failure to do so may damage the adapter or computer.
- Firmly seat the adapter in a PCI slot and secure the adapter bracket.
- Replace the server cover and plug in the power cord.
Connecting the Network Cable
- Network connections for the NC3120 Server Adapter can employ existing UTP Category 5 (or better) cable for 100 Mb/s transmissions, and UTP Category 3 (or better) cable for 10 Mb/s transmissions.

Appendix B Electrostatic Discharge
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.
- Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
- Place parts on a grounded surface before removing them from their containers.
- Avoid touching pins, leads, or circuitry.
- Always be properly grounded when touching a static-sensitive component or assembly.
Grounding Methods
- There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:
- Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
- Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.
- Use conductive field service tools.
- Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have a Compaq authorized reseller install the part.
NOTE: For more information on static electricity or assistance with product installation, contact your Compaq authorized reseller.

- Category 3 (or better) UTP twisted-pair
- 22-26 AWG, 100Ω at 1MHz
- EIA/TIA 568a or EIA/TIA 568b

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 or switch, or externally through the twisted-pair media.
10/100 Straight-Through Pinouts
If the crossover function is implemented internally, the port is labeled MDI-X (Medium Dependent Interface–Crossover). When an MDI-X port is connected to an MDI port, the twisted-pair media should be wired straight-through using the physical pinouts indicated in Table C-2.
Table C-2
10/100 Pinouts Using Internal, Straight-Through Crossover
Pin| Function| Color Match| Function| Pin
1| TD+| White/Orange| TD+| 1
2| TD-| Orange/White| TD-| 2
3| RD+| White/Green| RD+| 3
4| | Blue/White| | 4
5| | White/Blue| | 5
6| RD-| Green/White| RD-| 6
7| | White/Brown| | 7
8| | Brown/White| | 8
- Figure C-1 shows the straight-through 10/100 connector wiring to be used when the crossover function is implemented on the hub or switch.
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.
Table C-3
10/100 Pinouts Using External Crossover
Pin| Function| Color Match| Function| Pin
1| TD+| White/Orange| RD+| 3
2| TD-| Orange/White| RD-| 6
3| RD+| White/Green| TD+| 1
4| | Blue/White| |
5| | White/Blue| |
6| RD-| Green/White| TD-| 2
7| | White/Brown| |
8| | Brown/White| |
- Figure C-2 shows the correct 10/100 wiring to use when the crossover function is implemented externally in the twisted-pair cabling.
