Page 25: B General Information
General Information This appendix provides general system specifications and cabling requirements for the Fast EtherWORKS/PMC Adapter module. Physical Description The PMC Adapter module is a PMC that uses the 32-bit PCI bus connector. The module measures 149 mm by 74 mm, and is constructed using four-layer circuit board technology with two signal layers and two power/ground layers. -
Page 26: Leds
LEDs The LEDs are used to indicate the status of the module and its connector. These LEDs are visible on the module’s front panel (at the back of your system). During diagnostics, the module’s Activity LED blinks once, then remains lit. Once the network software and device driver(s) are loaded, the LEDs reflect status. -
Page 27: Operating Environment
Caution When you add adapter modules to your computer, verify that the combined power (wattage) required for the modules does not exceed the power supply rating. Refer to your computer documentation for this information. Operating Environment Table B–3 lists the recommended operating environment specifications for the PMC Adapter module. -

Page 31: Cabling Requirements
Cabling Requirements Use one of the following cable types, or its equivalent based on the module variant, to connect the PMC Adapter module’s cable to the network. The AA variant uses unshielded cables and the AC variant requires shielded cables. The maximum length supported by the Ethernet is 100 meters of cable for both speeds. -
Page 33: C Fast Ethernet Technology
Fast Ethernet Technology The increased performance and capacity of personal computers along with the availability of cost-effective, high-resolution peripherals have fueled the development of high-performance, data-intensive applications such as graphical user interfaces, computer-aided engineering, computer-aided training, groupware, image processing, document management, network resource libraries, and multimedia. The effective utilization of these new, high-performance systems at the desktop demands new low-cost, high-performance LAN interface technologies. -
Page 34: Advantages Of Fast Ethernet
Advantages of Fast Ethernet Key advantages of the Fast Ethernet are: • High performance • Standards-based technology • Cost-effective migration • Vendor support High Performance One of the compelling reasons to choose Fast Ethernet for workgroups is the ability to handle both the aggregate demands of multiple LAN users and the peak traffic created by today’s high-performance PCs and sophisticated bandwidth-intensive applications. -
Page 35: Cost-Effective Migration
Cost-Effective Migration The seamless compatibility between 10BASE-T and 100BASE-T allows easy migration to high-speed connects. Migration is simple and economical in many important areas: • LAN cabling—100BASE-T media specifications (100BASE-TX, 100BASE-FX, and 100BASE-T4) enable Fast Ethernet to run on the most common Ethernet wiring, including Categories 3, 4, and 5 unshielded twisted-pair (UTP), shielded twisted-pair (STP), and fiber. - Page 36 Summary Although not all users require 100 Mb/s network performance to the desktop today, many LAN-intensive applications already push the limits of existing 10 Mb/s LANs, and can benefit from 100 Mb/s technology now. Emerging data-intensive applications and technologies (such as multimedia, groupware, imaging, and client- server databases) make 100 Mb/s networking a critical part of most LANs.
