[. . . ] D-Link DFE-550FX 100Mbps Fiber-optics Adapter with SC Connector User's Guide First Edition (April, 2000) 6DFE550FX. 01 Printed in Taiwan RECYCLABLE Copyright Statement No part of this publication may be reproduced in any form or by any means or used to make any derivative such as translation, transformation, or adaptation without permission from D-Link Corporation / D-Link Systems Inc. , as stipulated by the United States Copyright Act of 1976. FCC Certifications 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. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] With ACPI, the operating system reduces motherboard and peripheral device power needs by activating devices only when they are needed. 802. 3x Flow Control The DFE-550FX implements IEEE 802. 3x compliant flow control for full duplex, which provides traffic management functions for full duplex operation. If the switch's data buffer is about to overflow when operating at full duplex, a Pause frame will be transmitted to the DFE-550FX. The ensuing idle time keeps the buffer from overflowing and prevents data from being lost. This enhancement can improve network throughput and prevent lost data, helping the network achieve optimal performance. In order for 802. 3x Flow Control to operate, your switch or hub must support this feature. In addition, some adjustments to the switch or hub settings may be needed. 1 D-Link DFE-550FX Adapter IEEE802. 1p Priority Tagging With the growing number of network applications, local area networks (LANs) must deliver data for a wide variety applications. Email, file transfers, database queries, voice over IP (VoIP), videoconferencing and multimedia must all be delivered to the enduser's. A slight delay in packet delivery can result in noticeable degeneration of video and audio quality, while other traffic, such as Email will not be noticeably affected by tiny delays. The large number of programs run over today's networks can impede the ability to deliver time-critical data. Even if available bandwidth is not usually a problem on your network, during peak hours bursts in network traffic can result in the delay of time-critical traffic. IEEE802. 1p defines eight levels of prioritization for Ethernet packets. High priority packets will be sent through a network using 801. 2p-compliant switches first. Lower priority packets will be transferred when bandwidth is available. However, it is good practice to eliminate static charges by touching a sizable metal object before handling the adapter card. Open the shipping carton and carefully remove all items. In addition to this User's Guide, ascertain that you have: · · One DFE-550FX Adapter. If your order does not include the Boot ROM option, go ahead to Step 3. If your order includes the Boot ROM option, then install the Boot ROM Chip by plugging the chip into the Boot ROM Socket on the DFE-550FX card. The notched end of the Boot ROM Chip must be aligned with the notched end of the Boot ROM Socket. Firmly insert the contact edge of the DFE-550FX card into any 3. 4 D-Link DFE-550FX Adapter available PCI Bus expansion slot. If the BIOS section of your computer boot program is Plug and Play compliant, then at power-up the BIOS will automatically configure itself for the newly installed DFE550FX adapter. NOTE: Due to a fault in some Plug-n-Play BIOS programs, it happens occasionally that a newly installed adapter is assigned an IRQ Number which is already assigned to another device. In such a case, the conflicting IRQ Numbers (IRQ numbers must be unique) will cause faults in the behavior of both devices. If this happens, it is necessary to run the CMOS Setup utility, and manually assign a nonconflicting Interrupt Number to the DFE-550FX. Connecting the Network Cable Multimode (62. 5/125µm or 50/125µm) fiber cabling with an IEEE recommended SC connector is required for the adapter. [. . . ] Observe the Packets Sent and Packets Received lines to see that they track together (always showing equal count numbers), which verifies normal network operation. The most likely causes of failure for any of the diagnostic tests are incorrect options settings, option settings that conflict with the settings of other boards or improper installation. In the event of any failure in diagnostic tests, refer to the Troubleshooting section of this guide. 8 D-Link DFE-550FX Adapter Troubleshooting If you experience any problems with the adapter, first verify that the appropriate driver is loaded, that the proper grade of cable is employed for the network connection, and that the supporting hub is functioning properly. Ascertain that the adapter card is fully and firmly seated in the slot connector. Ascertain that the adapter PCI slot is not deactivated at the BIOS level. [. . . ]
