You need to be using  the correct type of cable.  In this case, a “Crossover” cable is needed in order to link the two computers together.  If you have a hub between the computers, you would use a regular “Straight Through” RJ45 cable.

What operating systems are supported with the external USB to Fast Ethernet Converter? (return to top)

Windows 98/Me and Windows 2000 are compatible with the external converter.

What is the maximum speed at which the adapter can transfer data? (return to top)

The Fast Ethernet Converter is compatible with 10/100Mbps networks.  It follows the USB standard with a 12Mbps maximum throughput.

Power indicator does not light up (green) after power on. (return to top)

The likely cause is that there is a defective power outlet, power cord, or internal power supply.   Try a different outlet or have your unit's power supply or Power LED replaced. 

My hub powers off after running for a while. (return to top)

Check for loose power connections, power losses or surges at the power outlet, and verify the fan on back of the unit is unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective.

The partition indicator lights up on my hub. (return to top)

The hub automatically partitions a port that is due to a faulty cable or connector or when there are excessive collisions on the segment it is connected to.  When the faulty condition disappears, the hub will automatically enable the partitioned port.

Link/traffic indicator remains off after a connection has been established. (return to top)

Network interface (e.g., a network adapter card on the attached device), network cable, or hub port may be defective.

• Verify that the hub and attached device are powered on.  Be sure cable is plugged into both the hub and corresponding device.
• Verify that the proper cable type is used (See the installation guide), and that its length does not exceed 100 meters.
• Check the adapter on the attached device and cable connections for possible defects.  Replace the defective adapter or cable if necessary.

My hub is 15 feet away from my server and I have no problems accessing it.  However, when I move the hub 50 feet away, I lose my connection.  I have already checked the cables and connectors to ensure they are good.

Using the same cable in a 10Mbps environment, there is no any problem.  We have discovered that this problem only occur in a 100Mbps environment.  In a 10Base-T LAN, the frequency of the signal is 20MHz, but the 100Base-TX transmits at 41.6MHz signal.  In such a condition, cross-talk occurs.

Cross-talk occurs because the cable has incorrect wired pairs.  The correct cable wiring should have two wired pairs: Pin 1/Pin 2 must be twisted and Pin 3/Pin 6 must be twisted.

My FH8DS+ hub has a noisy sound coming from the fan. (return to top)

The cooling fan is defective.  Contact your Ovislink distributor for a replacement fan.

I have two computers directly connected to each other using a UTP RJ45 cable. The configurations of the Ethernet card  and driver in Windows 98 look okay.  Each computer can see itself in Network Neighborhood, but cannot see the other computer.  What's the problem? (return to top)

Make sure you are using the correct type of cable. In this case, a “Crossover” cable must be used in order to link the two computers together.  If you have a hub between the computers, you would use a regular “Straight Through” RJ45 cable.

What is Gigabit Ethernet technology?  How does it relate to 10/100Mbps Ethernet? (return to top)

Gigabit Ethernet is an extension to the enormously successful 10 and 100Mbps 802.3 Ethernet standards.  Gigabit Ethernet will provide a raw data bandwidth of 1000 Mbps while maintaining full compatibility with the installed base of over 70 million Ethernet nodes.  Gigabit Ethernet will include both full- and half-duplex operating modes.  In the case of half duplex, Gigabit Ethernet will retain the CSMA/CD access method.  Initial products will be based on the Fiber Channel physical signaling technology, appropriately adapted for a data rate of 1000 Mbps running over fiber-optic cabling.  Advances in silicon technology and digital signal processing will eventually enable cost effective support for gigabit Ethernet operation over Category 5 unshielded twisted-pair (UTP) wiring.

Why is Gigabit Ethernet necessary?  Isn't Fast Ethernet good enough? (return to top)

A Gigabit Ethernet is imperative for two reasons: faster systems and faster backbones.  As Fast Ethernet makes its transition to a widespread desktop technology, a faster backbone network is necessary, and Gigabit Ethernet technology fills that need perfectly.  As systems get even faster, and technology improves, Gigabit Ethernet will migrate to the desktop.  Simply put, faster systems require faster networking, input/output (I/O), memory throughput, and access to larger memory and storage in order to remain balanced.  Fast Ethernet is a good match for today's midrange and high-end systems, but systems over the next several years will be able to utilize an order of magnitude more bandwidth.

What are the end-user benefits? (return to top)

A Benefits of Gigabit Ethernet include the potential for low-cost products, freedom of choice in selecting the products, interoperability, and backward compatibility.  The Gigabit Ethernet technology is an extension of the 10/100-Mbps Ethernet standard.  Gigabit Ethernet will support existing applications, network operating systems, and network management; it requires a minimal learning curve for Ethernet network administrators and users.  These investment preservation and risk minimization aspects are what make Gigabit Ethernet so attractive.

How does Gigabit Ethernet fit into existing networks? (return to top)

A Gigabit Ethernet will be fully compatible with existing networks and preserve user investments in applications, network operating systems, protocols, and network management.  Gigabit Ethernet will preserve the 802.3 and Ethernet frame format, and the 802.3 managed object specifications.  Therefore, users can migrate easily to Gigabit speeds with existing applications, network operating systems, protocols, and network management.  Gigabit Ethernet will provide increased bandwidth in those portions of the network where it is needed, while exhibiting seamless integration with a customer's existing Ethernet infrastructure.

What are the distance characteristics of Gigabit Ethernet? (return to top)

A In principle, there is no limit to the size of a Gigabit Ethernet network, in terms of either physical extent or number of nodes.  Like Fast Ethernet and the original 10-Mbps Ethernet, Gigabit Ethernet will support a variety of physical media, with different capabilities in terms of maximum link distance.  The IEEE 802.3 Higher-Speed Study Group has identified three specific objectives for link distance: A multimode fiber-optic link with a maximum length of 500 meters; a single-mode fiber-optic link with a maximum length of 2 kilometers; and a copper-based link with a maximum length of at least 25 meters.  The IEEE is also actively investigating technology that would support link distances of at least 100 meters over Category 5 UTP wiring.

How does Gigabit Ethernet compare to Fiber Channel? (return to top)

A Gigabit Ethernet seeks to leverage existing solid technologies, and therefore leverages Fiber Channel's physical layer.  The difference is that Gigabit Ethernet is a general-purpose networking technology useful for small to large LANs, whereas Fiber Channel is used primarily in more specialized applications like high-speed I/O (storage), clustering, and so on, where a general-purpose LAN is not needed.  Fiber Channel is an excellent technology for these applications, but tends to be more expensive per port and is optimized for these types of connections.  Gigabit Ethernet will leverage the Ethernet/Fast Ethernet cost models and be optimized for general-purpose networking.
