Q1. Do the hubs support full-duplex connections?
A1. No. Hubs are shared repeaters devices and cannot be connected to a device running in full-duplex mode. A full-duplex connection must be point-to-point not point-to-multipoint.
Q2. Can I daisy-chain hubs together with TPE cabling?
A2. If you are using the Intel® InBusiness™ hubs (10Mbps, 10BASE-T) you can daisy-chain up to 4 hubs together. The daisy-chain cable can be up to 100 meters long.
If you are using the Intel® InBusiness fast hubs (100Mbps, Fast Ethernet) you can daisy-chain up to 2 hubs together, but the daisy-chain cable can not exceed 5 meters in length.
Q3. How do I connect 100BASE-TX hubs to a 10Mbps device\segment?
A3. The preferred way to connect a 10Mbps segment or device to the 100Mbps segment or device is by using the Intel® InBusiness 8-Port Fast Hub Plus or 8-Port Switch Plus. Both of these devices have a built-in 10/100 bridge port that is capable of running at 10Mbps or 100Mbps.
Another inexpensive alternative is to use a file server to bridge the segments. Several LAN adapters on the market (such as the Intel® EtherExpress™ PRO/100+ LAN adapter) operate at either 10Mbps or 100Mbps. You can install two LAN adapters in your server and by connecting the 10Mbps segment to the first LAN adapter and the 100Mbps segment to the second LAN adapter allows the file server to route packets between the two segments. However, for this to work, your file server Network Operating System (NOS) must support routing. Novell NetWare* or Microsoft Windows NT* 4.0 do support routing. Microsoft Windows* 95 and Windows for Workgroups workstations do not have the capability to function as routing servers.
Q4. Is it possible to use the "Out to Hub" port and the last numbered port (5, 8 or 16) at the same time?
A4. No. The InBusiness hubs and switches are not designed for simultaneous operation on these ports. The "Out to Hub" port shares the same circuitry as the port it is next to and disables that port when a device is connected to the "Out to Hub" port. The "Out to Hub" port allows you to connect to another hub or switch without having to use a cross-over cable.
Q5. What is a 10/100 Fast Hub?
A5. 10/100 stands for 10Mbps and 100Mbps. This hub will autosense whether a 10Mbps or 100Mbps device is attached and set the speed accordingly.
Q6. What are the benefits of "autosensing" 10/100 devices?
A6. Autosensing hubs allow connection of either 10Mbps or 100Mbps devices. This allows you to connect your existing 10 Mbps devices and newer 100Mbps devices through one product.
Q7. Do the switches support full-duplex connections?
A7.Intel® InBusiness 4-Port Switch - Yes
Intel® InBusiness 8-Port Switch - Yes
Intel® InBusiness 8-Port Switch Plus - Yes, only on the 10/100 Bridge Ports (Ports A & B).
Intel® InBusiness 8-Port 10Mbps Switch - No
Intel® InBusiness 16-Port 10/100 Switch - Yes
Q8. What is the difference between a hub and a switch?
A8. See the document, Network Devices, for more information.
Q9. What type of cable do I need?
A9. See the document, Cable: Network Pipeline, for more information.
Q10. Is there a document that explains networking terms and acronyms?
A10. See the document, Glossary of Networking Terms, for more information.
