Connecting to a 10 Mbps segment

The Express Switching Hub is a 100 Mbps-only switch. You can’t connect a 10 Mbps device directly to the switch.

The preferred way to connect the segments is by using a bridge, router, or a 100 Mbps uplink module for your 10 Mbps hub (there isn’t a 10 Mbps uplink module available for the Express switching hub). However, this is costly if you don’t already have the equipment. An inexpensive alternative is to connect the segments through a server.

NOTE

Windows NT* 3.51 doesn’t include the multi-protocol router software by default. You can download it from the Microsoft World Wide Web site.

Several adapters on the market (such as the Intel EtherExpress PRO/ 100 adapter) operate at either 10 or 100 Mbps. By connecting the Express 100BASE-TX Switching Hub to one server adapter at 100 Mbps and your 10BASE-T hub to a separate adapter at 10 Mbps in the same server, you can route traffic from the 10 Mbps segment to the 100 Mbps segment through your Network Operating System (NOS).

If your NOS doesn’t support multi-protocol routing (Windows 95 peer-to-peer and Windows for Workgroups* don’t), you must use a Fast Ethernet switch or router that supports both 10 Mbps and 100 Mbps.
