Fast EtherHub-12s User’s Guide
Connecting the Hub System
This hub is a Fast Ethernet repeater for 100BASE-TX networks. The EtherHub-12s has 12 RJ-45 station ports, of which Port 12 can serve as either a station port or a daisy-chain port (depending on the port’s switch setting). The station ports allow you to make connections to devices such as a workstation, server or router. You can also cascade to another compatible hub or switch by connecting an MDI port on one device (e.g., port 12MDI on this hub) to an MDI-X port on the other device. Or you can cascade from an MDI port on another device to any MDI-X port on this hub. See Figure 4.1.
Making a Connection via an MDI-X Station Port
You can connect an RJ-45 station port on the hub to any device that uses a standard network interface such as a workstation or server, or also to a network interconnection device such as a router (depending on the port type implemented).
1.Prepare the network devices you wish to network. Make sure you have installed suitable 100BASE-TX network interface cards for making a connection to any of the hub’s station ports. You also need to prepare
straight-through shielded or unshielded twisted-pair cables with RJ-45 plugs at both ends. Use 100W Category 5 cable for all connections.
2.Connect one end of the cable to the RJ-45 port of the network interface card (or comparable port type) on the device you are attaching to the hub, and the other end to any available (MDI-X) station port on the hub. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. Using the hub in a stand-alone configuration, you can network up to 12 nodes.
ΙDo not plug a phone jack connector into the RJ-45 port. This may damage the hub. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
Notes: 1. When connecting to station Port 12, set the port selection switch to MDI-X. 2. Make sure each twisted-pair cable does not exceed 100 meters.
