EtherHub-16 Quick Start Guide

Smart Ethernet Hub with 16 RJ-45 Ports and AUI/BNC Ports

This 10 Mbps Ethernet hub includes 16 RJ-45 ports on the front panel, as well as AUI and BNC

ports on the rear panel. This hub can be operated in a stand-alone configuration, cascaded to

other hubs, or linked to an AUI/BNC backbone. This hub is suitable for desktop or rack-mount

installation, and supports full-range power input. The EtherHub-16 conforms to the IEEE 802.3

standard for local area networks based on CSMA/CD, and provides10BASE-T, 10BASE2 and

AUI repeater functions including:

• Signal amplification and retiming

• Preamble regeneration and fragment extension

• Automatic port partition and reconnection

Hardware Installation

The EtherHub-16 has 16 RJ-45 ports, of which Port 16 can serve as either a standard port or a

daisy-chain port. It also has AUI and BNC ports. Use twisted-pair cable (100W STP or UTP) to

connect any standard RJ-45 (MDI-X) port to a server/workstation, or to connect the RJ-45 daisy-

chain port (i.e., Port 16MDI) to another compatible hub or switch. You can also attach to an

Ethernet LAN backbone by connecting thin coaxial cable to the BNC port or by connecting thick

coaxial cable to the AUI port.

Making RJ-45 Connections

1. Prepare straight-through twisted-pair cable (100W) with RJ-45 plugs at both ends. The

length of each cable should not exceed 100 meters (328 feet).

Do not plug a phone jack connector into any RJ-45 port. This may damage the hub. Instead,

use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

EtherHub-16 Quick Start Guide 2. If you are making a connection to an end-node device (e.g., a PC or server), be sure that it has a properly installed 10BASE-T network interface card. Attach one end of a straight-through twisted-pair cable to any standard port (Port 1 ~ 16MDI-X) on the hub and the other end to the RJ-45 port of the other device’s network interface card. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position, to ensure that it is properly seated.

EtherHub-16 Quick Start Guide System Configuration The EtherHub-16 provides standard RJ-45 ports for attaching end-node devices such as a workstation or server, a daisy-chain port for cascading to another hub or switch, a BNC port for attaching a thin Ethernet backbone, and an AUI port for attaching a thick Ethernet backbone or a fiber optic link (via the appropriate transceiver). The following figure illustrates some of the possible network configurations and cabling restrictions that apply to this hub.

EtherHub-16 Quick Start Guide Daisy-Chain Port A compatible hub or other network interconnection device (e.g., an Ethernet switch) can be attached to the daisy-chain port (Port 16MDI). Use straight-through twisted-pair cable (STP or UTP) to connect to a standard MDI-X port on the target device. Up to 4 hubs can be cascaded in this manner. To connect to another hub, you may also run twisted-pair cabling from an MDI-X port on this hub to an MDI daisy-chain port on another hub.
