Introduction

Intended Audience: This manual assumes that the user has a general working knowledge of networking principles and is familiar with network systems in general.

Congratulations on the purchase of your Kingston Fast EtheRx Stackable 10/100TX Rack-MountableDual Speed hub. The KND2415TX is a full 19”rack-mountunit. The Fast EtheRx Stackable 10/100TXDual-Speedhub conforms to IEEE802.3u100BASE-TX,IEEE802.3i10BASE-T,and IEEE802.3 CSMA/CD standards. A maximum of four KND2415TX units can be stacked together.

IMPORTANT: The KND2415TX can only be stacked with other KND2415TX units. Stacking the unit with any other model hub may cause damage to the units.

For ease of installation, the Fast EtheRx Stackable Dual Speed hub offers twenty-four(24) UTP ports thatauto-negotiate10/100Mbps operation and an uplink port that allows the last UTP port on the hub to support both crossover andstraight-throughcabling. Ideal forinter-connecting10BASE-TEthernet networks with100BASE-TXFast Ethernet networks, the Fast EtheRxDual-speedhubs can also be used as simplestand-alone10BASE-Tor100BASE-TXrepeaters. For easytrouble-shooting,the front panel includes a variety of diagnostic LEDs such as Power, Collision for 10Mbps and 100Mbps, 100TX, Link, and Activity status.

Design Features

The Fast EtheRx dual-speedhub complies with the full set of repeater basic functions as de ned by IEEE802.3u100BASE-TX,IEEE802.3i10BASE-T,and IEEE802.3 CSMA/CD standards.

Repeater Functions

If any single port senses the start of a valid packet on its receiving line, the dual-speedhub willre-transmitthe received data to all other ports on the network. There-transmissionof packets complies with the IEEE 802.3 speci cation in terms of preamble structure, voltage amplitude, and timing characteristics.

Auto-Negotiation

Auto-Negotiationprovides the means of automatically establishing a link by detecting the link capabilities of the connected device on the network to select the best operational mode available (i.e. 10/100Mbps selection)

Receive Jabber Protection

The dual-speedhub uses a Receive Jabber Protection scheme to ensure that the network is not disabled due to reception of excessively long data packets.

Collision-Handling

The dual-speedhub will detect and respond to collision conditions as outlined in the IEEE 802.3 speci cations.

Error-Handling

With 100BASE-TXFast Ethernet, the newerror-handlingfeature preventssub-standardlinks from generating streams of false carrier and interfering with other links.

Automatic Port Partitioning / Reconnection

If any of the ports on the dual-speedhub experience excessive collisions, or faulty conditions, that particular port can be partitioned. Once partitioned, the hub will continue to monitor that port. If the error conditions have been corrected or a good data packet is received or transmitted without a collision, the hub will automatically reconnect that port to the network.

Hardware Installation

Hardware Installation

Before you begin installing network cables, please take a few minutes to familiarize yourself with the dual-speedhub. See the diagram below:

Front Panel

Fig. 3-1Front Panel

Power LED

The green LED indicates the power status. The LED will light up when the AC power connector is properly connected to a power source.

Collision LEDs

There are two (2) separate collision LEDs for both 10Mbps and 100Mbps segments. If a collision is detected on a 10Mbps segment, the “10” LED will ash amber. If a collision is detected on a 100Mbps segment, the “100” LED will ash amber. Collisions occur when 2 or more ports receive data simultaneously

100TX (Speed-Detection)LEDs

The 100TX LED lights up when 100Mbps operation is detected. The 100TX LED will not light up if 10Mbps operation is detected.

Link / Activity LEDs

The LINK / ACTIVITY LEDs service both 10BASE-Tand100BASE-TXoperation. A steady green light indicates that a good link has been established. Aashing green light indicates that data is being received.

If the Link LED does not display a steady green link light, please check the following:

1.Make sure the power is turned on for both the PC and EtheRx hub.

2.Verify that the correct network drivers have been loaded on the PC. Some network adapters require the drivers to be loaded to establish a proper link.

3.Make sure the correct cable type is selected.

4.Make sure the cable is wired properly and connected on both ends.

5.If steps 1 through 4 are correct, the cable may be defective or not wired correctly. Please refer to Appendix A for pin assignments and Appendix B for cabling guidelines.

10/100TX UTP Ports

The twenty-four(24) 10/100TX UTP portsauto-negotiateboth10BASE-Tand100BASE-TXconnections. . All ports like all normal hub ports are con gured asMDI-X.However, port 24, supports bothMDI-Xand MDI port con guration.

Uplink Port

The uplink port provides cabling exibility on UTP port 24 for connecting to a workstation NIC or cascading to another hub. Although these ports have two (2) UTP connections, MDI and MDI-X,only one port may be used.

Notes on MDI and MDI-XPorts

MDI (Media Dependent Interface) is the standard that de nes the mechanical and electrical con guration of a UTP port. For any two devices to communicate with each other, the transmitter of one device must be connected to the receiver of the other device.
