Introduction

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

Congratulations on the purchase of your Kingston EtheRx WorkGroup (WG) series100BASE-TXFast Ethernet hubs. There are two models available in this series: KNE4TX/WG, which is the4-Portmodel, and KNE8TX/WG, which is the8-Portmodel. The EtheRx Workgroup series hubs are ClassII repeaters that conform to IEEE 802.3u100BASE-TXstandards. Please refer to Appendix D for further information on ClassII repeaters.

The EtheRx Workgroup hubs support up to four (4) or eight (8) UTP (Unshielded Twisted-Pair)ports for100BASE-TXnetwork connections. Both models include a cascade switch on the last UTP port (Port 4 or Port 8) which supports bothstraight-throughand crossover cable types. The UTP ports usedual-colorLEDs to showthree states of operation: link, activity and partition/error. The EtheRx hubs also include a collision LED for collision detection and five (5) utilization LEDs to display the level of network traffic in percentages of the total available bandwidth.

For the remainder of this manual, the KNE4TX/WG (4-portmodel) and the KNE8TX/WG(8-portmodel) hubs will be referred to as the EtheRx hubs.

Design Features

The EtheRx hub complies with the full set of repeater basic functions as defined by IEEE 802.3u. These functions include all Repeater Functions, Signal Regeneration, Receive Jabber Protection, Collision-Handling,ErrorHandling, and Auto Partitioning/Reconnection.

Repeater Functions

If any single port senses the start of a valid packet on its receiving line, the EtheRx hub will re-transmitthe received data to all other ports on the network. There-transmissionof packets complies with the IEEE 802.3u specification in terms of preamble structure, voltage amplitude, and timing characteristics. These timing regenerations prevent cumulative signal loss, jitters, and distortion caused by network cabling, thus allowing the EtheRx hubs to be cascaded to other100BASE-TXClassII repeaters.

Receive Jabber Protection

The EtheRx hub provides a Receive Jabber Protection scheme to ensure that the network is not disabled due to reception of excessively long data packets. This protection scheme will automatically interrupt the receiver if the EtheRx hub has been continuously receiving for more than 65,536-bittimes.

Collision-Handling

The EtheRx hub will detect and respond to collision conditions as outlined in the IEEE 802.3u specifications.

Error-Handling

The 100BASE-TXstandard uses an improved method oferror-handlingcalledblock coding. With100BASE-TXFast Ethernet, the newerror-handlingfeature prevents substandard links from generating streams of false carrier and interfering with other links.

Automatic Port Partitioning/Reconnection

If any of the ports on the EtheRx hub 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 without a collision, the hub will automatically reconnect that port to the network.

Power LED

The green LED indicates the power status. The LED will light up when the unit is properly connected to the accompanying DC power supply. For further details, please refer to Figure 1-8 on page 8.

Kingston Technology Company

KNExTX/WG User’s Guide - Rev. A00

Utilization LEDs

The five Utilization LEDs display the rate of network traffic in percentages of the total available bandwidth. The amount of data traffic is measured in frames per second (FPS), then calculated into percentage values: 1%, 12%, 25%, 50%, and > 60%. The appropriate LED will light up based on network activity.

Collision LED

If a collision is detected on the network, the Collision LED will flash amber. A collision occurs when the hub receives data from two or more nodes simultaneously.

4 or 8 UTP Port LEDs

The LINK/ACTIVITY/PARTITION LEDs use two colors to display three states of operation for the 4 or 8 UTP ports. If a good link is established on any given port, the LED will light up steady green, indicating a valid network connection between the network node and the hub. If the LED does not display solid green indicating a good link, check the following:

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

2.Verify the network adapter has loaded its drivers from 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 thru 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.

A flashing green light indicates when data is being received. A flashing amber light indicates one of the following occurences:

1.A port has been partitioned due to an excessive number of collisions or

2.A port has encountered errors due to invalid packets or jabber conditions.

Cascade Switch

The Cascade Switch provides cable wiring flexibility on the last UTP Port (i.e., Port 4 or Port 8) for connecting to a workstation or cascading to another hub. By default, the last UTP port is set to “Crossover” (left side) as a standard, internally-crossedport, orMDI-Xport. Depending on the wiring of your UTP cable (normally“Straight-Through”),the port is used to connect a workstation. For cascading to another ClassII repeater using astraight-throughcable, move the Cable Switch to“Straight-Through”(right side). If a crossover UTP

cable is used to cascade to another Class II repeater, leave the Cable Switch in the “Crossover” position. See Figure1-4for a diagram showing the cascade

switch settings. To verify the pin wiring of your UTP cable, refer to

“Appendix B Cabling Guidelines” on page 11.

Notes on MDI and MDI-XPorts

MDI (Media Dependent Interface) is the IEEE 802.3 standard for the interface to the UTP cable. For two 100BASE-TXdevices to communicate with each other, the transmitter of one device must be connected to the receiver of the other device. This can be achieved by using a crossover cable, or by using oneMDI-Xport that implements thecross-overinternally.

4 or 8 UTP Ports

The UTP ports are numbered 1 through 4 or 1 through 8 for 100BASE-TXconnections. Since crossover function is implemented on all UTPMDI-Xports, astraight-throughUTP cable should be used. (Note: Port 4 and Port 8 support both cable types using the cascade switch. Refer to Appendix A & B for details onRJ-45pin assignments and cable guidelines.

DC Power Connector

The EtheRx hub gets its power from the auto-sensingpower supply. Insert the power jack into the DC power connector located to the far right. For safety purposes, ONLY use the included power supply for proper operation. The wrong type of power supply may cause damage to both the EtheRx hub and the power supply.(NOTE: The power supply output voltage is 5VDC/2.0A.

Polarity on the power jack and DC power connector is negative (-)on the outside and positive (+) on the inside.)

Cable Wiring Standards

There are two governmental agencies: the Electronic Industry Association (EIA) and the Telecommunications Industry Association (TIA), which set the standard for all cable wiring requirements for commercial buildings. For 100BASE-TXnetworks, Category (CAT) 5 should be used.

With the advent of 100Mbit network products, it is best to use higher quality CAT 5 cables like Belden or Helix as well as CAT 5-compliantpatch panels and connectors while following the EIA/TIA wiring standards. 100 Ohm UTP/STP CAT 3, 4 & 5 type cables use4-pairUTP wiring.

Refer to the illustrations on page 12 for standard 100BASE-TXwiring and 4- pair 100Mbit wiring using either T568A (TableB-3)or T568B (TableB-4)wiring standards. Both T568A and T568B wiring configurations are compatible with10BASE-Tand100BASE-TXand require no special hardware configurations. However, it is highly recommended that only one wiring scheme be used in premise wiring to avoid potential problems.

Rating Codes

UTP cables meet different UL-NECrequirements based oncable-jacketquality. Below is an explanation of the rating codes for each cable type.

UL – The National Electrical Code (NEC), published by the National Fire Protection Association (NFPA), details advisory safety considerations for electrical wiring. NEC Article 800 Communications Cables are manufactured to meet these different cable types.

1.CMP – Cables meeting type CMP requirements are suitable for installation in ducts and plenums without the use of conduit. These cables are designed for fire resistance andlow-smokeproducing characteristics.

2.CMR – Riser type cables are engineered to prevent the spread of fire from floor to floor and are suitable for vertical shaft applications.

3.CM – Cables for general building wiring. CM cables are used in areas other than plenums and risers. These cables are resistant to the spread of fire and pass the UL 1581Vertical Tray Flame Test.

4.MP, MPR &MPP – Within Article 800, theMulti-purposeCables Category, allows conditional substitutions between different cable types & are restricted by number, AWG size and stranding of the cable conductors.

Terms You Should Be Familiar With

1.BACKBONE WIRING – The physical/electrical interconnections between telecommunications closets and equipment rooms.

2.COMPLIANCE – A wiring device that meets all characteristics of a standard is said to be in compliance with that standard.

3.TWISTED PAIR (UTP) – Two insulated copper wires twisted around each other to reduce interference from one wire to the other. The twists are varied in length to reduce the potential for signal interference between pairs. Several sets of twisted pair wires may be enclosed in a single cable.
