1. Introduction KF-8D dual-speed Fast Ethernet/Ethernet hub is designed to allow easy and flexible migration from 10Mbps Ethernet to 100Mbps Fast Ethernet. The hub complies with IEEE 802.3 and IEEE 802.3u repeater specifications and supports 10Mbps and 100Mbps con- nectivity over UTP cabling in the same hub. The hub provides 8 dual-speed TP ports. All of the TP ports support auto-sensing function that allows the hub to detect the connection speed auto- matically. The hub also provides complete d

Dual-speed Hub Technology Dual-speed hub is designed to support connections with different speeds in the same hub. It makes a network planning simpler, espe- cially when an environment is containing 10Mbps Ethernet and 100Mbps Fast Ethernet technologies. It also allows a smooth mi- gration from an Ethernet network to a Fast Ethernet network. A dual-speed hub is actually equipped with one 10Mbps repeater and one 100Mbps repeater in one hub unit. Each repeater serves one shared network segment. Th

2. Installation Unpacking Check to see that you have everything before you start the installation. • Installation guide • The hub unit • One AC power adapter for the hub • One wall mount kit Checking AC Power Before you begin the installation, check the AC voltage of your area. The AC power adapter which is used to supply the DC power for the hub should have the AC voltage matching the commercial power volt- age in your area. The specifications of the AC power adapter are: • AC input power: AC p

The power socket for the AC power adapter is located on the rear of the hub as shown below: Mounting the Hub The hub can be placed on a desktop as a stand-alone unit. It also can be mounted on a wall. The following procedure describes how to mount the hub onto a wallboard or wood (a stud, heavy wooden paneling, etc.) using the wall mount kit supplied in the hub package: 1. Using the slot bracket and two washer-head screws in the wall mount kit, screw the slot bracket onto the bottom of the hub i

3. Making Network Connections Network Connectors and Rear Switch The hub provides 8 dual-speed TP ports. Each can support one con- nection to either a 10BASE-T Ethernet device or a 100BASE-TX Fast Ethernet device using 2-pair UTP cable. One configuration switch is located on the rear panel. The switch is used for setting the operation mode for the hub. Three selections are available as follows: AUTO mode Set all TP ports to be auto-sensing ports 100M mode Set all TP ports to be 100BASE-TX ports

RJ-45 Connectors Each of Port #1 to Port #7 provides one RJ-45 connector, which are implemented as MDI-X jack. An MDI-X jack is designed with internal crossover function. The function allows a connection to a computer using straight-through UTP cable. The Port #8 provides one MDI-X RJ-45 connector and one MDI-I RJ-45 connector. Only one connector can be used at the same time. The pin definitions for MDI-X jack and MDI-I jack are as follows: PIN# MDI-X Jack MDI-I Jack 1 Rx+ Tx+ 2 Rx- Tx- 3 Tx+

Connecting to Computers The RJ-45 connectors labeled 1X to 8X can be used for connecting to the network adapter installed in a computer. The network adapter can be a 10BASE-T adapter, a 100BASE-TX adapter, or a 10/100 dual-speed NWay adapter. The following table lists the cables used for connecting to different network adapters: Adapter connected UTP cable used Maximum length 10BASE-T adapter Category 3, 4 or 5 100 meters 100BASE-TX adapter Category 5 100 meters 10/100 NWay adapter Category 5 1

Connecting to a Fast Ethernet Hub Since the KF-8D is designed to comply with IEEE 802.3u Class II repeater specifications, it can support one connection to another 100BASE-TX Class II hub. The connection rules are: 1. The other hub which is connected to KF-8D must comply with IEEE 802.3u Class II repeater specifications. 2. No more than two hubs can be cascaded in the network. The following figure illustrates the maximum Fast Ethernet network expansion using two KF-8D hubs: 11

4. Interpreting LED Indicators The following figure shows the locations of the LED indicators: Power LED: indicates the status of the repeater power source. State Indication Interpretation On Normal The power of the hub is on. Off Problem No power is being supplied to the hub. Collision LED: indicates the collision detected by the hub. The LED is normally off and it blinks when there are collisions on 10M shared segment or 100M shared segment. Link/Rx 1-8 LED: indicates the link status and rece
