Page 7: Introduction
1. Introduction This guide covers the product information and installation information for two dual speed Fast Ethernet hubs. One is KF-16M which provides 16 dual-speed twisted-pair (TP) ports. The other is KF-16MS which provides 16 dual-speed TP ports and one internal 10M-to-100M switch for bridging the 10Mbps network and 100M network in the hub. -
Page 8: Features
Both hubs also feature cascade connectors (two for KF-16M, one for KF-16MS) on the rear for cascading one hub to another in a hub stack. Up to four hubs can be cascaded in one stack. A hub stack can be treated as a single hub which gives a total of 64 dual-speed TP ports with only one hop count. -

(10M or 100M) of its connection and switch to either 10Mbps shared segment or 100Mbps shared segment automati- cally. The internal design of a dual-speed hub, KF-16M, is illustrated as follows: Figure 1-2 Dual-speed Hub Design... -
Page 10: Dual-Speed Hub With Built-In 10/100 Switch
KF-16MS is equipped with an internal 10M-to-100M switch function to bridge the traffics between 10Mbps segment and 100Mbps segment as follows: Figure 1-3 Dual-speed Hub with Built-in 10/100 Switch The 10M-to-100M switch can perform packet forwarding from one seg- ment to another at wire speed. It also performs the address filtering that only forwards those packets which need to cross 10M and 100M seg- ments. -

Page 12: Installing The Dual-Speed Hub
2. Installing the Dual-speed Hub The hub is designed to operate in workgroup environments without a complicated configuration procedure. It also features an auto-select 100- 240V, 50/60Hz power supply unit, which works in most countries around the world. Before connecting the supplied power cord into the hub, check to see that the cord voltage and current rating conform to the standards of the country of operation. -

Rack Mounting For mounting the hub into a 19-inch rack, a pair of mounting brackets is included in the pack. Figure 2-2 Install Rack Mount Brackets Install the hub into a 19-inch rack as illustrated in the following figure: Figure 2-3 Install the Hub into a 19-inch Rack... -

The connectors are labeled IN and OUT respectively for KF-16M. KF-16MS provides IN cascade connector only. • AC Power Socket This socket is used for plugging an AC power cord.

Page 16: Cascading Multiple Hubs
Two cascade connectors are lo- cated on the rear of the hub and labeled IN and OUT respectively for KF-16M. For KF-16MS, only IN cascade connector is provided. Before cascading hubs, make sure the power to the hubs is turned off. -
Page 17: Cascading Four Hubs In One Stack
When cascading more than two hubs, follow the IN-to-OUTdaisy-chain rule as above to cascade all hubs sequentially. Up to four hubs can be cascaded in a stack. Figure 2-6 Cascading Four Hubs in One Stack Only one KF-16MS is needed in one stack if a bridge is required to connect the 10M network and the 100M network in a hub stack. -

3. Making Network Connections 3.1 Dual-speed Twisted-pair Ports Figure 3-1 16 Dual-speed TP Ports The hub provides 16 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. RJ-45 Connectors Each of Port #1 to Port #15 provides one RJ-45 connector, which are implemented as MDI-X jack. -

UTP Cables For connecting to an 10BASE-T Ethernet device, a 2-pair Category 3, 4, or 5 UTP cable can be used. For connecting to a 100BASE-TX Fast Ethernet device, only 2-pair Category 5 UTP cable can be used. Connected Device UTP Cable Used 10BASE-T devices Category 3, 4 or 5... -
Page 20: Connecting To Computers
Connecting to a Computer The RJ-45 connectors labeled 1X to 16X 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 dual-speed NWay adapter. The following figure illustrates the cables used for connecting to different network adapters: Figure 3-3 Connecting to Computers Connecting to 10BASE-T Hubs... -
Page 21: Connecting To A 100Base-Tx Class Ii Hub
Connecting to a 100BASE-TX Hub Since the KF-16M and KF-16MS hubs are designed to comply with IEEE 802.3u Class II repeater specifications, each hub can support one connection to another 100BASE-TX Class II hub only. It is recommended to preserve Port #16 as a uplink port for connecting to another hub (or a hub stack) via a UTP cable. -
Page 22: Hub Stack Connection
3.2 Hub Stack Connection A hub stack composed of multiple hubs (up to four) cascaded together as the instruction in section 2.4 can be treated as a single dual-speed hub which provides up to 64 dual-speed ports. If interconnection of the 10M network and the 100M network is re- quired, one and only one KF-16MS is needed to be installed in a hub stack to bridge the intertraffic between the 10M network and the 100M network. -
