Introduction

16/24 Port 100/10M Dual-Speed Hub is designed to allow easy migration and integration between 100Mbps Fast Ethernet and 10Mbps Ethernet. It means 100Mbps and 10Mbps users can communicate in the same network environment. It also offers the simplest way to upgrade your network so that you can connect all of your Fast Ethernet and Ethernet hosts to any hub in the series, without any rewiring requirement when a host is upgraded from 10Mbps to 100Mbps.

16/24 Port 100/10M Dual-Speed Hub supports one optional 100BASE-FX Fiber Optic Module (ST/SC-type) that can deliver a low cost yet high speed data link over fiber, allowing you to expand your networks further than ever before. The optional Fiber Optic Module can exceed the 100-meter limitations of Cat 5 UTP/STP cables, providing greater security and reliability.

The Dual-Speed Hub can be stacked up to 3 units for a total port count of 48 (or 72) connectors for workstations or servers.

n Powerful Performance

As your network grows, you need more bandwidth to stay productive and competitive. Whether you are building a new network or expanding an existing one, the Dual-Speed Hub gives you more power with the ease of plug & play. A full 100Mbps link can be provided to all devices on the LAN if required.

n Dual-Speed Hub

The Dual-Speed Hub has built-in bridge module, thereby providing 100Mbps and 10Mbps users transparent access to the same network, even though the 100Mbps and 10Mbps segments are separated.

n Expansion bridge port function

The Dual-Speed Hub with the internal switching function can be Auto-configured either Master mode or Slave mode. The master mode occurs when a stack in port isnt connected on the rear panel. The slave mode occurs when a stack in port is connected on the rear panel. Therefore, the Dual-Speed Hub changes to either Master mode with one expansion bridge port ( # 1 port ) or slave mode with two expansion bridge ports ( # 1, 9 ports for 16 Port Dual-Speed Hub ; # 1, 13 ports for 24 Port Dual-Speed Hub ) automatically depends on stack configuration.

n Optional Fiber Optic Module

The Dual-Speed Hub includes a module slot which can be configured with fiber module to expand the network size and to connect within a fiber cabled environment. With this optional fiber optic module installed, data transmissions are not affected by electrical interference and the distance of the link can be 208 meters to another hub or 412 meters (2000 meters in FDX mode) to a switching hub.

Utilization These LEDs display the utilization percentages in 5%,

15%, 25%, 35%, and 55%.

100M The LED is ON when the linking status is at 100Mbps. Partition The LED is ON when a port on the Hub is malfunc-

tioning. The faulty ports are automatically isolated by the Hub. When the port recovers, however, the Partition LED will return to the normal status.

Quick Installation

Step 1 Unpacking the package Step 2 Check package items Step 3 Place the Hub on a table or the mounting rack Step 4 Plug the UTP/STP cable to both connected devices:

the Hub and the workstations/servers

Step 5 Attach the power cord to the Hub and then plug it into a

power outlet. We recommend the use of a surge suppressor.

Rack-Mount Installation

16/24-Port 100/10M Dual-Speed Hub comes with two brackets and six screws for rack mounting at standard 19 mounting rack. Before you install the Hub, please make sure your operating environment, including power adapter, sufficient space, and proximity to the other network devices that are to be connected.

Step 1 Choose a suitable location for mounting the hub. Step 2 Insert screws into each hole on the bracket and anchor to

each side of the Hub, as shown in Figure 3.1.

Connecting to an Additional Hub

16/24-Port 100/10M Dual-Speed Hub can be connected to another Dual-Speed Hub, or other Hubs.

Note:When the Uplink port is used, the port #1 will be unavailable.

♦♦

♦ Cascaded via an Uplink Port

Step 3 Align the Hub to the rack, and secure it with the screws.

Make sure you slide the Hub down until the screws are securely fixed to the Hub, as shown in Figure 3.2.

Hub-to-Hub Uplink

You can link two Hubs or Hub stacks to each other using any of the twisted-pair ports or the Uplink port. Ordinary twisted-pair ports require crossover twisted-pair cables; linking one ordinary twisted-pair port and the Uplink port requires an ordinary straight-through twisted-pair cable. Expansion bridge port supports 100BASE-TX ( Uplink Port ) distance extension up to 100 meters, and 100BASE-FX ( Fiber Port ) distance extension up to 2km in FDX mode.

When connecting two Hubs or Hub stacks in this fashion, due to the increased speed in Fast Ethernet and adherence to the EIA/TIA 568 wiring rules, the maximum distance between any two end-stations in a collision domain is limited to 205 meters. In contrast, the maximum 10BASE-T Ethernet collision domain can be up to 500 meters.

The following table describes different methods of linking Hubs (or Hub stacks):

♦♦

♦ Stacked via Stack Ports

In a stack, 16/24-Port 100/10M Dual-Speed Hub can build up to 48 ( or 72 ) nodes, as shown in Figure 3.4.

Plug the stacking cable into the in port of the top hub and into the out port of the next hub, then repeat this step for each hub in the stack. The link is starting from the in port of the top hub and ending at the out port of the last hub.

Hub to End-Station Connection

After installing the Dual-Speed Hub, it can support up to 16 (or 24) endstation connections. Fast Ethernet connections require a Category 5 UTP/ STP cable. The cable can be up to 100 meters long.

Each Ethernet connection requires a Category 3 or better UTP cable. In order to make an easier transition to 100Mbps for all nodes, we recommend you install Category 5 cable for all connections.

You can connect any combination of PCs, servers, and other network devices to the twisted-pair ports. Please use straight-through twisted-pair cables, dont use crossover cables. The following figure illustrates the pin assignments for a straight-through cable:

Troubleshooting

Symptom Solution

Power indicator does not light up (green) after power on.

Step 1. Check the power cord by

plugging into another device and see if it is functioning properly.

Step 2. If these measures fail to

resolve the problem, have the power supply replaced by your supplier.

The LEDs show off after cable is connected.

Step 1. Make sure you are connected to the Hub. Step 2. Verify that the other end of

the UTP/STP cable is connected to the Hub which

is powered on and on-line. Step 3. Check the UTP/STP cable is connected to RJ-45 port not the Uplink port.
