Chapter 1 Product Description The LanEdge FastHub8 and FastHub16 are 10/100 Mbps dual speed hubs for small or medium business applications. With 8 or 16 10/100 Mbps plug-andplay dual speed ports, the hubs support both 10 Mbps and 100 Mbps devices in a single network. The internal switching function provides network connectivity between the two speeds, thereby offering a high level of network flexibility and efficiency. Installation and operation are user-friendly and no configuration is required.
Product Description The Front and Back Panels Figure 1 and Figure 2 show the front and back panels of the hub.
FastHub 8 and FastHub 16 Installation Guide Front Panel LEDs Power. Indicates that the hub is receiving power and is operational. Collision 10M/100M. Each unit has two Collision LEDs: 10M indicates a collision on the 10 Mbps segment, and 100M indicates a collision on the 100 Mbps segment. A collision occurs when two stations within a collision domain attempt to transmit data at the same time. The contending adapters resolve each collision by means of a wait-then-retransmit algorithm.
Product Description Uplink Switch. The slide switch located on the right side of the back panel is for the uplink function. To use Port 8 as an Uplink port, manually set the switch to the “Uplink” position. This eliminates the need for a crossover cable when connecting directly to another hub. Power Connection. For compatibility with electric service in most areas of the world, the hub two-piece power adaptor automatically adjusts to line power range 100~220 VAC and 50~60 Hz.
Chapter 2 Installation The hub does not require software configuration, and is ready to work by simply attaching the cables and power adapter. This chapter provides information and procedures to install the unit. Verifying the Package Content Before you start installation, please check the contents of the package.
Installation Placing the Hub You can wall mount a single LanEdge product, place it on a desktop, or interlock two or more to form a single unit that occupies only one footprint on the desktop. Caution Air vents must not be blocked and must have free access to the room ambient air for cooling. To place your LanEdge product, see the steps that follow: ❑ “To Place a Single LanEdge Product on a Desktop” on page 6. ❑ “To Wall Mount a LanEdge Product” on page 6.
FastHub8 and FastHub16 Installation Guide To Interlock a Group of LanEdge Products on a Desktop The interlocking feature of the LanEdge products makes it easy for you to install the units on a desk or table. You can place the units on top of each other and interlock them to form a stack. A stack can consist of any combination of LanEdge hubs. It is recommended that the heaviest unit be placed as the base (bottom) unit.
Installation 4. Pry off the interlock cap at each corner of the unit. Refer to Figure 4. From the side of the unit, insert the tip of a small straight-slot screwdriver into the opening of the interlock cap. Press down on the screwdriver to pry the cap off. Figure 4 Interlock Cap 5. Place the next unit over the base unit, aligning with the interlock cap and press down on each corner to snap the units together. 6. Repeat steps 4 and 5 until all units are in the assemblage. 7.
FastHub8 and FastHub16 Installation Guide Powering on the Hub Apply power to the FastHub8 and FastHub16 as follows: 1. Plug the power cord into the AC power adapter. 2. Connect the DC cable from the adapter into the hubs’ DC input. 3. Plug the power cord into the correct AC power source for the adapter. 4. Verify that the Power LED lights (see Table 1). If the Power LED is OFF after performing these steps, refer to Chapter 3, “Troubleshooting” on page 11 for further instructions.
Installation Connecting Cables The FastHub8 and FastHub16 have 8 and 16 ports on the back panel, respectively. If the port is connected but the Link/Activity LED is dark (not lit), refer to Chapter 3, “Troubleshooting” on page 11 for further instructions. Connect devices to the hub ports using the following guidelines. Station Connections Connect each station to the hub with a twisted-pair straight cable (10Base-T cable, Category 3, 4, or 5).
Chapter 3 Troubleshooting No Power If the Power LED is OFF, check the following to isolate the problem: ❑ Make sure the AC/DC adapter is properly connected to the power outlet and inserted into the power connection on the hub. ❑ Determine whether or not the outlet is functional by plugging another device into the receptacle. ❑ Power the unit OFF and ON again. If the problem presist, contact Allied Telesyn’s Technical Support.
Troubleshooting 100M LED If the 100M LED for the port does not indicate the correct speed, check the following: ❑ If the port is auto-negotiating, wait 1-3 seconds after the device cable is connected, or power is applied, for the negotiation process to complete. ❑ If Port 8 is used as an “Uplink”, check that the cable length used for an uplink does not exceed 5 meters (16 feet) in an 100 Mbps configuration. ❑ For Ports 1 and 2, check that the speed is correctly set on the DIP switch.
