Chapter 1 Product Description The AT-FH708E Mini Hub is an 8-port 10/100Mbps dual speed hub that offers a cost-effective solution to today’s growing need of network speed integration. With eight 10/100Mbps plug-and-play dual speed ports equipped in its compact body, it is possible to achieve the coexistence of 10Mbps and 100Mbps devices in a single network now and step to 100Mbps network in the future.
Package Contents Package Contents The package should include the following items: ❑ One 8-port Dual Speed Mini Hub ❑ One power adapter ❑ This Installation Guide If any item is missing, please contact your dealer immediately. Front Panel The front panel consists of the following: ❑ LEDs ❑ Uplink Switch (port 8) The LEDs help monitor the hub’s operating status and overall network performance. See Table 1 for further information concerning the LEDs.

Chapter 2 Installation Installing the Mini Hub 1. Place the Hub on a smooth and horizontal surface. 2. Establish network connection by plugging one end of the Category 5 UTP/STP cable RJ45 connector into the hub port, the other end to the Ethernet/Fast Ethernet adapter installed in the workstation computers. 3. If necessary, adjust port speed by setting the DIP switches before connecting network devices. 4. Connect each device by repeating Step 2 and 3. 5. Make sure that each device is connected properly.
Application Application The hub can be deployed where 10Mbps and 100Mbps network devices coexist and need to be integrated. Figure 4 illustrates a sample application.

Chapter 3 Troubleshooting This chapter describes the procedures to test and troubleshoot the hub. Connectivity Testing In the following procedure, you will test each port for a valid connection and to confirm the correct operation of the network. 1. Start with Ports 1 and 2. Connect these two ports of a single hub to two nodes or workstations and turn on the hub’s power supply. 2. Make sure the Link/Activity and other LEDs of both hub ports are lit. 3.
Problem Solving Problem Solving Is the unit receiving power? Check the POWER LED on the front of the hub. This green LED should be lit. If the power LED is not on: 1. Check the back of the unit. Make sure the power cord is attached securely. 2. Check the AC power adapter. Make sure the power adapter is plugged into a functioning wall outlet and that it is properly inserted into the hub’s power connector on the back of the unit.
AT-FH708E Hub Installation Guide 4. Problem 4: There is data loss between the hub and one of the attached network nodes. ❑ Solution 4: — Make sure that the cable length between the hub and the connected network device is no greater than 100 meters. — Make sure you are using Category 5 cable.
Appendix A Hub Specifications Physical Characteristics Chassis Dimensions: 6.0 in. (153 mm) (L) x 6.6 in. (169 mm) (W) x 1.8 in. (3 mm) (H) Weight: 2 lbs. 12 oz (1.25 kg.) Operating temperatures: 0° to 40° C (32o F to 104o F) Storage temperatures: -20° to 70° C (-4° F to 158° F) Relative humidity: 10% to 90% (operating) 5% to 90% (storage) Operating altitude: Up to 10,000 ft (3,048 m) Standard: IEEE 802.3 10Base-T Ethernet IEEE 802.
Cabling Specifications Cabling Specifications Category 5 UTP/STP for 100 Mbps; Category 3, 4, or 5 UTP for 10 Mbps Maximum of 100 meters between hub and network node Electrical Specifications Power: External power supply with 100 to 120 VAC or 200 to 240 VAC, 50/60 Hz input. UTP (RJ45) Connector Figure 5 shows an RJ45 connector. For a 100Base-TX link between switches, —any two Medium Attachment Units (MAUs)—you need a crossover cable.
AT-FH708E Hub Installation Guide 100Base-TX Cable There are various grades of voice-quality and data-quality cables available. These can appear to be similar externally, although their highspeed data transmission characteristics are radically different. The identification problem is made worse by some suppliers selling voice-quality cables as data-quality cables. If voice-quality cables are used in a 100Base-TX network system, data movement may be slow, collision-prone or non-existent.
