Operating Environment These Dual Speed Hubs must be installed and operated within the limits of specified operating temperature and humidity (see previous section under Specifications). Do not place objects on top of the unit. Do not obstruct any vents at the sides of the unit. Do not position the hub near any heating source such as heater, radiator, or direct exposure to sun. Prevent entering of water and moisture into the unit. If necessary, use dehumidifier to reduce humidity. 2. Connecting to network devices Connect one end of the network cable to any of the RJ45 ports on the front panel, and connect the other end of the network cable to the RJ45 port of the network device. The network cables must comply with EIA/TIA 568 specifications and Category 5 standard for 100Mbps data rate or minimum Category 3 for 10Mbps data rate. Maximum length between the hub and any network devices is 100 meters (300ft). Once the network cable is connected on both ends and the attached network devices are powered on, the green Link Status LED should be lit. If the connected network devices are running at 100Mbps, the green Speed LED (100M) should also be lit. 3. Uplink to Another Hub Use the uplink port (the last port) to connect to another hub as illustrated in Figure 5-2. Connecting cable must comply with EIA/TIA 568 specifications and Category 5 (100Mbps) standards to connect the hubs. The Uplink port of the Dual-Speed hub supports Auto-Sensing function which will automatically sense the speed of the connected hub and operates at either 100Mbps or 10Mbps speed. If the connected hub is another Dual-Speed hub or 100Base-TX hub, the transmission speed between the two hubs will be set at 100Mbps and the green Speed (100M) LED should be lit. The maximum length of the cable should not exceed 5 meters (15ft) when connecting two hubs running at 100Mbps and 100 meters (300ft) when connecting two hubs running at 10Mbps.

Stacking Hubs Together These Dual Speed Hubs provide two stacking ports. Users may connect two hubs using the supplied stacking cable. Connect one end of the stacking cable to the IN stacking connector of the hub and the other end of the stacking cable to another hub OUT stacking connector. You may stack up to 10 hubs. The hubs cascaded together through stacking ports are in one collision domain and therefore considered as one logical dual speed hub. When you have two or more hubs stacked together, only one hub s internal switch is active, the others are inactive. Such design will eliminate a Loop in the network that might cause the whole network to malfunction.
