11 Introduction Congratulations on your purchase of this rackmount stackable dual-speed hub. Migrating from traditional 10Mbps Ethernet to 100Mbps Fast Ethernet is now simple and affordable with these dual-speed hubs. These high performance 16-port, 24-Port, 32-port 10/100Mbps stackable dualspeed hubs are equipped with 16, 24, 32 RJ45 dual-speed ports, one uplink port and one internal 2-port switch. Typically a dual-speed hub has two independent internal network segments: 10Mbps segment and 100Mbps segment.
Dual-Speed hub with internal switching function automatically switches data traffic between devices running at different speed, which allows communications between ports running at 10Mbps and ports running at 100Mbps. Dual-Speed hub with internal switching function can save money by eliminate the need to purchase expensive Switches for users with mixed speed network environment.
22 Features & Specifications (1) Features Consists of one internal 10Mbps Ethernet segment and one internal 100Mbps Fast Ethernet segment. Supports Auto-Sensing RJ45 ports which automatically sense and select optimum speed and route data traffic to corresponding internal segments. Built-in Uplink selection for the last port to connect with regular straight-through cable to another hub. Network Utilization LEDs provides simple reading on hub s traffic status.

55 Installation 1. 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.

5. Connecting the power Connect the power cord to the power socket on the rear panel of the unit. Connect the power cord to the power outlet and turn on power switch. The green Power LED on the front panel should be lit.
66 Trouble-shooting 1. Power LED is not lit Check if the power cord is properly connected to the power outlet and the hub. Make sure the power switch on the hub is turned ON. . 2. Link Status LED is not lit Check the power switch of the network devices attached to the hub, make sure they are turned ON. Check the network cable, make sure it is properly connected to the hub and the network device. Check the network cable, make sure the cable complies with EIA/TIA 568 specification.
