1. INTRODUCTION 1.1 Checklist Check the contents of your package for following parts: GSD-1020 User's manual Power cord If any of these pieces are missing or damaged, please contact your dealer immediately, if possible, retain the carton including the original packing material, and use them against to repack the product in case there is a need to return it to us for repair. 1.
2. HARDWARE DESCRIPTION This section describes the hardware features of the Giga Switch. For easier management and control of the switch, familiarize yourself with its display indicators, and ports. Front panel illustrations in this chapter display the unit LED indicators. Before connecting any network device to the Switch, read this chapter carefully. 2.1 Front Panel The unit front panel provides a simple interface monitoring the switching. It includes a power indicator for each port.
1000Base-T LED Color Function ACT Green Lit: indicate that the switch is actively sending or receiving data over that port. 1000/100 Green Lit: indicate that connection made through the corresponding port is running at 1000Mbps. Orange Lit: indicate that connection made through the corresponding port is running at 100Mbps. FDX Green Lit: indicate that the connection made through the corresponding port is running in Full Duplex mode.
3. INSTALLATION 3.1 Before start up Before your installation, please refer to the followings for your cabling: 100Base-TX All 100Base-TX ports come with auto-negotiation capability. They automatically support 100Base-TX and 10Base-T networks. Users only need to plug a working network device into one of the 100Base-TX ports, then turn on the Switch. The port will automatically runs in 10Mbps, 20Mbps, 100Mbps or 200Mbps after the negotiation with the connected device.
Figure 3. End node, Hub or Switch connection Notice: Cable distance for Switch The cable distance between Ethernet Switch and hub/PC should not exceed 100 meter for UTP/STP cable. Make sure the wiring is correct It can be used Category 3/4/5 cable in 10 Mbps operation. To reliably operate your network at 100Mbps and 1000Mbps, you must use an Unshielded Twisted-Pair (UTP) Category 5 cable, or better Data Grade cabling. While a Category 3 or 4 cable may initially seem to work, it will soon cause data loss.
4. SWITCH OPERATION Address Table The Giga Switch is implemented with an address table. This address table composed of many entries. Each entry is used to store the address information of some node in network, including MAC address, port no, etc. This information comes from the learning process of Ethernet Switch. Learning When one packet comes in from any port, the Giga Switch will record the source address, port no. and the other related information in address table.
5. TROUBLESHOOTING This chapter contains information to help you solve problems. If Giga Switch is not functioning properly, make sure the Ethernet Switch was set up according to instructions in this manual. The Link LED is not lit Solution: Check the cable connection and remove duplex mode of the Giga Switch Some stations can not talk to other stations located on The other port Solution: The address table may contain older information than of the address table of that node.
