2. INSTALLATION This section describes the functionalities of the Fast Ethernet Switch’s components and guides how to install it on the desktop. Basic knowledge of networking is assumed. Please read this chapter completely before continuing. 2.
This product also supports store-and-forward forwarding scheme to ensure low latency and high data integrity, eliminates unnecessary traffic and relieves congestion on critical network paths. With an intelligent address recognition algorithm, the switches could recognize up to 1K different MAC address and enables filtering and forwarding at full wire speed. 2.1.

LNK/ACT Green Lit: indicate the link through that port is successfully established. Blink: indicate that the switch is actively sending or receiving data over that port. Power Notice: 1. The device is a power-required device, it means, it will not work till it is powered.
consider using UPS (Uninterrupted Power Supply) for your device. It will prevent you from network data loss or network downtime. 2. In some area, installing a surge suppression device may also help to protect your switch from being damaged by unregulated surge or current to the Switch or the power adapter. 2.2 Installing the Switch This part describes how to install your Fast Ethernet Switch and make connections to it.
Note: Connection to the switch requires UTP Category 5 network cabling with RJ-45 tips. For more information, please see the Cabling Specification in Appendix A. Step5: Supply power to the switch. A. Connect one end of the power cable to the switch. B. Connect the power plug of the power cable to a standard wall outlet. When the switch receives power, the Power LED should remain solid Green.
3. SWITCH OPERATION 3.1 Address Table The 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. 3.2 Learning When one packet comes in from any port, the Switch will record the source address, port no. And the other related information in address table.
3.4 Store-and-Forward Store-and-Forward is one type of packet-forwarding techniques. A Store-and-Forward Ethernet Switching stores the incoming frame in an internal buffer, do the complete error checking before transmission. Therefore, no error packets occurrence, it is the best choice when a network needs efficiency and stability. The Ethernet Switch scans the destination address from the packet-header, searches the routing table provided for the incoming port and forwards the packet, only if required.
connection is established with another network device (usually at Power On or Reset). This is done by detect the modes and speeds at the second of both device is connected and capable of, both 10Base-T and 100Base-TX devices can connect with the port in either Half- or Full-Duplex mode. 1000Base-T can be only connected in Full-duplex mode.
4. 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. Some stations cannot 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. Please power down to refresh the address information. Performance is bad Solution: Check the full duplex status of the Ethernet Switch.
