13 AT-FS708LE Fast Ethernet Switch Overview The AT-FS708LE unit is a 10Base-T/100Base-TX Fast Ethernet Switch. The unit provides you with a simple, cost-effective solution for Ethernet switching between end-nodes operating at either 10 or 100 Mbps. Figure 1 and Figure 2 show the front and back panel...

14 Figure 2 Back Panel Key Features The AT-FS708LE Ethernet Switch has the following features: ❑ LEDs for unit and port status ❑ 8 Auto-Negotiating 10/100 Mbps twisted pair ports with RJ-45 connectors ❑ Auto MDI/MDI-X on all ports ❑ IEEE 802.3 and IEEE 802.3u compliant ❑ Store and forward switching ...

AT-FS708LE Installation Guide 15 Status LEDs Refer to Table 1 for a description of the device LEDs. Table 1 LED Functions LEDs Color Description PWR Green Indicates the switch is receiving power. 100M Green OFF Indicates the port is operating at 100 Mbps. Indicates the port is operating at 10 Mbps. ...

18 The AT-FS708LE supports TX Flow Control only. This means a PAUSE packet will be transmitted to the end-node connection if it receives data faster than it can switch the packets. The AT-FS708LE does not support RX Flow Control, however, and it will not respond to PAUSE packets sent to it by an end...

AT-FS708LE Installation Guide 19 port on the switch and the end-node are operating at the same speed and that they are communicating at the highest possible common speed of the devices. Duplex Mode Duplex mode refers to the way an end-node sends and receives data on the network. An end-node can oper...

22 Network Topologies The AT-FS708LE switch can be used in a variety of network topologies, such as a standalone or cascade. Both topologies are described below. Standalone Topology Figure 3 illustrates the standalone topology where each end-node is directly connected directly to a 10/100Base-TX por...

AT-FS708LE Installation Guide 23 Cascade Topology Figure 4 illustrates the cascade topology where Port 1 on the AT-FS708LE switch is connected to Port 8 on the AT-FS716E switch. Since Port 1 is wired as auto MDI/MDI-X, a crossover or straight-through Category 5 or better twisted pair cable can be us...

24 Note Cascading switches, as shown in Figure 4, can result in data loss between switches if the data rate exceeds 100 Mbps. Symptoms may include inability of certain workstations to “Log-On” to a server or unusually slow data transfer rates between workstations or servers. Planning the Installatio...
