Chapter 1 Overview This chapter contains the follows sections: “Features” on page 16 “Port Descriptions” on page 17 “LEDs” on page 19 “Power Supply” on page 20 “Power over Ethernet” on page 21 “Ethernet Switching Basics” on page 23 “Network Topologies” on page 26 15
Chapter 1: Overview Features The AT-FS708/POE Fast Ethernet switch is an unmanaged switch with the following features: Eight Auto-Negotiating 10/100Base-T twisted pair ports with Power over Ethernet (PoE) capability One small form-factor pluggable (SFP) port to use as an uplink port System and port LEDs Power over Ethernet, IEEE 802.3af The AT-FS708/POE switch can be used on a desktop, mounted to a wall, or mounted in a rack.
AT-FS708/POE Fast Ethernet Switch Installation Guide Port Descriptions The following sections describe the types of ports on the AT-FS708/POE Fast Ethernet switch: Twisted Pair Ports “Twisted Pair Ports,” next “SFP Port” on page 18 The AT-FS708/POE Fast Ethernet switch features eight 10/100Base-T twisted pair ports. The twisted pair ports feature 8-pin RJ-45 connectors. For the port pinouts, refer to “RJ-45 Twisted Pair Port Connectors and Pinouts” on page 51.
Chapter 1: Overview ports. SFP Port The AT-FS708/POE switch has one SFP port that can accommodate an optional Small Form-factor Pluggable (SFP) transceiver. The SFP transceiver is a fast and easy way for you to add an 1000 Mbps fiber optic uplink port to your Fast Ethernet switch. You can use the SFP to extend the distance of your network, build a high-speed backbone network between switches, or connect additional end nodes to the network, such as high-speed servers.
AT-FS708/POE Fast Ethernet Switch Installation Guide LEDs The system and port LEDs on the front panel of the AT-FS708/POE Fast Ethernet switch switch display the switch and its port status information. Table 2 describes the system LED. Table 2. System LED LED PWR State Description Green The switch is powered ON and operating normally. OFF The switch has no power. Each twisted pair port has two LEDs, as described in Table 3. Table 3.
Chapter 1: Overview Power Supply The AT-FS708/POE Fast Ethernet switch has an internal power supply with a single AC power supply socket on the back panel which features autoswitch AC inputs. To power the switch on or off, connect or disconnect the power cord provided with the switch. Note For the power requirements, refer to “Power Specifications” on page 55.
AT-FS708/POE Fast Ethernet Switch Installation Guide Power over Ethernet The twisted pair ports on the AT-FS708/POE Fast Ethernet switch feature Power over Ethernet (PoE). PoE is a mechanism for supplying power to network devices over the same twisted pair cables used to carry network traffic. This feature can simplify network installation and maintenance by allowing you to use the switch as a central power source for other network devices.
Chapter 1: Overview Implementation A standard Ethernet twisted pair cable contains four pairs of strands for a total of eight strands. 10/100 Mbps network traffic requires only four strands, leaving four strands in the cable unused. The strands that carry the network traffic are 1, 2, 3, and 6, and the spare strands are 4, 5, 7, and 8. The IEEE 802.3af standard, which is the standard for PoE, describes two modes for delivering power to the powered device over twisted pair cabling.
AT-FS708/POE Fast Ethernet Switch Installation Guide Ethernet Switching Basics An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
Chapter 1: Overview end node can receive or transmit data, but not both simultaneously, the end node is operating in what is referred to as half-duplex mode. If an end node can both receive and transmit data simultaneously, the end node is said to be operating in full-duplex mode. Naturally, an end node capable of operating in full-duplex can handle data much faster than an end node that can only operate in half-duplex mode.
AT-FS708/POE Fast Ethernet Switch Installation Guide sending data. This can occur under several circumstances. For example, if two end nodes are operating at different speeds, the switch, while transferring data between the end nodes, might need to instruct the faster end node to stop transmitting data to allow the slower end node to catch up. An example of this would be when a server operating at 100 Mbps is sending data to a workstation operating at only 10 Mbps.
Chapter 1: Overview Network Topologies This section illustrates two network topologies that you can create with the AT-FS708/POE Fast Ethernet switch: a power workgroup and collapsed backbone. Both types of topologies are described below. Power Workgroup Topology The topology shown in Figure 3 is commonly referred to as a power workgroup topology. Each workstation or end node is connected directly to a port on the switch.
AT-FS708/POE Fast Ethernet Switch Installation Guide In the topology shown in Figure 4, an AT-FS708/POE Fast Ethernet switch is connected to an AT-9424T/SP and a number of AT-FS705PD powered devices in different destinations. Using the AT-FS708/POE Fast Ethernet switch in combination with the AT-FS705PD powered devices, you can generate a complete POE Security network at a fraction of the cost.
