AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide Overview The AT-FS716L and AT-FS724L Fast Ethernet Switches provide simple, energy efficient, and cost-effective solutions for switching 10 Mbps and 100 Mbps network traffic. The AT-FS716L and AT-FS724L switches feature 16 and 24 10/100Base-TX twisted-pair ports respectively. Each port has an RJ-45 connector and a maximum operating distance of 100m and is capable of Auto-Negotiating speeds of 10 or 100 Mbps at half/full-duplex operation.
Chapter 1: Product Description Key Features The AT-FS716L and AT-FS724L Fast Ethernet switches have the following key features: 16 each RJ-45 10/100Base-TX ports on the AT-FS716L Switch 24 each RJ-45 10/100Base-TX ports on the AT-FS724L Switch ecoFriendly power saving features including: – Auto-power saving mode on a per-port basis when link is down – Auto-adjusts port power output based on cable length when link is up – Low power mode LED ecoFriendly push button – Highly efficient internal Powe
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide Hardware Feature Description The hardware features of the AT-FS716L and AT-FS724L Fast Ethernet switches are described in the following sections: ecoFriendly Power Saving Functions “ecoFriendly Power Saving Functions” “Twisted-Pair Ports” on page 14 “System and Port LEDs” on page 15 “High Efficiency Internal Power Supply” on page 16 The AT-FS716L and AT-FS724L implement the following power saving features.
Chapter 1: Product Description LED ecoFriendly Push Button The LED ecoFriendly push button is located next to the Power LED on the left-hand side of the front panel as illustrated in Figure 3. It enables the LED Low Power Mode (LPM) feature. This mode allows you to conserve power by turning off the port status LEDs when you do not required the LED status indications on the front panel. To toggle the LEDs on or off, press the ecoFriendly button.
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide Maximum Distance Each twisted-pair port has a maximum operating distance of 100 m (328 feet). Type of Cabling For 10 Mbps operation, Category 3 or better 100 ohm shielded or unshielded twisted-pair cabling is required. For 100 Mbps operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted-pair cabling is required. Auto MDI/MDI-X All of the twisted-pair ports on these switches are auto-MDI and IEEE 802.
Chapter 1: Product Description Table 1. System and Port LEDs LED DPX High Efficiency Internal Power Supply State Description Green The port is establishing at full-duplex mode. Blinking Green Collisions are present on the port. OFF The port is establishing at half-duplex mode. The AT-FS716L and AT-FS724L Fast Ethernet Switches are both designed for low power consumption while operating.
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide A Few 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.
Chapter 1: Product Description Duplex Mode Duplex mode refers to how an end-node receives and transmits data. If an end-node can receive or transmit data, but not both simultaneously, it is operating in a half-duplex mode. If an end-node can 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 halfduplex mode.
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide How a switch signals an end-node to stop transmitting data differs depending on the duplex mode of the end-node and switch port. A twisted-pair port operating in half-duplex mode stops an end-node from transmitting data by forcing a collision. A collision on an Ethernet network occurs when two end-nodes attempt to transmit data using the same data link at the same time.
Chapter 1: Product Description Network Topologies This section illustrates two network topologies that you can create with either the AT-FS716L or the AT-FS724L Fast Ethernet switch in the following sections. Both the power workgroup and cascade topologies are described. Power Workgroup Topology The topology shown in Figure 4 is commonly referred to as a power workgroup topology. In this configuration, each workstation, or end-node is connected directly to a port on the switch.
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide Cascade Topology Connecting two similar networking devices together is called “cascading.” Figure 5 illustrates this topology where Port 19 on the AT-FS724L switch is connected to Port 16 on the AT-FS716 switch. Since the ports are configured as auto MDI/MDI-X, a crossover or straight-through Category 5 or better twisted-pair cable can be used in any of the ports.
Chapter 2 Installation This chapter contains the following sections: “Reviewing Safety Precautions” on page 23 “Selecting a Site for the Switch” on page 26 “Planning the Installation” on page 27 “Unpacking the Switch” on page 28 “Installing the Switch on a Table or Desktop” on page 29 “Installing the Switch in a Rack” on page 30 “Wall-Mounting the Switch” on page 32 “Connecting the Ports and Powering On the Switch” on page 36 22
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide Reviewing Safety Precautions Please review the following safety precautions before you begin to install the switch or any of its components.

Chapter 2: Installation Warning Class I Equipment. This equipment must be earthed. The power plug must be connected to a properly wired earth ground socket outlet. An improperly wired socket outlet could place hazardous voltages on accessible metal parts. E6 Caution Pluggable Equipment: The socket outlet shall be installed near the equipment and shall be easily accessible. E7 Caution Air vents: Air vents must not be blocked and must have free access to the room ambient air for cooling.
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the room ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer’s maximum rated ambient temperature (Tmra).
Chapter 2: Installation Selecting a Site for the Switch Observe the following requirements when choosing a site for the AT-FS716L or AT-FS724L Fast Ethernet Switches: If you plan to install the switch in an equipment rack, be sure that the rack is safely secured and that it will not tip over. Devices in a rack should be installed starting at the bottom, with the heavier devices near the bottom of the rack. If you are installing the switch on a table, be sure that the table is level and secure.
AT-FS716L & AT-FS724L Fast Ethernet Switch Installation Guide Planning the Installation Be sure to observe the following guidelines when planning the installation of your switch. The end-nodes connected to the twisted-pair port can be operated at either 10 Mbps or 100 Mbps and half- or full-duplex mode. The end-node connected to a port on the switch can be a network adapter card, repeater, router, hub, or another switch. Table 2 contains the cabling specifications for the twisted-pair ports.
Chapter 2: Installation Unpacking the Switch To unpack an AT-FS716L or an AT-FS724L switch, perform the following procedure: 1. Remove all components from the shipping package.
