Chapter 1 Overview The AT-FS724L is Fast Ethernet switch that provides simple, cost-effective solutions for switching between 10 Mbps and 100 Mbps. The AT-FS724L switch features 24 10/100Base-TX twisted pair ports. Each twisted pair port has a RJ-45 connector and a maximum operating distance of 100 meters (328 feet). These ports are capable of Auto-Negotiating at 10 or 100 Mbps and feature half- and full-duplex operation.
Overview Key Features The AT-FS724L switch has the following key features: 24 10/100Base-TX ports System and port LEDs Auto MDI/MDI-X on all ports Auto-Negotiation on all ports (IEEE 802.3u-compliant) Store and forward switching mode Backpressure and flow control (IEEE 802.
AT-FS724L Fast Ethernet Switch Installation Guide Status LEDs Table 2 lists the status LEDs for the AT-FS724L switch. Table 2 Status LEDs LED Color Description POWER Green Power is applied to the switch. OFF No power is applied to the switch. Green A valid link has been established on the port. Blinking The port is transmitting data. OFF A link has not been detected on the port. Green The port is operating at 100 Mbps. OFF The port is operating at 10 Mbps.
Overview Duplex Mode Duplex mode refers to the way an end-node sends and receives data on the network. An end-node can operated in either half- or full-duplex mode depending on its capabilities. An end-node that is operating in half-duplex mode can either send data or receive data, but it cannot do both at the same time. An end-node that is operating in full-duplex mode can send and receive data simultaneously.
AT-FS724L Fast Ethernet Switch Installation Guide the port on the switch automatically configures itself as MDI-X. This feature allows you to use either a crossover cable or a straight-through cable when connecting a device to a twisted pair port. MAC Address Table The heart of an Ethernet switch is the Media Access Control (MAC) address table. Every device that you attach to an Ethernet network has a MAC address. This address is assigned to the device by the device’s manufacturer.
Overview This timer will delete a MAC address from the table if it does not see a frame from the end-node with the address on any port after five minutes (300 seconds). The aging timer also helps to ensure that the table is correct should an end-node be moved from one port on the switch to another port. Store and Forward These Fast Ethernet Switches use store and forward as the method for receiving and transmitting frames.
AT-FS724L Fast Ethernet Switch Installation Guide Internal Power Supply The AT-FS724L uses a universal internal switching power supply operating at 100-120/200-240V AC. The frequencies are 50/60 Hz, 0.5A at all input voltage +/-3%. Allied Telesyn ships power cords with these units to the U.S., Continental Europe, and the U.K. The switches require input of 100-120 or 200-240V AC. The AT-FS724L switch has a maximum power consumption of 15W.
Overview Network Topologies The AT-FS724L switch can be used in a variety of network topologies, such as a power workgroup or cascade. Both topologies are described below. Power Workgroup Topology A power workgroup topology, shown in Figure 2, allows each end-node to directly connect to a 10/100Base-TX port on an AT-FS724L switch. This gives each end-node a dedicated 10 Mbps or 100 Mbps link.
AT-FS724L Fast Ethernet Switch Installation Guide Cascade Topology Connecting two similar networking devices together is called ‘cascading’. Figure 3 illustrates this topology where Port 24 on the AT-FS724L switch is connected to Port 8 on the AT-FS716 switch. Since Port 24 is wired as auto MDI/MDI-X, a crossover or straight-through Category 5 or better twisted pair cable can be used.
Chapter 2 Installation Verifying the Package Contents Make sure the following items are included in your package. If any item is missing or damaged, contact your Allied Telesyn sales representative for assistance.
Installation 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 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. ❑ Refer to Table 3 for the cabling specifications for the twisted pair ports.
AT-FS724L Fast Ethernet Switch Installation Guide Reviewing Safety Guidelines Please review the following safety guidelines before you begin to install the switch. Warning Electrical Shock Hazard: To prevent electrical shock, do not remove the cover. There are no user-serviceable parts inside. The unit contains hazardous voltages and should only be opened by a trained and qualified technician. 5 Warning Lightning Danger: Do not work on equipment or cables during periods of lightning activity.
Installation Installing the Switch on a Table or Desktop If you are rackmounting an AT-FS724L switch, refer to “Rackmounting the Switch” on page 15. To install the switch on a table or desktop, perform the following procedure: 1. Remove all equipment from the packaging and store the packing material in a safe place. In the event a problem occurs and you need to return the unit, please use as much of the original shipping material as possible. 2. Attach the four protective feet to the bottom of the unit.
AT-FS724L Fast Ethernet Switch Installation Guide Rackmounting the Switch The AT-FS724L switch can be used on a desktop or installed in a rack. For desktop installation, refer to “Installing the Switch on a Table or Desktop” on page 14. To install an AT-FS724L in a rack, perform the following procedure: 1. If attached, remove the four protective feet from the bottom of the switch as shown in Figure 5. Figure 5 Removing the Rubber Feet 2. Remove the data cables and power cord from the switch. 3.
Installation 4. Secure the switch to the rack using 2 screws (not provided) for each side as shown in Figure 7. Figure 7 Installing the Switch to the Rack 5. Apply power to the switch by plugging one end of the power cord to the power receptacle and the other end to a power outlet. Verify that the POWER LED is green. If the LED is OFF, refer to “Troubleshooting” on page 19. Note The switch performs a self-diagnostic test upon power up. This takes about 20 seconds to complete. 6.
AT-FS724L Fast Ethernet Switch Installation Guide Warranty Registration When you finish installing the product, you should register you product by completing the enclosed warranty card and sending it in.
Chapter 3 Troubleshooting Follow the guidelines below to test and troubleshoot the installation in the event a problem occurs. If the POWER LED is OFF, do the following: For an external power supply, check to be sure that the power adapter is securely connected to a power outlet and that the power adapter cable is securely connected to the back of the switch.
