Chapter 2 Network Planning An Ethernet or Fast Ethernet switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
Some typical topologies are described below. Collapsed The AT-8324SX switch is an excellent choice for mixed Ethernet and Fast Backbone Ethernet installations where significant growth is expected in the near future.
With up to 100 ports in a stack (i.e., 100 distinct segments), the Closet AT-8324SX switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10Base-T/100Base-TX ports on the AT-8324SX stack are providing 100 Mbps connectivity for up to 100 segments through Ethernet hubs.
Fiber optic technology allows for longer cabling than any other media Connections with type (up to 2 kilometers/1.24 miles for 100 Mbps fiber at full-duplex). The AT-8324SX switch can serve as a collapsed backbone, providing direct Fiber Cable connectivity for a widespread LAN. The 100 Mbps fiber module can be used to interconnect remote Fast Ethernet segments, while the Gigabit fiber module can be used to interconnect buildings in a campus setting.
VLAN. When VLANs cross separate switches, it is therefore better to use VLAN tagging. This allows you to assign multiple VLAN groups to the trunk ports (that is, tagged ports) connecting different switches. AT-8324SX Fast Ethernet Switch 10BASE-T / 100BASE-TX SWITCH FAST ETHERNET...
Network Planning Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for Ethernet and Fast Ethernet. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
AT-8324SX Installation Guide The AT-B15/LX has one 1000Base-LX fiber optic port with a SC connector. This module operates at 1 Gbps and supports auto- negotiation for duplex mode (half- or full-duplex) and flow control. Refer to Table 3 for the cabling specifications for this module.
# For network applications that actually require routing (such as when interconnecting dissimilar network types or distinct VLANs), you may have to attach the AT-8324SX switches directly to a router or Layer 3 switch.
Chapter 3 Installing the Stack This chapter contains instructions on how to install the AT-8324SX switch. Selecting a Site AT-8324SX switches can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location.
Installing the Stack Reviewing Safety Precautions Review the following safety precautions before you begin to install the switch. Refer to Appendix C for translated safety statements in your language. The first two safety precautions apply only if you install an expansion module in the switch.
AT-8324SX Installation Guide Equipment Checklist After unpacking the AT-8324SX switch, check the contents to be sure you have received all the components. Then, before beginning the installation, be sure you have all other necessary installation equipment. Package Contents # One AT-8324SX Fast Ethernet Switch...
Installing the Stack Mounting An AT-8324SX switch can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Note If you have purchased an expansion module or a stacking module for the switch, install the module now by following the instructions included with the optional package.

AT-8324SX Installation Guide 2. Mount the device in the rack, using four rack-mounting screws (not provided). Figure 12 Installing the Switch in a Rack 3. If installing a single switch only, refer to Connecting to a Power Source on page 44.
Installing the Stack Desktop or Shelf To rack mount devices, perform the following procedure: Mounting 1. Attach the four adhesive feet to the bottom of the first switch. Figure 13 Attaching the Adhesive Feet 2. Set the device on a flat surface near an AC power source, making sure there are at least 5 centimeters (2 inches) of space on all sides for proper air flow.
Note A stacking cable is included with the AT-BSTACK1 Stacking Module. Caution Do Not stack AT-8324SX switches with other devices. Doing so may damage the switch. To stack the devices, perform the following procedure: 1. Locate the stack connectors labeled "UP" and "DOWN" on the stack modules (see Figure 14).
Installing the Stack Connecting to a Power Source Note It is recommended that the switches be stacked before being connected to a power source. However, a device can be added to the top or bottom of a stack that is ON and operating without first powering down the stack.
Chapter 4 Making Network Connections The AT-8324SX switch is designed to interconnect multiple segments, or collision domains. It may be connected to 10 and 100 Mbps network cards in PCs and servers, as well as to Ethernet and Fast Ethernet hubs, switches or routers.
Switches Figure 16 Making Twisted Pair Connections 2. If the device is a network card and the AT-8324SX switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet (see Wiring Closet Connections on page 47).
Make sure each twisted pair cable does not exceed 100 meters (328 feet) in length. 3. As each connection is made, the Link LED (on the AT-8324SX switch) corresponding to each port will be green to indicate that the connection is valid.
Making Network Connections AT-B15/SX and AT-B15/LX (1000Base, SX and LX) Expansion Modules If an AT-B15/SX or AT-B15/LX Expansion Module is present, its Gigabit port may be used for a backbone connection between switches or for connecting a high-speed server. Each 1000Base-SX device requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at both ends.
AT-8324SX Installation Guide AT-B17 (100Base-FX) Expansion Module If an AT-B17 Expansion Module is present, its fiber ports may be used for backbone and longer distance connections. This expansion module requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at both ends. For SC fiber ports, connect one end of the cable to the SC connector on the expansion module and the other end to the SC connector on the other device.
Chapter 5 Troubleshooting This chapter contains troubleshooting information. Diagnosing Switch Indicators Table 6 Troubleshooting Chart Symptom Action Power LED is OFF - Internal or redundant power supply has failed or is disconnected. - Check connectors between the switch, the power cord, the wall outlet, and the RPU, if you are using one.
Troubleshooting Power and Cooling Problems If the Power LED does not turn ON when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit powers OFF after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the right side of the unit are unobstructed and running prior...
AT-8324SX Installation Guide Installation Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.
Troubleshooting In-Band Access You can access the management agent on the switch from anywhere within the attached network using Telnet, a Web browser, or other network mangement software. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection.
Cables Twisted Pair Cable and Pin Assignments Caution Do not plug a phone jack connector into any RJ-45 port. Use only twisted pair cables with RJ-45 connectors that conform with FCC standards. For 10Base-T/100Base-TX connections, a twisted pair cable must have two pairs of wires.
