Chapter 1 Overview The AT-8324SX Fast Ethernet Switch is a stackable switch with 24 10Base-T/100Base-TX ports, plus two slots for optional 100Base-FX, 1000Base-SX, and 1000Base-LX expansion modules. One of these slots can also be used for the optional AT-BSTACK1 Stacking Module that allows you attach up to four switches to a 4 Gbps high-speed backplane. There is also an expansion slot for the AT-BMGMT module, an SNMP-based network management module.
Overview About the AT-8324SX Switch Figure 1 illustrates the front panel of the switch. Expansion Module Indicators 10/100 Mbps RJ-45 Ports Port Status Indicators System Indicators Mode Selection Figure 1 AT-8324SX Front Panel Figure 2 illustrates the rear panel.
AT-8324SX Installation Guide Switch Architecture The AT-8324SX switch employs a high-speed switching fabric. This design allows for simultaneous transport of multiple packets at low latency on all ports. It also uses store-and-forward switching to ensure maximum data integrity. In this mode, the entire packet must be received into a port buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.
Overview How to Use this Guide Read Chapters 1 through 4 before installing the AT-8324SX switch. You can also read the AT-S29 Software Management User’s Guide to learn how to manage your network. This guide is available from the Allied Telesyn web site.
AT-8324SX Installation Guide Description of Hardware 10Base-T/ 100Base-TX Ports These ports are dual-speed RJ-45 ports with built-in wiring crossovers (MDI-X). Workstations and servers can be connected to these ports with straight-through cable. When connecting to another switch or a hub, you can connect to a port on the attached device that does not have built-in wiring crossovers (MDI) or use crossover cabling (see Appendix A for a pin-out description of crossover cable).
Overview Table 1 Port and System Status LEDs (Continued) LED Condition Status FLOW ON The port Mode LEDs are indicating the status of flow control for each port. DUP ON The port Mode LEDs are indicating the duplex mode of each port. ACT ON The port Mode LEDs are indicating the status of traffic on each port. STATUS ON A module is installed in the slot. ACT Flashing Traffic is passing through the port. Mode Select Module Ports 1. Use the Mode Select button to select LED display mode.
AT-8324SX Installation Guide The module provides a wide range of advanced performance-enhancing features. Port-based and tagged VLANs, plus support for automatic GVRP VLAN registration provide traffic security and efficient use of network bandwidth. QoS priority queueing ensures the minimum delay for moving real-time multi-media data across the network. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation.
Overview Traffic Priority The switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using two distinct categories with Weighted Fair Queuing. It uses IEEE 802.1Q and 802.1p tags to prioritize incomming traffic based on input from the end-station application driver. These functions can be used, for example, to provide independent priorities for real-time video, real-time voice, guaranteeddelivery data, or best-effort data.
AT-8324SX Installation Guide AT-B17 Expansion Module Using multimode fiber optic cable, the AT-B17 Expansion Module with its 100Base-FX port and an SC connector can be connected to a remote site up to 2 kilometers (1.24 miles) away in full-duplex mode or up to 412 meters (1,351 feet) in half-duplex mode. This port operates only at 100 Mbps. However, the transmission mode is adjustable to full- or halfduplex via manual setting.
Overview Features and Benefits Connectivity # 24 dual-speed ports for easy Fast Ethernet integration and for protection of your investment in legacy LAN equipment # Auto-negotiation enables each RJ-45 port to automatically select the optimum communication mode (half- or full-duplex and 10 or 100 Mbps) if this feature is supported by the attached device; otherwise, the port can be configured manually # Independent RJ-45 10Base-T/100Base-TX ports with built-in wiring crossovers for straight-through cable co
AT-8324SX Installation Guide — AT-B17 Expansion Module with an 100Base-FX fiber module port and an SC connector that can connect to a remote site up to 2 kilometers/1.
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.
Network Planning Sample Topologies The AT-8324SX switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical topologies are described below. Collapsed Backbone The AT-8324SX switch is an excellent choice for mixed Ethernet and Fast Ethernet installations where significant growth is expected in the near future.
AT-8324SX Installation Guide Central Wiring Closet With up to 100 ports in a stack (i.e., 100 distinct segments), the 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. In addition, the switch is also connecting servers at 200 Mbps.
Network Planning Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media 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 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.
AT-8324SX Installation Guide Making VLAN Connections VLANs can be based on port groups, or each data frame can be explicitly tagged to identify the VLAN group it belongs to. When using port-based VLANs, ports can either be assigned to one specific group or to all groups. Port-based VLANs are suitable for small networks. A single switch can be easily configured to support several VLAN groups for various organizational entities (such as Finance and Marketing).
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 autonegotiation for duplex mode (half- or full-duplex) and flow control. Refer to Table 3 for the cabling specifications for this module. Table 3 Cabling Specifications for the AT-B15/LX Expansion Module Cable Fiber Bandwidth Maximum Cable Length 62.
Network Planning Application Notes # Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. # When a switch is connected to a hub or any kind of shared media, remember to turn OFF back pressure to prevent the attached port from being frequently partitioned due to the jamming packets.
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. Warning Class 1 laser product.

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.
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. 4. If installing multiple switches, mount them in the rack, one below the other, in any order. 5. If also installing RPUs, mount them in the rack below the other devices.
Installing the Stack Desktop or Shelf Mounting To rack mount devices, perform the following procedure: 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. 3. If installing a single switch only, go to Connecting to a Power Source on page 44. 4.
AT-8324SX Installation Guide Stacking A stack can have as many as four switches. 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). Figure 14 Stacking the Switches 2.
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. Be sure to stack the new device before connecting it to a power source. All switches in a stack must be powered ON to allow traffic to pass across the stack’s backplane.
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. Twisted Pair Devices Each device requires an UTP cable with RJ-45 connectors at both ends. For 100Base-TX connections, Category 5 or better cable is required; for 10Base-T, Category 3 or better cable can be used.

Each 1000Base-SX device requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at both ends. Each 1000Base-LX device requires 10/125 micron single-mode 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. - If the switch is installed in a rack, check the connections to the punch-down block and patch panel.
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 to shutdown.
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. Then verify that you entered the correct IP address.
