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. This module supports both in-band and out-of-band access for managing the switch and the attached stack.

Options
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. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.
This AT-8324SX switch can be used in a standalone configuration, or can be stacked up to four high to form a single logical switch with up to 104 ports. When stacked, the 4 Gbps stack backplane provides enough bandwidth for the most demanding environment. Moreover, you can use a 100 Mbps fiber module for connecting to a remote site, or a Gigabit module for a high-speed backbone connection.
This switch contains a comprehensive array of LEDs for "at-a-glance" monitoring of network and port status. The optional AT-BMGMT Management Module allows the entire stack to be managed in-band via SNMP, RMON (Groups 1, 2, 3 and 9), or with a Web browser, as well as remotely via Telnet or SLIP. This module also has a serial port for out-of­band management.
There’s also support for the AT-BRPS8000 Redundant Power Supply to ensure continuous operation in the event of an AC power loss or the failure of the switch’s internal power supply.

Description of Hardware

AT-8324SX Installation Guide
10Base-T/

100Base-TX Ports

Status LEDs

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).
Each of these ports support auto-negotiation, so the optimum transmission mode (half- or full-duplex) and data rate (10 or 100 Mbps) are selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually.
The LEDs, which are located on the front panel for easy viewing, are described in the following table.

(Continued)
The top expansion slot on the rear panel of the switch is for the optional AT-BMGMT Management Module (Figure 3). This module can manage the switch or the attached stack. It offers a variety of management options, including SNMP, RMON and a Web-based interface. This module also includes an RS-232 port for out-of-band management. This is an RS-232 serial port with a DB-9 connector. A PC may be connected to this port for configuration and monitoring purposes out-of band via a full-handshaking null modem cable. You can also make a remote connection to this port via modems. This allows you to access the out-of-band interface, or to establish a network connection using SLIP protocol. (See Appendix A for a description of wiring options.)

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. And broadcast storm control prevents broadcast traffic storms from engulfing the network. Some of the management features are described below. For a detailed description, refer to the
Management Software User’s Guide
, which is available from the Allied
AT-S29
Telesyn web site.
Spanning Tree Protocol
The AT-8324SX Fast Ethernet Switch supports ANSI/IEEE 802.1d Spanning Tree Protocol (STP). This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, the protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network. This prevents the creation of network loops. However, if the chosen path should fail for any reason, an alternate path will be activated to maintain the connection.
The default setting for the STP is "enabled." This protocol may be configured (enabled or disabled) out-of-band via the serial console port or in-band via the Web interface, Telnet, or SNMP network management software.
VLANs
The AT-8324SX switch supports up to 16 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. By segmenting your network into VLANs, you can:
Eliminate broadcast storms which severly degrade performance
#
in a flat network.
Simplify network management for node changes/moves by
#
remotely configuring VLAN membership for the concerned port, rather than having to manually change the node’s IP address.
Provide data security by restricting all traffic to the originating
#
VLAN, except where a connection has been configured between separate VLANs using a router or Layer 3 switch.
23
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.

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.
When performance bottlenecks are caused by congestion at the network access point (such as the network card for a high-volume file server), the device experiencing congestion (server, power user or hub) can be attached directly to a switched port. And, by using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.
When networks are based on repeater (hub) technology, the maximum distance between end stations is limited. For Ethernet, there may be up to four hubs between any pair of stations; for Fast Ethernet, the maximum is two. This is known as the hop count. However, a switch turns the hop count back to zero, so subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.
A switch can be easily configured in any Ethernet or Fast Ethernet network to significantly boost bandwidth while using conventional cabling and network cards.
Note
When connected to a shared collision domain (such as a hub with multiple workstations), each switched port may operate only in half-duplex mode, and back pressure flow control should be disabled.

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. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers. When the time comes for further expansion, just cascade the AT-8324SX switch to an Ethernet or Fast Ethernet hub or switch, add another AT-8324SX switch to the stack, or link to another workgroup using a Gigabit connection.
In the figure below, the AT-8324SX switch is operating as a collapsed backbone for a small LAN. It can provide dedicated 10 Mbps or 100 Mbps half-duplex connections to workstations and 200 Mbps full-duplex connections to power users and servers.

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.

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.

Making VLAN
Connections
VLAN 1 R & D
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).
When you expand port-based VLANs across several switches, you need to make a separate connection for each VLAN group. This approach is, however, inconsistent with the STP, which can easily segregate ports that belong to the same 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.

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.
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.

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.
To connect each device to a power source, perform the following procedure:
1. Insert the power cable plug directly into the receptacle located at the back of the device.
Figure 15
Power Receptacle
2. Plug the other end of the cable into a grounded, 3-pin socket.
Note
For international use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country.
3. Check the front-panel LEDs as the device is powered ON to be sure the Power LED is lit. If not, check that the power cable is correctly plugged in. The MGMT LED on the uppermost switch will be lit.
4. If you have purchased redundant power units, connect them to the other devices and to an AC power source now, following the instructions included with the package.

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

Cabling
Guidelines
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.
Every twisted pair connection must have a wiring crossover to transmit and receive data. For convenience, this crossover is built into all RJ-45 ports on the switch (these are fixed crossover ports). Since network cards do not have a built-in wiring crossover, PCs can be connected to these ports with straight-through cable.
10Base-T/100Base-TX hubs and switches, on the other hand, may have either crossover or straight-through ports. For this reason, the type of cable used to connect these devices to the switch is determined by the port on the other device, as shown in the table below. (See Appendix A for further information on cabling.)

Warning
Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted pair cables with RJ-45 connectors that conform to FCC standards.
To connect devices to the switch, perform the following procedure:
1. Attach one end of a twisted pair cable segment to the device’s RJ-45 connector.
46
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
Connections
on page 47). Otherwise, attach the other end to an
Wiring Closet
available port on the switch.
If the device is a hub or switch, use the cable type indicated under
Cabling Guidelines
on page 45 and attach the other end to a port
on the AT-8324SX switch.
AT-8324SX Installation Guide
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.

Connections
Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows.
1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.
2. If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down block is located, and the other end to a modular wall outlet.
3. Label the cables to simplify future troubleshooting.

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. Each 1000Base-LX device requires 10/125 micron single-mode 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 slide-in module and the other end to the SC connector on the other device. Since SC connectors are keyed, the cable can be attached in only one manner. If you use an SC/ST converter with ST fiber ports, be sure to connect the Tx (Rx) connector on the slide-in module to the Rx (Tx) connector on the other device.
The Gigabit ports operate at 1 Gbps, half- or full-duplex, with auto­negotiation for duplex mode and flow control. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed under
1000 Mbps Gigabit Ethernet
on page 34.
48

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. Since SC connectors are keyed, the cable can be attached in only one manner. If you use an SC/ST converter with ST fiber ports, be sure to connect the Tx (Rx) connector on the slide-in module to the Rx (Tx) connector on the other device.
The fiber optic ports operate only at 100 Mbps, but can be manually configured to either half- or full-duplex. When using full-duplex, you can run a fiber optic link up to 2 kilometers (1.24 miles). However, when using half-duplex, you can only run a link up to 412 meters (0.25 miles). Note that timing constraints must also be considered when calculating the maximum cable length for your specific environment.

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. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact Allied Telesyn Technical Support for assistance.
52

Installation

AT-8324SX Installation Guide
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.
53
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. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.
Note
Up to four simultaneous Telnet connection are supported. If four sessions already exist, an additional Telnet connection will not be able to log into the system.
