IGERSTACK

Overview

SMC’s TigerStack™ 100 is a stackable switch with 24 100BASE-FX MT-RJ ports, plus two slots for optional slide-in 100BASE-FX or 1000BASE-X modules. One of these slots can also be used for an optional stacking module that allows you attach up to four switches to a 9.6 Gbps high-speed backplane. There is also an SNMP-based Network Management Module installed in the rear panel. This module supports both in-band and out-of-band access for managing the switch and the attached stack.

Note:

A switch stack, or a switch in a standalone configuration, must have Network Management Module installed to enable all ports. The base unit alone has all ports disabled by default.

Switch Architecture

The TigerStack 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 TigerStack 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 9.6 Gbps stack backplane provides enough bandwidth for the most demanding environment. Moreover, you can use a 100 Mbps single-mode fiber module for connecting to a remote site, or a Gigabit module for a high-speed backbone connection.

Management Options

This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status. It also includes a Network Management Module that allows the entire stack to be managed in-band via SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or remotely via Telnet. The switch also provides a serial port on the rear panel for out-of-band management.

Note: Only one Network Management Module must be installed in the

stack for the current firmware release.

Description of Hardware

100BASE-FX MT-RJ Ports

These ports are MT-RJ multimode fiber ports that can be connected to workstations and servers with 62.5/125 micron or 50/125 micron multimode fiber cable.

Each of these ports support half- and full-duplex operation at 100 Mbps. Note that 100BASE-FX ports do not support auto-negotiation of duplex mode, so this has to be configured manually. However, the ports do support IEEE 802.3x auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.

Network Management Module

SMC6924VFNMM

Figure 1-5. Network Management Module

This switch includes a Network Management Module on the rear panel. This module can manage the switch and 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 null modem cable. This allows you to access the out-of-band interface. (See Apendix B for a description of wiring options.)

The Network Management Module provides a wide range of advanced performance-enhancing features. Multicast filtering provides support for real-time network applications. Port-based and tagged VLANs provide traffic security and efficient use of network bandwidth. QoS priority queueing ensures the minimum delay for across the network. Flow control bottlenecks caused by port saturation. And broadcast storm control prevents broadcast traffic storms from engulfing the network.

Some of this switch’s advanced features are described below. For a detailed description, refer to the Management Guide.

Spanning Tree Protocol

The TigerStack 100 supports IEEE 802.1D Spanning Tree Protocol. 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, this 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.

VLANs

The TigerStack 100 supports up to 256 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 severely degrade performance in a flat network.

100

• Simplify network management for node changes/moves by remotely configuring VLAN membership for any port, rather than having to manually change the node’s connection.

• Provides 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.

Multicast Switching

Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN.

1-6

BOUT THE TIGERSTACK

The switch uses IGMP Snooping and IGMP to manage multicast group registration.

Traffic Priority

This 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 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. These functions can be used to provide independent priorities for delay-sensitive data and best-effort data.

Introduction to Switching

A network 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.

Sample Applications

The TigerStack 100 is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below.

Collapsed Backbone

The TigerStack 100 is an excellent choice for mixed 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 TigerStack to a Fast Ethernet hub or switch, add another TigerStack to the stack, or link to another workgroup using a Gigabit connection.

In the figure below, the TigerStack 100 is operating as a collapsed backbone for a small LAN. It is providing dedicated 200 Mbps full-duplex connections to workstations and servers.

With up to 104 ports in a stack (i.e., 104 distinct segments), the TigerStack 100 can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.

In the figure below, the MT-RJ ports on the TigerStack stack are providing 100 Mbps connectivity for up to 96 end nodes. In addition, the switch is also connecting servers at 2 Gbps.

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A 100 Mbps multimode fiber (MMF) link can run up to 2 km (at full duplex), and a 100 Mbps single-mode fiber (SMF) link can run as far as 10 km. A 1000BASE-LX SMF Gigabit link can also connect to a site up to 5 km away. This allows the TigerStack 100 to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. The 100BASE-FX SMF module can be used to interconnect remote Fast Ethernet segments. While a Gigabit module can be used for a high-speed connection between floors in the same building, or to connect to other buildings in a campus setting. The figure below illustrates a TigerStack 100 stack connecting multiple segments with fiber cable.

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 any number of 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 Spanning Tree Protocol, 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

1. 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.

2. 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.

3. For network applications that require routing (such as when interconnecting dissimilar network types or distinct VLANs), you may have to attach the TigerStack 100 units directly to a router or Layer 3 switch (such as the SMC6724L3).

Selecting a Site

TigerStack 100 units 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.

◆ The site should:

• be at the center of all the devices you want to link and near a power outlet.

• be able to maintain its temperature within 0° to 50° C and its humidity within 5% to 95%, non-condensing

• provide adequate space (approximately two inches) on all sides for proper air flow

• be accessible for installing, cabling and maintaining the devices

• allow the status LEDs to be clearly visible

◆ Make sure twisted-pair cable is always routed away from power lines,

fluorescent lighting fixtures and other sources of electrical interference, such as radios, transmitters, etc.

◆ Make sure that a separate grounded power outlet that provides 100 to

240 VAC, 50 to 60 Hz, is within 8 feet of each device and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended.

MT-RJ Fiber Connections

Each device requires a 62.5/125 micron or 50/125 micron multimode fiber optic cable with MT-RJ connectors at both ends.

1. Remove and keep the MT-RJ port’s plastic cover. When not connected to a fiber cable, the cover should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs using an appropriate MT-RJ cleaning kit. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

3. Connect one end of the cable to the MT-RJ port on the switch and the other end to the MT-RJ port on the other device. Since MT-RJ connectors are keyed, the cable can be attached in only one orientation.

4. As each connection is made, check the Link LED on the switch’s front panel for the corresponding port to be sure that the connection is valid.

You can run a fiber link up to 2 km (1.24 mi.) in full-duplex mode, and 412 m (1351 ft.) in half-duplex mode. However, note that power budget and timing constraints must also be considered when calculating the maximum cable length for your specific environment.

SC Fiber Connections

An optional slide-in 100BASE-FX module may be used for backbone and long distance connections. A 1000BASE-X module may also be used for a backbone connection between switches, or for connecting to a high-speed server.

Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at both ends. If you need to connect to a device with 62.5/125 micron cable that has ST-type connectors, SMC provides an optional SC-ST Converter (Part Number: 99-012034-091).

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an SC connector at both ends.

Warning: This switch uses lasers to transmit signals over fiber optic

cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

1. Remove and keep the SC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

The 100BASE-FX fiber optic ports operate only at 100 Mbps, full duplex. You can run a single-mode fiber link up to 6.21 miles (10 kilometers). However, note that power budget constraints must also be considered when calculating the maximum cable length for your specific environment.

The 1000BASE-SX fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of 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 Collision Domain” on page 2-6.

AKING NETWORK CONNECTIONS

1000BASE-T Twisted-Pair Connections

A 1000BASE-T connection requires a shielded or unshielded twisted-pair (STP or UTP) cable with RJ-45 connectors at both ends. For all connections, Category 5, 5e, or better (recommended) cable is required with all four wire pairs connected. You should also test the cable installation for IEEE 802.3ab compliance. See “1000BASE-T Cable Requirements” on page B-3.

Cabling Guidelines

The RJ-45 port on the SMC6900GT module supports 1000, 100, and 10 Mbps Ethernet operation, with auto-negotiation of speed, duplex mode, and flow control. Because 1000BASE-T ports support automatic MDI/ MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.

Caution: 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.

Connecting to PCs, Servers, Hubs and Switches

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

4-5

AKING NETWORK CONNECTIONS

Figure 4-2. Making Twisted-Pair Connections

2. If the device is a network card and the TigerStack 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 the next page). Otherwise, attach the other end to the port on the 1000BASE-T module.

Make sure the twisted pair cable does not exceed 100 meters (328 ft.) in length.

Note: When connected to a shared collision domain (such as a hub

with multiple workstations), switch ports must be set to half-duplex mode and back pressure flow control disabled.

3. As the connection is made, the green Activity LED (on the TigerStack) corresponding to the module port will start to flash, indicating that the connection is valid and traffic is passing through the port.

Wiring Closet 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 the port on the 1000BASE-T module, 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.

ROUBLESHOOTING

Diagnosing Switch Indicators

Troubleshooting Chart

Symptom Action

Power LED is Off • Internal or redundant power supply has failed or is

disconnected.

• Check connections 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.

• Contact SMC Technical Support.

Power LED is Flashing • The switch is either downloading firmware or running

the Power-On Self-Diagnostics Test (POST). If this LED does not stop flashing, then POST has failed, and you should contact SMC Technical Support.

Link LED is Off • Verify that the switch and attached device are powered

on.

• Be sure the cable is plugged into both the switch and corresponding device.

• Verify that the proper cable type is used and its length does not exceed specified limits.

• Check the adapter on the attached device and cable connections for possible defects. Replace the defective adapter or cable if necessary.

A-1

ROUBLESHOOTING

Power and Cooling Problems

If the power indicator 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. 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 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 SMC Technical Support for assistance.

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.

In-Band Access

You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software such as EliteView. 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: You can configure the management agent to accept from one to

four simultaneous Telnet sessions. If the maximum number of sessions already exists, an additional Telnet connection will not be able to log into the system.

RJ-45 Port and Cable 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.

The RJ-45 port on the SMC6900GT module supports 1000, 100, and 10 Mbps Ethernet operation, with auto-negotiation of speed, duplex mode, and flow control.

1000BASE-T Pin Assignments

1000BASE-T ports switch support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1-8, at one end of the cable, are connected straight through to pins 1-8 at the other end of the cable.

Use 100-ohm Category 5, 5e, or better unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for 1000BASE-T connections. Also be

that the length of any twisted-pair connection does not exceed 100

sure meters (328 feet)

B-2

The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.

1000BASE-T Cable Requirements

ABLES

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or better cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3ab standards.

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard.

B-3

ABLES

Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include all patch cables between switches and end devices.

Adjusting Existing Category 5 Cabling

If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try to correct the problem:

1. Replace any Category 5 patch cables with high-performance Category 5e or better cables.

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.

Console Port Pin Assignments

The DB-9 serial port on the switch’s rear panel is used to connect to the switch for out-of-band console configuration. The on-board menu-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program.
