DESCRIPTION OF HARDWARE Management Options These switches contain a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status. They also include a management agent that allows you to configure or monitor the switch using its embedded management software, or via SNMP applications.
ABOUT THE TIGERSTACK 10G SFP Slots The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the RJ-45 ports (ports 21~24 for the SMC8724M and ports 45~48 for the SMC8748M). In its default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a valid link on its port, the associated RJ-45 port is disabled and cannot be used. The switch can also be configured to force the use of an RJ-45 port or SFP slot, as required.
DESCRIPTION OF HARDWARE Status LEDs The switch base unit also includes a display panel for key system and port indications that simplify installation and network troubleshooting. The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following table.

ABOUT THE TIGERSTACK 10G 1-10
CHAPTER 2 NETWORK PLANNING 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.
NETWORK PLANNING Application Examples The TigerStack 10G 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 10G is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
APPLICATION EXAMPLES Network Aggregation Plan With 24 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision domains), either of the switches can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100/1000BASE-T ports in a stack of 48-port switches are providing 1000 Mbps connectivity through stackable switches. In addition, the switches are also connecting several servers at 1000 Mbps.
NETWORK PLANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to 100 km. This allows a switch stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
APPLICATION EXAMPLES Making VLAN Connections These switches support VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.
NETWORK PLANNING 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. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. 3.
CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerStack 10G 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.
INSTALLING THE SWITCH Ethernet Cabling To ensure proper operation when installing the switches into a network, make sure that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation. Check the following criteria against the current installation of your network: ◆ Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better for 100BASE-TX, and Category 5e, 6 or better for 1000BASE-T.
EQUIPMENT CHECKLIST Equipment Checklist After unpacking the TigerStack 10G unit, 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 SWITCH Mounting A TigerStack 10G unit can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: 3-4 ◆ Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range. (See page C-2.

INSTALLING THE SWITCH Connecting Switches in a Stack To connect up to eight switches in a stack, perform the following steps: 1. Plug one end of the stack cable (ordered separately) in the Down (right) port of the top unit. 2. Plug the other end of the stack cable into the Up (left) port of the next unit. 3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at the Down port on the top unit and ending at the Up port on the bottom unit (stacking up to 8 units). 4.
CONNECTING SWITCHES IN A STACK 5. Select the Master unit in the stack by pressing the push button in on only one of the switches. Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the system will select the unit with lowest MAC address as the Master. Stacking Topologies All units in the stack must be connected via stacking cable.
INSTALLING THE SWITCH Connecting to a Power Source To connect a device to a power source: 1. Insert the power cable plug directly into the receptacle located at the back of the device. 100 -240V~ 50-60Hz 2A Figure 3-7 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.
CONNECTING TO THE CONSOLE PORT Connecting to the Console Port The DB-9 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The on-board configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following tables.
INSTALLING THE SWITCH 3-12
CHAPTER 4 MAKING NETWORK CONNECTIONS Connecting Network Devices The TigerStack 10G units are designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to devices using optional SFP transceivers. Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
MAKING NETWORK CONNECTIONS Connecting to PCs, Servers, Hubs and Switches 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 4-1 Making Twisted-Pair Connections 2. If the device is a PC card and the 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 the next page.) Otherwise, attach the other end to an available port on the switch. 3.
TWISTED-PAIR DEVICES Network Wiring 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.
MAKING NETWORK CONNECTIONS Fiber Optic SFP Devices An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or 1000BASE-ZX) can 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 LC connector at both ends. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends.
FIBER OPTIC SFP DEVICES 3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation. 46 47 48 Mast Sele er ct Stack ID Stack Stack M aste Link r Pow er RPU 45 Mod ule Diag 46 47 Con sole 48 Figure 4-3 Making LC Port Connections 4. As a connection is made, check the green Link LED on the switch corresponding to the port to be sure that the connection is valid.
MAKING NETWORK CONNECTIONS Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. 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.
CONNECTIVITY RULES Table 4-3 Maximum 1000BASE-LX Fiber Optic Cable Length Fiber Diameter Fiber Bandwidth Cable Length Range Connector 9/125 micron single-mode fiber N/A 2 m - 5 km (7 ft - 3.2 miles) LC Table 4-4 Maximum 1000BASE-ZX Fiber Optic Cable Length Fiber Diameter Fiber Bandwidth Cable Length Range Connector 9/125 micron single-mode fiber N/A 70* - 100 km (43.5 - 62.
MAKING NETWORK CONNECTIONS Cable Labeling and Connection Records When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption. To best manage the physical implementations of your network, follow these guidelines: 4-8 ◆ Clearly label the opposing ends of each cable.
APPENDIX A TROUBLESHOOTING Diagnosing Switch Indicators Table A-1 Troubleshooting Chart Symptom Action Power LED is Off • Check connections between the switch, the power cord, and the wall outlet. • Contact your dealer for assistance. • Contact SMC Technical Support. Power LED is Amber • Internal power supply has failed. Contact your local dealer for assistance. Diag LED is Amber • Power cycle the switch to try and clear the condition.
TROUBLESHOOTING Table A-1 Troubleshooting Chart Symptom Action Stack Link LED is Flashing Green/Amber • The uplink/downlink has failed. • Check that the stacking cables are connected properly. Replace the cable if necessary. • Power cycle the switch to try and clear the condition. • Verify that the switch and attached device are powered on. • Be sure the cable is plugged into both the switch and corresponding device.
IN-BAND ACCESS 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 tools. 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.
TROUBLESHOOTING cable is disconnected, the entire stack reboots and resumes normal operation and management using line-topology stacking through the remaining stack connections. Also, any changes to the stack including powering down of a unit or the insertion of a unit causes the stack to reboot.
APPENDIX B CABLES Twisted-Pair Cable and Pin Assignments For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
CABLES 10BASE-T/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps or 1000 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

CABLES 1000BASE-T Pin Assignments All 1000BASE-T ports 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. 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.
TWISTED-PAIR CABLE AND PIN ASSIGNMENTS 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. Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT).
CABLES Fiber Standards The current TIA (Telecommunications Industry Association) 568-A specification on optical fiber cabling consists of one recognized cable type for horizontal subsytems and two cable types for backbone subsystems. Horizontal 62.5/125 micron multimode (two fibers per outlet). Backbone 62.5/125 micron multimode or single mode. TIA 568-B will allow the use of 50/125 micron multimode optical fiber in both the horizontal and backbone in addition to the types listed above.
