CHAPTER 1 ABOUT THE TIGERSTACK II 10/100/1000 Overview SMC’s TigerStack II 10/100/1000 SMC8824M and SMC8848M are intelligent multilayer switches (Layer 2, 3) with 24/48 10/100/ 1000BASE-T ports, four of which are combination ports* that are shared with four SFP transceiver slots (see Figure 1-1, Ports 21-24/45-48). The rear panel provides two slots for single-port 10 Gigabit Ethernet hot-swappable expansion modules, and two stacking ports.
ABOUT THE TIGERSTACK II 10/100/1000 These switches can be used to augment or completely replace slow legacy routers, off-loading local IP traffic to release valuable resources for non-IP routing or WAN access. With wire-speed performance, these switches can significantly improve the throughput between IP segments or VLANs.
DESCRIPTION OF HARDWARE These switches include built-in stacking ports that enable up to eight units to be connected together through a 48 Gbps stack backplane. The switch stack can be managed from a master unit using a single IP address. These switches also include two slots on the rear panel for slide-in single-port 10GBASE modules with XFP transceivers. Network Management Options These switches contain a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status.
ABOUT THE TIGERSTACK II 10/100/1000 SFP Slots The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the RJ-45 ports (ports 21-24 for the SMC8824M and ports 45-48 for the SMC8848M). 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 Port and System Status LEDs These switches include 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 tables.

ABOUT THE TIGERSTACK II 10/100/1000 Optional Redundant Power Supply SMC supports an optional Redundant Power Supply (RPS), that can supply power to the switch in the event the internal power supply fails. Power Supply Sockets There are two power sockets on the rear panel of each switch. The standard power socket is for the AC power cord. The socket labeled “RPS” is for the optional Redundant Power Supply (RPS).
FEATURES AND BENEFITS Extender Module LEDs The optional 10GBASE slide-in module includes its own integrated LED indicators on the module’s front panel. The following table describes the LEDs. Table 1-3 Module LEDs LED Condition Link/ On/Flashing Activity Green Off Status Port has a valid link at 10 Gbps. Flashing indicates activity. There is no link on the port.

Performance • Transparent bridging. • Aggregate duplex bandwidth of up to 128 Gbps for the SMC8824M or 176 Gbps for the SMC8848M.
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. These switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.
NETWORK PLANNING Application Examples The TigerStack II 10/100/1000 is not only designed to segment your network, but also to provide a wide range of options in setting up network connections and linking VLANs or IP subnets. Some typical applications are described below. Collapsed Backbone The TigerStack II 10/100/1000 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), a Gigabit switch stack 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 Gigabit Ethernet switches are providing 1000 Mbps connectivity through stackable switches. In addition, the switches are also connecting several servers at 10 Gbps.
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. For network applications that require routing between dissimilar network types, you can attach these switches directly to a multiprotocol router. 3.
CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerStack II 10/100/1000 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 5, 5e or 6 for 1000BASE-T.
EQUIPMENT CHECKLIST Equipment Checklist After unpacking the TigerStack II 10/100/1000 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 II 10/100/1000 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.
MOUNTING To rack-mount devices: 1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit. Stack Ma ster Pwr Maste Selec r t Stack ID RPS Modu le Stack Diag Link Cons Tig 10 erSta /1 8848 00/1 ck II 00 M 0 ole 45 46 47 48 Figure 3-2 Attaching the Brackets 2. Mount the device in the rack, using four rack-mounting screws (not provided).
INSTALLING THE SWITCH 3. If installing a single switch only, turn to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, mount them in the rack, one below the other, in any order. 5. If also installing an RPS, mount it in the rack below the other devices. Desktop or Shelf Mounting 1. Attach the four adhesive feet to the bottom of the first switch.
INSTALLING AN OPTIONAL MODULE INTO THE SWITCH Installing an Optional Module into the Switch M1 Figure 3-5 Installing an Optional Module Note: The slide-in modules are hot-swappable, you do not need to power off the switch before installing or removing a module. To install an optional module into the switch, do the following: 1. Remove the blank metal plate (or a previously installed module) from the appropriate slot by removing the two screws with a flat-head screwdriver. 2.
INSTALLING THE SWITCH 6. The Module LED on the switch’s front panel should turn green to confirm that the module is correctly installed and ready to use.
CONNECTING SWITCHES IN A STACK 3. Slide the transceiver into the slot until it clicks into place. Note: SFP and XFP transceivers are hot-swappable. The switch does not need to be powered off before installing or removing a transceiver. However, always first disconnect the network cable before removing a transceiver. Note: SFP and XFP transceivers are not provided in the switch package. Connecting Switches in a Stack Figure 3-7 shows how the stack cables are connected between switches in a stack.
INSTALLING THE SWITCH 4. (Optional) To form a wrap-around topology, plug one end of a stack cable into the Down port on the bottom unit and the other end into the Up port on the top unit. Figure 3-7 Making Stacking Connections 5. Select the Master unit in the stack by pressing the Master 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.
CONNECTING SWITCHES IN A STACK Stacking Topologies All units in the stack must be connected via stacking cable. You can connect units in a simple cascade configuration, connecting Down ports to Up ports, from the top unit to the bottom unit. Using this “line” topology, if any link or unit in the stack fails, the stack is split and two separate segments are formed. The Stack Link LEDs on the units that are disconnected flash to indicate that the stack link between them is not functioning.
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 socket located at the back of the device. Figure 3-8 Power Socket 2. Plug the other end of the cable into a grounded, 3-pin, AC power source. 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 socket type in your country. 3.
CONNECTING TO THE CONSOLE PORT Connecting to the Console Port The RJ-45 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 table.
INSTALLING THE SWITCH 3-14
CHAPTER 4 MAKING NETWORK CONNECTIONS Connecting Network Devices The TigerStack II 10/100/1000 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 XFP or 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 “Network Wiring Connections” on page 4-3.) Otherwise, attach the other end to an available port on the switch.
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 single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.
10 GBPS FIBER OPTIC CONNECTIONS 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. 39 40 41 42 43 44 45 46 47 48 Stac k Ma ste r Pwr Maste Selec r t Stac k ID RPS Modu le Stac Diag k Lin k Cons ole Tig 10 erSta /1 8848 00/1 ck II 00 M 0 45 46 47 48 Figure 4-3 Making Connections to SFP Transceivers 4.
MAKING NETWORK CONNECTIONS Warning: These switches use 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. Note: When selecting a fiber device, considering safety, please make sure that it can function at a temperature that is not less than the recommended maximum operational temperature of the product.
10 GBPS FIBER OPTIC CONNECTIONS M1 Figure 4-4 Connecting to an XFP Transceiver 4. As a connection is made, check the Link LED on the module to be sure that the connection is valid. The 10G fiber optic ports operate at 10 Gbps full duplex. The maximum length for fiber optic cable operating at 10 Gbps will depend on the fiber type as listed under “10 Gbps Ethernet Collision Domain” on page 4-8.
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.

CABLE LABELING AND CONNECTION RECORDS 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: • 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 (Continued) Symptom Action Stack Link LED is Flashing Green/Amber • The uplink/downlink has failed. • For the indicated stack link, check that the stacking cables are properly connected. Replace the stacking 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.
POWER AND COOLING PROBLEMS 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.
TROUBLESHOOTING Stack Troubleshooting If a stack fails to initialize or function, first check the following items: • Check that all stacking cables are properly connected. • Check if any stacking cables appear damaged. • Check that only one Stack Master button is pressed in. • Check that all switches in the stack are powered on. After checking all items, reboot all the switches in the stack. Switches in the stack may be configured using a ring- or line-topology.
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 connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
TWISTED-PAIR CABLE AND PIN ASSIGNMENTS Straight-Through Wiring If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on these switches, you can use either straight-through or crossover cable to connect to any device type.) You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet connections.
CABLES Crossover Wiring If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (indicating MDI-X) or neither port is labeled with an “X” (which indicates MDI), a crossover must be implemented in the wiring. (When auto-negotiation is enabled for any RJ-45 port on these switches, you can use either straight-through or crossover cable to connect to any device type.
TWISTED-PAIR CABLE AND PIN ASSIGNMENTS 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.
CABLES Note that when testing your cable installation, be sure to include all patch cables between switches and end devices. Adjusting Existing Category 5 Cabling to Run 1000BASE-T 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 and correct the problem: 1. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables. 2.
