  • Page 21: About The Tigerstack 1000

    Overview SMC’s TigerStack 1000 SMC8724ML3 and SMC8748ML3 are intelligent multilayer switches (Layer 2, 3) with 24/48 10/100/1000BASE-T ports, four of which are combination ports transceiver slots (see Figure 1-1, Ports 21-24/45-48). The rear panel provides a slot for single-port 10 Gigabit Ethernet hot-swappable expansion modules, and two stacking ports.

    SNMP applications. To manage the switch, you can make a direct connection to the RS-232 console port (out-of-band), or you can manage the switch through a network connection (in-band) using Telnet, the on-board web agent, or SNMP-based network management software.

  • Page 24: Sfp Slots

    SFP Slots The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the RJ-45 ports (ports 21-24 for the SMC8724ML3 and ports 45-48 for the SMC8748ML3). 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.

  • Page 31: Network Planning

    When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum 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.

  • Page 32: Application Examples

    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 connect to another hub or switch using one of the Gigabit Ethernet ports built into the front panel, a Gigabit Ethernet port on a plug-in SFP transceiver, or a 10G transceiver on the optional module.

  • Page 33: Network Aggregation Plan

    Network Aggregation Plan With 24 or 48 parallel bridging ports (i.e., 24/48 distinct collision domains), these 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 are providing 1000 Mbps connectivity through stackable switches.

  • Page 34: Remote Connections With Fiber Cable

    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.

  • Page 35: Making Vlan Connections

    VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks and all the VLANs assigned to the inter-switch links.

  • Page 36: Using Layer 3 Routing

    IP routers, except for a router to handle non-IP protocols and a gateway router linked to the WAN. Just assign an IP address to any VLANs that need to communicate. The switch will continue to segregate Layer 2 traffic based on VLANs, but will now provide inter-VLAN connections for IP applications.

  • Page 37: 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 multi- protocol router.

  • Page 48: Connecting Switches In A Stack

    Figure 3-7 shows how the stack cables are connected between switches in a stack. Each stacking connection is a 40 Gbps full-duplex high-speed serial link using proprietary stacking cables. The switch supports a line- and ring-topology stacking configuration, or can be used stand alone.

  • Page 50: Stacking Topologies

    NSTALLING THE WITCH Stacking Topologies All units in the stack must be connected via stacking cable. You can connect units in a simple cascade configuration, connecting Up ports to Down 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.

  • Page 51: Connecting To A Power Source

    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. 2. Plug the other end of the cable into a grounded, 3-pin, AC power source.

  • Page 56: Fiber Optic Sfp Devices

    AKING ETWORK 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.

  • Page 57: 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.

  • Page 58: Figure 4-4 Connecting To Xenpak Transceiver

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

    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.

    Power cycle the switch to try and clear the condition. • Verify that the switch and attached device are powered • 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.

  • Page 65: Power And Cooling Problems

    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.

  • Page 66: Stack Troubleshooting

    After checking all items, reboot all the switches in the stack. The switches allow you to configure ring- or line-topology stacking. When using ring-topology stacking configuration and a switch fails, or a stacking cable is disconnected, the entire stack reboots and resumes normal operation using line-topology stacking through the remaining stack connections.

  • Page 67: 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.

  • Page 68: 10Base-T/100Base-Tx Pin Assignments

    Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). The RJ-45 ports on the switch base unit 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...

  • Page 69: Straight-Through Wiring

    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.

  • Page 70: Crossover Wiring

    ABLES 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.

  • Page 71: 1000Base-T 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.
