    TACK Overview SMC’s TigerStack III 10/100 SMC6826MPE is a 24-Port Fast Ethernet PoE Switch with 24 10BASE-T/100BASE-TX RJ-45 ports and two combination ports — 10/100/1000BASE-T ports that operate in combination with Small Form Factor Pluggable (SFP) transceiver slots An optional SFP stacking transceiver is available for connecting up to eight units to a 2 Gbps stack backplane.

  • Page 22: Switch Architecture

    SFP slots. The optional SFP stacking transceiver enables up to eight units to be connected together through a 1 Gbps stack backplane. The switch stack can be managed from a master unit using a single IP address.

    VERVIEW from the switch over the Ethernet cable without requiring its own separate power source. This capability gives network administrators centralized power control for devices such as IP phones and wireless access points, which translates into greater network availability. For each attached 802.3af-compliant device, the switch automatically senses the load and dynamically supplies the required power.

  • Page 24: Description Of Hardware

    TACK Description of Hardware 10/100BASE-T Ports The PoE switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All 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. (See “10/100BASE-TX Pin Assignments” on page B-2.)

  • Page 25: Port And System Status Led Indicators

    Port and System Status LED Indicators The switch base unit also includes a display panel for key system and port indications that simplify installation and network troubleshooting. The LED indicators, which are located on the front panel for easy viewing, are shown below and described in the following tables.

  • Page 33: 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.

    Fast Ethernet or Gigabit Ethernet ports. In the figure below, the switch is operating as a collapsed backbone for a small LAN. It is providing dedicated 10 Mbps full-duplex connections to workstations and 100 Mbps full-duplex connections to power users and servers.

  • Page 36: Network Aggregation Plan

    When up to eight switch units are stacked together, they form a single “virtual” switch containing up to 200 ports. The whole stack can be managed through the Master unit using a single IP address.

  • Page 37: Remote Connections With Fiber Cable

    550 m, a 1000BASE-LX single-mode fiber (SMF) link can run up to 5 km, and a 1000BASE-LH single-mode fiber (SMF) link can run up to 70 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

  • Page 38: Making Vlan Connections

    ETWORK LANNING Making VLAN Connections This switch supports 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.

  • Page 39: 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.

  • Page 49: Stacking Switches

    Stacking Switches The switch supports stacking up to eight units through an optional SFP stacking transceiver. Each stacking connection provides a 2 Gbps high-speed link using USB stacking cables. The stacking transceiver must be installed in the port 25 SFP slot. Each stacking transceiver has two connectors, Tx and Rx, for attaching stacking cables.

  • Page 50: Connecting Switches In A Stack

    To connect up to eight switches in a stack, perform the following steps: 1. Install SFP stacking transceivers into the port 25 slot for each switch in the stack. 2. Plug one end of a stack cable into the Tx (top) port of the top unit 3.
  • Page 51 6. 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 stack will not function.

  • Page 56: Power-Over-Ethernet Connections

    The switch delivers power to a device using the two signal wire pairs in UTP or STP cable (RJ-45 pins 1, 2, 3, and 6). The switch can provide up to 15.4 W of power continuously on each 10/100 Mbps port. However, taking into account some power loss over the cable run, the amount of power that can be delivered to a terminal device is 12.95 W.

  • Page 57: Cabling Guidelines

    Cabling Guidelines The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs). See Appendix B for further information on cabling.
