The switch also includes one 10/100BASE-TX port for dedicated management access (which can be operated outside the data channel), and two slots for optional Gigabit Ethernet combination modules (one 10/100/1000BASE-T port shared with an SFP slot).

  • Page 22: About The Tigeraccess Switch

    This switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. For communications within the same VLAN, the switch uses store-and-forward switching to ensure maximum data integrity.

  • Page 23: Description Of Hardware

    The management port (RJ-45) provides a dedicated management channel that operates outside of the data transport network. This makes it possible to re-configure or troubleshoot the switch over either a local or remote connection to the management port when access via the data channel is not possible or deemed insecure.

  • Page 24: Console Port

    However, note that the interface connection parameters of this port cannot be configured. Console Port The console port on the switch’s front panel is an RJ-45 connection using a male DB-9 connector that enables a connection to a terminal for performing switch monitoring and configuration functions. The terminal may be a PC or workstation running terminal emulation software, or a terminal configured as a Data Terminal Equipment (DTE) connection.

  • Page 25: Alarm Interface Port

    Alarm Interface Port The DB-15 alarm port on the switch’s front panel can be used to provide alarm, service port, and BITS clock reference interfaces. The switch supports two sets of alarm relay contacts (major and minor), and 4 external customer site alarm inputs.

  • 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.

  • Page 35: Network Aggregation Plan

    Network Aggregation Plan With 28 parallel bridging ports (i.e., distinct collision domains), this switch 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 1 Gbps connectivity through cascaded switches.

  • Page 36: 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 10 km, and a 1000BASE-ZX link up to 70 km. This allows a switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

  • Page 37: 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 38: 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. To interconnect distinct VLANs or IP subnets, you can attach the switch to a standard Layer 3 router.

    6. To confirm that the module is correctly installed and ready to use, connect an active device to the module, and verify that the corresponding port indicator on the switch’s front panel turns green to show that there is a valid link.

  • Page 47: Grounding The Chassis

    Before powering on the switch, ground the switch to earth as described below. 1. Ensure that the rack on which the switch is to be mounted is properly grounded and in compliance with ETSI ETS 300 253. 2. Ensure that there is a good electrical connection to the grounding point on the rack (no paint or isolating surface treatment).

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

  • Page 61: Figure 4-3 Making Connections To Sfp Transceivers

    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.

    Twisted-Pair Cable and Pin Assignments For 10/100BASE-TX connections, the 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.

    100 meters (328 feet). The RJ-45 ports on the 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, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable.

  • Page 71: 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.
