  • Page 24: Optional Expansion Modules

    Overview Traffic Priority The switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using two distinct categories with Weighted Fair Queuing. It uses IEEE 802.1Q and 802.1p tags to prioritize incomming traffic based on input from the end-station application driver.

  • Page 29: Chapter 2 Network Planning

    Chapter 2 Network Planning An Ethernet or Fast Ethernet 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.
  • Page 30: Sample Topologies

    Some typical topologies are described below. Collapsed The AT-8324SX switch is an excellent choice for mixed Ethernet and Fast Backbone Ethernet installations where significant growth is expected in the near future.
  • Page 31: Central Wiring Closet

    With up to 100 ports in a stack (i.e., 100 distinct segments), the Closet AT-8324SX switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10Base-T/100Base-TX ports on the AT-8324SX stack are providing 100 Mbps connectivity for up to 100 segments through Ethernet hubs.
  • Page 32: Remote Connections With Fiber Cable

    Fiber optic technology allows for longer cabling than any other media Connections with type (up to 2 kilometers/1.24 miles for 100 Mbps fiber at full-duplex). The AT-8324SX switch can serve as a collapsed backbone, providing direct Fiber Cable connectivity for a widespread LAN. The 100 Mbps fiber module can be used to interconnect remote Fast Ethernet segments, while the Gigabit fiber module can be used to interconnect buildings in a campus setting.

    VLAN. When VLANs cross separate switches, it is therefore better to use VLAN tagging. This allows you to assign multiple VLAN groups to the trunk ports (that is, tagged ports) connecting different switches. AT-8324SX Fast Ethernet Switch 10BASE-T / 100BASE-TX SWITCH FAST ETHERNET...
  • Page 34: Connectivity Rules

    Network Planning Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for Ethernet and Fast Ethernet. 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.
  • Page 35: 10/100 Mbps Fast Ethernet

    AT-8324SX Installation Guide The AT-B15/LX has one 1000Base-LX fiber optic port with a SC connector. This module operates at 1 Gbps and supports auto- negotiation for duplex mode (half- or full-duplex) and flow control. Refer to Table 3 for the cabling specifications for this module.
  • Page 36: Application Notes

    # For network applications that actually require routing (such as when interconnecting dissimilar network types or distinct VLANs), you may have to attach the AT-8324SX switches directly to a router or Layer 3 switch.
