  • Page 10: Hardware Description

    8-Port 1000BASE-TX Web-Smart Ethernet Switch with 2 SFP Dual Media Ports 2.3 Hardware Description 2.3.1 F RONT ANEL There are 8 TP Gigabit Ethernet ports and 2 SFP fiber ports for optional removable modules on the front panel of the switch. LED display area contains a Power LED, which indicates the power status and 8 ports working status of the switch.

  • Page 11: Rear Panel

    2.4 Optional SFP Fiber Transceiver Modules Ports 7–8 on the LGB2008A-R2 include two types of media: twisted-pair (TP) and optional small form factor pluggable (SFP) fiber (LC, BiDi LC, etc.) modules. The twisted-pair ports are the switch’s two rightmost RJ-45 twisted-pair connectors (ports 7–8).

  • Page 12: Installation

    2. Slide the module into the slot as shown in Figure 3-1. Make sure that the module is properly seated against the slot socket/connector. 8-Port 1000BASE-TX Web Smart Ethernet Switch (LGB2008A-R2) SFP Fiber Transceiver Module Figure 3-1. Installing an optional SFP fiber transceiver in the switch.

  • Page 13: Connecting The Cable

    3.1.2 C ONNECTING ABLE The switch’s twisted-pair ports support MDI/MDI-X auto-crossover, so you can use either straight-through or cross-pinned UTP cable. Use Category 5 or 5e grade RJ-45 twisted-pair cable to connect up to 24 network devices (such as workstations or servers) to the switch’s UTP ports.

  • Page 14: Switch Cascading

    3.2.3 S WITCH ASCADING Theoretically, the switch partitions the collision domain for each port in switch cascading so that you may up-link an unlimited number of switches. In practice, the network extension (cascading levels and overall diameter) must comply with the IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, which limit the timing requirement from physical signals defined by the Media Access Control (MAC) and PHY802.3 series specification, and timer from some OSI layer 2 protocols such as 802.1d, 802.1q, and LACP.
  • Page 15 Example 2: Port-based VLAN If VLAN is enabled and configured, each node in the network that can communicate with each other directly is in the same VLAN. The switch supports both port-based VLAN and tag-based VLAN. They are different in practical deployment, especially in physical location.
