Chapter 1: About the VDSL Switch-VS2512A Overview Accton’s Ethernet-over-VDSL system consists of end-user CPEs (Customer Premise Equipment) connected to a VDSL switch and splitter by standard telephone cable. The VDSL connection delivers an Ethernet data link rated up to 15 Mbps symmetric (full duplex), while simultaneously supporting standard telephone services.
About the VDSL Switch-VS2512A VDSL Technology VDSL (Very High Bit-Rate Digital Subscriber Line) is at the high-end of all the DSL technologies, offering the best combination of fiber optics and copper to provide high-speed broadband Internet access. VDSL’s primary application is in providing a broadband data service to multi-tenant residential or commercial buildings.
Overview Switch Architecture The VDSL Switch-VS2512A employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. Management Options This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status.
About the VDSL Switch-VS2512A Traffic Priority This switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using four distinct categories with Weighted Round Robin Queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. These functions can be used to provide independent priorities for delay-sensitive data and best-effort data.
Description of Hardware The switch also includes key system and port indicators that simplify installation and network troubleshooting. The front panel has LEDs for Ethernet link status/activity and VDSL link status, as well as system status indicators. The following figure shows the components of the VDSL Switch.

Chapter 2: Network Planning Introduction to Switching A network 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.
Network Planning Internet Connections The figure below shows a VDSL Switch-VS2512A and VDSL Splitter-VM2524 providing a broadband data service to a multi-tenant residential or commercial building. In this implementation, fiber optic cable carries data from a telephone company’s central office to the building; then the installed telephone copper wires take the data and deliver it to individual units within that building.
Sample Applications Making VLAN Connections VLANs can be based on port groups, or each data frame can be explicitly tagged to identify the VLAN group to which it belongs. When using port-based VLANs, ports can be assigned to one or more groups. Port-based VLANs are suitable for small networks. A single switch can be easily configured to support several VLAN groups for various organizational entities (such as Finance and Marketing).
Network Planning Application Notes 1. For network applications that require routing between dissimilar network types, you can attach the VDSL switch directly to a router. 2. The multimode fiber modules are fitted with SC connectors, but you can attach an ST plug to the switch using Accton’s optional SC-to-ST plug converter (Part Number: ST5002, for 62.5/125 micron cable only).
Chapter 3: Installing the VDSL Switch and Splitter Preparing the Site In multi-tenant buildings, phone lines coming from the service provider are generally attached to a PBX or MDF distribution box in the basement. These lines run from the PBX to a punch-down block, and then up to the POTS terminals for individual users. The following figure displays the normal wiring before installing the VDSL switch and splitter.

Installing an Optional Module Caution: DO NOT install slide-in modules with the switch powered on.
Installing the VDSL Switch and Splitter Installing a GBIC Transceiver Figure 3-6. Installing a GBIC Transceiver Caution: Install only 5 V GBIC transceivers into the module slots. You can install a GBIC transceiver as described below: 1. Insert the transceiver with the SC connector facing out toward you. Note that the transceiver is keyed so that it can only be installed in one orientation. 2.
Powering On the Switch Connecting to the Stack’s Backplane Plug one end of the provided stack cable in the “Down” port of the top unit and the other end to the “Up” port of the next unit. Repeat this step for each unit in the stack. Form a simple chain starting at the “Down” port on the top unit and ending at the “Up” port on the bottom unit (stacking up to 8 units).The VDSL Switch-VS2512A supports a wrap-around stacking feature.
Installing the VDSL Switch and Splitter 3. Check the front-panel LEDs as the switch is powered on to be sure the Power LED is lit. If not, check that the power cable is correctly plugged in. The switch will automatically select the setting that matches the connected input voltage. Therefore, no additional adjustments are necessary when connecting it to any input voltage within the range marked on the front panel. 4. The switch performs a self-diagnostic test upon power-on.
Chapter 4: Making Network Connections Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. For 100BASE-TX connections, Category 5 cable is required; for 10BASE-T, Category 3, 4 or 5 cable can be used. Cabling Guidelines The RJ-45 ports on the switch support automatic MDI/MDI-X operation, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
Making Network Connections .
Connecting to the Punch-down Blocks 2. Label the cables to simplify future troubleshooting.
Making Network Connections Caution: This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on. 1. Remove and keep the SC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics. 2. Check that the fiber terminators are clean.
Appendix A: Troubleshooting Diagnosing Switch Indicators The VDSL Switch-VS2512A can be easily monitored through panel indicators to identify problems.The table below describes common problems you may encounter and possible solutions. If the solutions in the table fail to resolve the problem contact Accton Technical Support for advice. Symptom POWER indicator does not light up after power on. Cause Power outlet, power cord, or internal power supply may be defective.
Troubleshooting Installation Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly. In-Band Access You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software such as AccView.

Cables 10BASE-T/100BASE-TX Pin Assignments For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for receiving data.
Twisted-Pair Cable and Pin Assignments 1000BASE-T Pin Assignments 1000BASE-T ports 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. The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.
Cables Adjusting Existing Category 5 Cabling to Run 1000BASE-T If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem: 1. Replace any Category 5 patch cables with high-performance Category 5e cables. 2. Reduce the number of connectors used in the link. 3. Reconnect some of the connectors in the link.
Console Port Pin Assignments Console Port Pin Assignments The DB-9 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The on-board menu-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following tables. Figure 2-1.
