    CHAPTER 2: PHYSICAL DESCRIPTION This chapter describes the hardware features of the NETGEAR Model GS516T Copper Gigabit Switch. Front Panel The front panel of the Model GS516T switch contains the following LEDs that corre- spond to each network port: FDX/COL (full-duplex/collision), Activity(RX/TX)/10Mbps .

  • Page 12: Auto-Uplink

    RJ-45 Ports The Model GS516T switch has 16 auto-sensing 10/100/1000 Mbps UTP ports. Each port can operate at 1000 Mbps full-duplex mode, 100 Mbps full/half duplex mode, or 10Mbps full/half duplex mode, and provide a standard UTP for Category 5 or Category 5e cable.

  • Page 13: Figure 2-3. Warning! Creating Loops Disables Your Network

    " Note: Using Auto Uplink to create multiple active paths between any two network devices can cause undesirable loops in the network, resulting in an endless broadcast traffic that disables your network. Loops occur when there are alternate routes between two network devices. In Figure 2-3, for example, a loop is created by con- necting two RJ-45 ports on a GS516T Switch to a router containing a 4-port switch.

    LEDs Table 2-1 describes the activity of the LEDs. Table 2-1. LED Descriptions Label Color Activity Description Power Green Power is supplied to the switch. Power is disconnected. FDX/COL Green The port is operating in full-duplex mode. The port is operating in half-duplex mode. Yellow Blinking Data collisions are occurring on the port.

  • Page 28: Return Loss

    Return Loss Return loss measures the amount of reflected signal energy resulting from impedance changes in the cabling link.The nature of 1000BASE-T renders this measurement very important; if too much energy is reflected back on to the receiver, the device will not perform optimally.

  • Page 29: Patch Cables

    Patch Cables When installing your equipment, replace old patch panel cables that do not meet Category 5e specifications. As pointed out in the NEXT section, this near end piece of cable is critical for successful operation. Conclusions For optimum performance of your 1000BASE-T product, it is important to fully qualify your cable installation and ensure it meets or exceeds ANSI/EIA/TIA- 568-A:1995 or ISO/IEC 11801:1995 Category 5 specifications.

    Category 5 Cable Category 5 distributed cable that meets ANSI/EIA/TIA-568-A building wiring standards can be a maximum of 328 feet (ft) or 100 meters (m) in length, divided as follows: • 20 ft (6 m) between the hub or switch and the patch panel (if used) •...

  • Page 31: Twisted Pair Cables For 1000Base-Tx

    Twisted Pair Cables for 100 BASE-TX For two devices to communicate, the transmitter of each device must be connected to the receiver of the other device.The crossover function is usually implemented internally as part of the circuitry in the device. Computers and workstation adapter cards are usually media-dependent interface ports, called MDI or uplink ports.

  • Page 32: Patch Panel And Cables

    If you are using patch panels, make sure that they meet the 100BASE-TX require- ments. NETGEAR recommends Category 5e UTP cable for all patch cables and work area cables to ensure that your UTP patch cable rating meets or exceeds the distribution cable rating.
