GS504T.Manual.FINAL 6/2/00 12:49 PM Page 11 CHAPTER 2: PHYSICAL DESCRIPTION This chapter describes the hardware features of the NETGEAR Model GS504T Copper Gigabit Switch. Front Panel The front panel of the Model GS504T switch contains the following LEDs that correspond to each network port: Activity (Rx/Tx) and FDX/COL (full-duplex/collision). Each network port has its own link LED (located above each 100/1000 Mbps port).
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 12 LEDs Table 2-1 describes the activity of the LEDs. Table 2-1. LED Descriptions Label Color Activity Description Power Green On Power is supplied to the switch. Off Power is disconnected. Green On The port is operating in full-duplex mode. Off The port is operating in half-duplex mode. Yellow Blinking Data collisions are occurring on the port. In a full-duplex environment, there is no collision.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 13 CHAPTER 3: APPLICATIONS This chapter presents an overview of the levels of service provided by incorporating the technology of the NETGEAR Model GS504T Copper Gigabit Switch into your network. Desktop Switching Figure 3-1 illustrates the Model GS504T switch, used as a desktop switch to build a powerful network that enables users to have 1000 Mbps access to a file server.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 14 Segment Switching and Bridging from 100 Mbps to 1000 Mbps The Model GS504T switch, as illustrated in Figure 3-2, connects multiple power workgroups and servers using high-speed gigabit links. Each power workgroup is anchored by a NETGEAR Model FS510T switch. Because each copper link can be up to 100 m long, these workgroups can be located on separate floors or in different buildings.

GS504T.Manual.FINAL 6/2/00 12:49 PM Page 23 APPENDIX B: CONNECTOR PIN ASSIGNMENTS This appendix provides information about the RJ-45 plug and the RJ-45 connector used for the NETGEAR Model GS504T Copper Gigabit Switch. RJ-45 Plug and Vista RJ-45 Connector In a Fast Ethernet network, it is important that all 100BASE-T certified Category 5 cabling use RJ-45 plugs.The RJ-45 plug accepts 4-pair UTP or shielded twisted pair (STP) 100 ohm cable and connects into the vista RJ-45 connector.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 24 Table B-1 lists the pin assignments for the 10/100 Mbps RJ-45 plug and the vista RJ-45 connector. Table B-1.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 25 APPENDIX C: CABLING GUIDELINES This appendix provides specifications for cables used with the NETGEAR Model GS504T Copper Gigabit Switch. Fast Ethernet Cable Guidelines Fast Ethernet uses UTP cable, as specified in the IEEE 802.3u standard for 100BASE-TX.The specification requires Category 5 UTP cable consisting of either two-pair or four-pair twisted insulated copper conductors bound in a single plastic sheath.

GS504T.Manual.FINAL 6/2/00 12:49 PM Page 27 Twisted Pair Cables 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.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 28 Patch Panels and Cables If you are using patch panels, make sure that they meet the 100BASE-TX requirements. NETGEAR recommends Category 5 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. To wire patch panels, you need two Category 5 UTP cables with an RJ-45 plug at each end, as shown in Figure C-3.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 29 Using 1000BASE-T Gigabit Ethernet over Category 5 Cable Overview When using the new 1000BASE-T standard, the limitations of cable installations and the steps necessary to ensure optimum performance must be considered.The most important components in your cabling system are patch panel connections, twists of the pairs at connector transition points, the jacket around the twisted pair cable, bundling of multiple pairs on horizontal runs and punch down blocks.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 30 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. All four pairs of the twisted pair are used by 1000BASE-T, unlike 10BASE-T and 100BASE-TX, which use only two of the four pairs of wires within the Category 5.
GS504T.Manual.FINAL 6/2/00 12:49 PM Page 31 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/TIA568-A:1995 or ISO/IEC 11801:1995 Category 5 specifications.
