3 MAKING NETWORK CONNECTIONS CONNECTING NETWORK DEVICES This switch is designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to devices using optional SFP tranceivers. TWISTED-PAIR DEVICES Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
CHAPTER 3 | Making Network Connections Twisted-Pair Devices CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 14: Making Twisted-Pair Connections 2. If the device is a PC card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See "Network Wiring Connections" on page 45.
CHAPTER 3 | Making Network Connections Twisted-Pair Devices NETWORK WIRING CONNECTIONS Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows. 1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel. 2.
CHAPTER 3 | Making Network Connections Fiber Optic SFP Devices FIBER OPTIC SFP DEVICES An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, or 1000BASE-LH) can be used for a backbone connection between switches, or for connecting to a high-speed server. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends.
CHAPTER 3 | Making Network Connections Connectivity Rules Figure 16: Making Fiber Port Connections 4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid. The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control.
CHAPTER 3 | Making Network Connections Connectivity Rules Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3ab standards.

APPENDIX A | Troubleshooting Power and Cooling Problems POWER AND COOLING PROBLEMS If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet. If you still cannot isolate the problem, then the internal power supply may be defective.
B CABLES TWISTED-PAIR CABLE AND PIN ASSIGNMENTS For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. CAUTION: DO NOT plug a phone jack connector into any RJ-45 port.
APPENDIX B | Cables Twisted-Pair Cable and Pin Assignments 10BASE-T/100BASE-TX PIN ASSIGNMENTS Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

APPENDIX B | Cables Twisted-Pair Cable and Pin Assignments 1000BASE-T PIN ASSIGNMENTS All 1000BASE-T ports 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.
APPENDIX B | Cables Fiber Standards 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 or Category 6 cables. 2. Reduce the number of connectors used in the link. 3. Reconnect some of the connectors in the link.
