Appendix A Reference Connector Specifications Connector Specifications This section describes the connectors on the switch. • 10/100 and 10/100/1000 Ports, page A-5 • SFP Module Ports, page A-8 • Dual-Purpose Ports, page A-9 10/100 and 10/100/1000 Ports The 10/100 and 10/100/1000 Ethernet ports use standard RJ-45 connectors and Ethernet pinouts with internal crossovers.
Appendix A Reference Connector Specifications Figure A-4 shows the pinout for a 10/100/1000 port. Caution 10/100/1000 Port Pinouts Pin Label 1 TP0+ 2 TP0- 3 TP1+ 4 TP2+ 5 TP2- 6 TP1- 7 TP3+ 8 TP3- 1 2 3 4 5 6 7 8 60915 Figure A-4 PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Only standard-compliant cabling can be used to connect Cisco pre-standard IP Phones or wireless access points or IEEE 802.3af-compliant devices to PoE ports.
Appendix A Reference Connector Specifications You can the Cisco Configuration Assistant to enable the automatic medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly.
Appendix A Reference Connector Specifications SFP Module Ports The SFP module ports on the switch use fiber-optic SFP modules with LC connectors (Figure A-5) and copper SFP modules with RJ-45 connectors (Figure A-6). See the “Supported Hardware” section on page 1-14 for a list of supported SFP modules. Fiber-Optic SFP Module LC Connector 58476 Figure A-5 Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.
Appendix A Reference Connector Specifications Dual-Purpose Ports The Ethernet port on a dual-purpose port uses standard RJ-45 connectors. Figure A-7 shows the pinouts. The SFP module slot on a dual-purpose port uses SFP modules for fiber-optic and copper uplink ports. See the “Supported Hardware” section on page 1-14 for a list of supported SFP modules. The auto-MDIX feature is enabled by default. For configuration information for this feature, see the Cisco Configuration Assistant online help.
Appendix A Reference Cabling Guidelines Cabling Guidelines This section describes the cabling guidelines for the port connections. • Ethernet Port Connections, page A-10 • Small Form-Factor Pluggable Module Port Connections, page A-10 Ethernet Port Connections For copper Ethernet ports, cable lengths from the switch to connected devices must be within 328 feet (100 meters).
Appendix A Reference Cabling Guidelines Note Table A-2 When using shorter distances of single-mode fiber cable, you might need to insert an inline optical attenuator in the link to avoid overloading the receiver. Fiber-Optic SFP-Module Port Cabling Specifications SFP Module 100BASE-BX-10D Wavelength (nanometers) 1550 Modal Bandwidth (MHz/km) Cable Distance SMF G.652 2 — 32,810 ft (10 km) SMF G.
Appendix A Reference Cabling Guidelines For SMF connections, use one of the LCs listed in Table A-3 or Table A-4. For MMF connections, use one of the LCs listed in Table A-5. Use the Cisco part numbers to order the patch cables that you need, or order patch cables from your vendor.
Appendix A Reference Cable and Adapter Specifications Cable and Adapter Specifications These sections describe the cables and adapters used with the switch. • Two Twisted-Pair Cable Pinouts, page A-13 • Four Twisted-Pair Cable Pinouts for 1000BASE-T Ports, page A-14 • Crossover Cable, page A-15 Two Twisted-Pair Cable Pinouts Figure A-8 and Figure A-9 show the schematics of two twisted-pair cables for connecting to 10BASE-T- and 100BASE-TX-compatible devices.
Appendix A Reference Cable and Adapter Specifications Four Twisted-Pair Cable Pinouts for 1000BASE-T Ports Figure A-10 and Figure A-11 show the schematics of four twisted-pair cables for the 1000BASE-T SFP module ports on the switch.
Appendix A Reference Cable and Adapter Specifications Crossover Cable To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left plug should be a different color from the wire connected to the pin on the inside of the right plug. (See Figure A-12.) Figure A-12 Identifying a Crossover Cable Pin 1 on one connector and pin 1 on the other connector should be different colors.
