The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This appendix describes the Catalyst 3560 switch ports and the cables and adapters that you use to connect the switch to other devices and includes these sections:
•"Connector Specifications" section
•"Cable and Adapter Specifications" section
The 10/100 and 10/100/1000 Ethernet ports use standard RJ-45 connectors and Ethernet pinouts with internal crossovers. These ports have the send (TD) and receive (RD) signals internally crossed so that a twisted-pair straight-through cable and adapter can be attached to the port. Figure B-1 shows the pinout for a 10/100 port.
Figure B-1 10/100 Port Pinouts
Figure B-2 shows the pinout for a 10/100/1000 port.
Figure B-2 10/100/1000 Port Pinouts
The Catalyst 3560 switch uses SFP modules for fiber-optic and copper uplinks. See the Catalyst 3560 release notes for a list of supported SFP modules.
Figure B-3 Fiber-Optic SFP Module LC Connector
Figure B-4 Copper SFP Module RJ-45 Connector
The Ethernet port on a dual-purpose port uses standard RJ-45 connectors. Figure B-5 shows the pinouts.
Figure B-5 10/100/1000 Port Pinouts
The SFP module slot on a dual-purpose port uses SFP modules for fiber-optic and copper uplink ports. See the Catalyst 3560 release notes for a list of supported SFP modules.
Note The auto-MDIX feature is enabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference.
The console port uses an 8-pin RJ-45 connector, described in Table B-2 and Table B-3. The RJ-45-to-DB-9 adapter cable connects the console port of the switch to a console PC. You need an RJ-45-to-DB-25 female DTE adapter (ACS-DSBUASYN=) to connect the switch console port to a terminal. For console port and adapter pinout information, see Table B-2 and Table B-3.
•SFP Module Cable Specifications
•Two Twisted-Pair Cable Pinouts
•Four Twisted-Pair Cable Pinouts for 1000BASE-T Ports
•Identifying a Crossover Cable
Table B-1 lists the cable specifications for the fiber-optic SFP module connections. Each port must match the wave-length specifications on the other end of the cable, and for reliable communications, the cable must not exceed the required cable length. Copper 1000BASE-T SFP transceivers use standard four twisted-pair, Category 5 or greater cable at lengths up to 328 feet (100 meters).

1 Modal bandwidth applies only to multimode fiber. 2 A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers 3 A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m). 4 1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on the fiber quality, the number of splices, and the connectors. |

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 B-10.)

Table B-2 lists the pinouts for the console port, the RJ-45-to-DB-9 adapter cable, and the console device.
Table B-3 lists the pinouts for the console port, RJ-45-to-DB-25 female DTE adapter, and the console device.
Note You can order an RJ-45-to-DB-25 female DTE adapter, which is not supplied with the switch (ACS-DSBUASYN=).
