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.

The 10/100/1000 Ethernet ports on switches use RJ-45 connectors and Ethernet pinouts.
Figure B-1 10/100/1000 Port Pinouts
The 10-Gigabit Ethernet electrical modules use CX1 copper connectors similar to the one shown in Figure B-2.
Note When ordering or using CX1 cables, ensure that the version identifier is 2 or higher.
The 10-Gigabit Ethernet optical modules use the connectors shown in Figure B-3 and Figure B-4.
Figure B-2 10-Gigabit Ethernet CX1 Copper Connector (example)
Figure B-3, Figure B-4, and Figure B-5 show the SFP module connectors.
The Catalyst 3560-X switch supports the SFP module patch cable, a 0.5-meter, copper, passive cable with SFP module connectors at each end (Figure B-6). This cable can be used (only with 1-Gigabit Ethernet SFP ports) to connect two Catalyst 3560-X switches in a cascaded configuration.

The 10/100 Ethernet management port uses RJ-45 connectors with Ethernet pinouts. Figure B-7 shows the pinouts.
Figure B-7 10/100 Port Pinouts
The switch has two console ports: a USB 5-pin mini-Type B port on the front panel (see Figure B-8) and an RJ-45 console port on the rear panel.
Figure B-8 USB Mini-Type B Port
The USB console port uses a USB Type A to 5-pin mini-Type B cable, shown in Figure B-9. The USB Type A-to-USB mini-Type B cable is not supplied. You can order an accessory kit (part number 800-33434) that contains this cable.
Figure B-9 USB Type A-to-USB 5-Pin Mini-Type B Cable
The RJ-45 console port uses an 8-pin RJ-45 connector (See Table B-2 and Table B-3 .) The supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter. For console port and adapter pinout information, see Table B-2 and Table B-3 .
Each port must match the wave-length specifications on each end of the cable, and the cable must not exceed the stipulated cable length. Copper 1000BASE-T SFP module transceivers use standard four twisted-pair, Category 5 cable at lengths up to 328 feet (100 meters).

TYou can identify a crossover cable by comparing the two modular ends of the cable. Hold the cables side-by-side with the tab at the back. The first (far left) colored wire (pin 1) at one end of the cable is the third colored wire (pin 3) at the other end of the cable. The second colored wire (pin 2) at one end of the cable is the sixth colored wire (pin 6) at the other end of the cable. See Figure B-14.

The console port uses an 8-pin RJ-45 connector, which is described in Table B-2 and Table B-3 . If you did not order a console cable, you need to provide an RJ-45-to-DB-9 adapter cable to connect the switch console port to a PC console port. You need to provide an RF-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit with an adapter (part number ACS-DSBUASYN=). For console port and adapter pinout information, see Table B-2 and Table B-3 .
