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. 10-Gigabit Ethernet CX1 Copper Connector (example) 278541 Figure B-2 SFP and SFP+ Modules 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.

USB Mini-Type B Port 253163 Figure B-8 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. USB Type A-to-USB 5-Pin Mini-Type B Cable 253405 Figure B-9 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.

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 or 1000BASE-LX/LH SFP modules and a short link distance can cause transceiver saturation and 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).

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.

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. Table B-2 lists the pinouts for the console port, the RF-45-to-DB-9 adapter cable, and the console device.
