10 Gigabit Ethernet CX1 (SFP+ Copper) Connectors
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.

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.

Console Port
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
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
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.

SFP and SFP+ Module Cable Specifications
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).

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 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).

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.

Identifying a Crossover Cable
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.

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