10/100/1000 Ports
The 10/100/1000 Ethernet ports on switches use RJ-45 connectors and Ethernet pinouts.
Figure B-1 10/100/1000 Port Pinouts
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
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)
SFP and SFP+ Modules
Figure B-3, Figure B-4, and Figure B-5 show the SFP module connectors.
The 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 3850 switches in a cascaded configuration.

10/100/1000 Ethernet Management Port
The 10/100/1000 Ethernet management port uses RJ-45 connectors with Ethernet pinouts. Figure B-7 shows the pinouts.
Figure B-7 10/100 Port Pinouts
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 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.

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
To identify a crossover 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 the same color as the wire connected to the pin on the outside of the right plug. (See Figure B-14.)
Figure B-14 Identifying a Crossover Cable
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.
Table B-3 lists the pinouts for the console port, RJ-45-to-DB-25 female DTE adapter, and the console device.
