Lists the port pinouts, module and cable connectors.
This section describes the connectors supported by Cisco C9350 series smart switches.
10/100/1000 Ports
This illustrations shows all 10/100/1000 ports including the PoE ports that use standard RJ-45 connectors and Ethernet pinouts

MPO-12 connectors
The multi-fiber push on (MPO) connector is used in high-density fiber optic networks. An MPO-12 connector has 12 fiber strands in a single connector that enables high-speed data transmission and efficient cable management. Its footprint is similar to the SC simplex connector. The MPO connector conforms to the TIA/EIA-604-5 intermateability standard. It is used for establishing 40G and 100G optical parallel connections.
The MPO connector conforms to the TIA/EIA-604-5 intermateability standard. It is used for establishing 40G and 100G optical parallel connections.
Key characteristics of MPO-12 connectors include
compatibility with various transceivers: Many Cisco transceivers use MPO-12 connectors for data transmission.
breakout cable support: MPO-12 connectors can be used in breakout cables.

Cable pinouts
A cable pinout refers to the specific arrangement of wires within a cable connector. Pinouts define how each pin is connected between the two ends of a cable.

Identify crossover cables
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.

Console port adapter pinouts
Use an RJ-45-to-DB-9 adapter cable to connect the switch console port to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter to connect the switch console port to a terminal.
