When connecting a PC to a switch with Auto MDI-X disabled, which UTP cable should be used?

To connect a PC to a switch when Auto MDI-X is disabled, a straight-through cable should be used. Straight-through cables are designed to connect different types of devices, such as a PC to a switch or hub. In this scenario, the PC's Ethernet interface and the switch's port require different wiring configurations for proper communication.

Typically, in a straight-through cable, the pinouts on both ends are the same (T568A or T568B), which is suitable for connecting a device like a PC to a network device like a switch. When Auto MDI-X is not available, the switch does not automatically adjust for the cable type, making it imperative to use the correct cable to ensure the devices can communicate effectively.

Crossover cables, on the other hand, are used to connect similar devices, such as connecting switch to switch or PC to PC directly. Twisted pair cable is a general term that encompasses both straight-through and crossover cables, and does not specify the correct application for connecting a PC to a switch. Rollover cables are primarily used for console connections to network devices, which is not applicable in this context. Thus, the straight-through cable is the appropriate choice for this connection scenario.
