Console Cables


Switch Name	Supported Console Cable
Cisco Catalyst 9500X Series Switches	USB Type A to Type C (CAB-USBC-4M-GR)

The USB console port uses a USB Type A to Type C cable. These cables are not supplied with the switch; you have to order them separately.

The USB-C console port uses a USB Type A to Type C cable for console connections.

Cables and Adapters

Transceiver Module Network Cables

For cabling specifications, refer to the following notes:

Each port must match the wavelength specifications on the other 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).

Identifying a Crossover Cable

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

The RS-232 console port uses an 8-pin RJ-45 connector. 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.
