Cisco Catalyst 2960-X and 2960-XR Switches now support QSFP-4X10G-AOC5M, the 40GQSFP to four 10G SFP+ direct attach breakout
Active Optical cable assembly.
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).
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.
