Each port must match the
wave-length 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.
