The following sections provide information about the various cables and adapters.
For cabling specifications, see Cisco SFP and SFP+ Transceiver Module Installation Notes.
Each port must match the wavelength specifications on the other end of the cable, and the cable must not exceed the stipulated length. Copper 1000BASE-T SFP module transceivers use standard four twisted-pair, Category 5 cable of lengths up to 328 feet (100 meters).
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 must provide a RJ-45-to-DB-25 female DTE adapter to connect the switch console port to a terminal.
