Console Port
The console port uses an 8-pin RJ-45 connector, which is described in Table B-2 and Table B-3. The
supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch to a console PC.
You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console
port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from
Cisco. For console port and adapter pinout information, see Table B-2 and Table B-3.
Cable and Adapter Specifications
These sections describe the cables and adapters used with Catalyst 2960 switches:
• SFP Module Cable Specifications, page B-4
• Two Twisted-Pair Cable Pinouts, page B-6
• Four Twisted-Pair Cable Pinouts for 1000BASE-T Ports, page B-6
• Crossover Cable and Adapter Pinouts, page B-7
SFP Module Cable Specifications
Table B-1 lists the cable specifications for the fiber-optic SFP module connections. Each port must
match the wave-length specifications on the other end of the cable, and for reliable communications, the
cable must not exceed the required cable length. Copper 1000BASE-T SFP transceivers use standard
four twisted-pair, Category 5 or greater cable at lengths up to 328 feet (100 meters).
