100BASE-FX Ports
The 100BASE-FX ports use MT-RJ connectors, as shown in Figure B-3. The
100BASE-FX ports use 50/125- or 62.5/125-micron multimode fiber-optic
cabling.
You can connect a 100BASE-FX port to an SC or ST port on a target device by
using one of the MT-RJ fiber-optic patch cables listed in Table B-1. Use the Cisco
part numbers in Table B-1 to order the patch cables that you need.

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. For console port and adapter pinout
information, see Table B-2 and Table B-3.
