The 100BASE-FX MM fiber-optic uplink ports operate in full-duplex mode.
You can connect a 100BASE-FX port to a port on a target device by using one of
the MT-RJ fiber-optic patch cables listed in
Table B-1 on page B-3 . Use the Cisco
part numbers in Table B-1 to order the patch cables that you need.

switch or any device on the network because an electrical arc can occur. This
could cause an explosion in hazardous location installations. Be sure that
power is removed from the switch and cannot be accidentally be turned on, or
verify that the area is nonhazardous before proceeding.
