Maybe, but Cisco is known for having a "special" pinout.
Best bet is to get a build-it-yourself RJ45 to DB9F adaptor - about
US$2.90, and the associated pin pusher - cause you'll mess up a
few times.
you;ll need to figure out which pins are transmit and receive - 2, and 3 on the
DB9
side. Also, note that different brands of RJ45 to DB9F connectors have
different color codes for the wires. Typically you'll use 5 of the 8 wires, so
best to
create a map on paper. There is supposed to be the Yost standard, but certain
folks do violate it at times - Cisco, Dell, etc. So you need to know the RS232
pinout
of your system.
Here are some pretty decent resources -
