step 1 use the blue rj-45-to-db-9 cable, or the blue rj-45 rollover cable and db-9 adapter, to connect the router to a terminal. (see figure 3-43 through figure 3-46.)
for information about cable pinouts, refer to the online publication cisco modular access router cable specifications available on cisco.com and on the documentation cd-rom.
on the cisco 3660 router, the console port is color-coded blue.
step 2 configure your terminal or terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.
because hardware flow control is not possible on the console port, cisco does not recommend that modems be connected to the console port. modems should only be connected to the auxiliary port.
