Your PC terminal emulation program is configured for 9600 baud, 8 data bits, 1 stop bit, and no parity.

You have selected passwords for access control.

Power-Up Procedure
To power up your Cisco router and verify that it goes through its initialization and self-test, perform this procedure. When the
power-up procedure is finished, the Cisco router is ready to be configured.
Note
To view the boot sequence through a terminal session, you must have a console connection to the Cisco router before
it powers on.
Step 1
Make sure that your PC is powered up and connected as described in the “Checklist for Power-Up” section.
Step 2
Move the power switch to the ON position. The fan operates, and the SYS PS LED is continuous green for each power
supply that is in use. The SYS LED blinks while the system boots, and it is continuous green after the system boots. If
this does not happen, see the power-on procedure in the
Cisco 3700 Series Hardware Installation Guide
.
Note
If no Cisco IOS image is loaded on the Cisco 3745, the router enters ROMMON mode, and the system LED blinks.
