Power-Up Procedure
To power up your Cisco router and verify that it goes through its initialization and self-test, follow this
procedure. When the procedure is finished, the Cisco router is ready to configure.
If you encounter problems when you power up the router, see
Appendix A, “Troubleshooting.”
For
information about the ROM monitor and the bootstrap program, see
Appendix B, “Using the
ROM Monitor.”
For information about the configuration register, see
Appendix C, “Configuration
Register.”
Note
To view the boot sequence through a terminal session, you must have a console connection to the
Cisco router
before
it powers up.
Step 1
Make sure that your PC is powered up and connected as described in the
“Checklist for Power Up”
section on page 3-26
.
Step 2
Move the power switch to the ON position.
Note
Cisco 3745 routers may have one or two chassis power supplies. A router may operate with
either power supply or with both power supplies in use. Two power supplies provide redundancy.
