Checklist for Power Up
You are ready to power up the Cisco 3800 series router after the following steps are completed:
• Chassis is securely mounted and grounded. (See the "Install Chassis" section on page 5.)
• Power and interface cables are connected. (See the "Connect Cables" section on page 16.)
• PC with HyperTerminal or similar terminal emulation program is connected to the console port, powered up, and
configured for 9600 baud, 8 data bits, 1 stop bit, no flow control, and no parity. (See the "Power Connections" section on
page 17.)
• Suitable PC COM port is selected in the terminal emulation program.
• You have selected passwords for access control.
• You have determined the IP addresses for the Ethernet and serial interfaces.
Note
For initial power-up, a direct console connection is recommended. After the initial configuration is completed, a remote
modem connection can be used for router management.
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
procedure is finished, the Cisco router is ready to configure.
To view the boot sequence, you must have a console connection to the Cisco router before it powers up.
Note
Make sure that your PC is powered up and connected as described in the "Checklist for Power Up" section on page 26.
