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 15.)
• 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 16.)
• 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.
