6 Power Up the Router

Caution To ensure adequate cooling, never operate the router unless the cover and all modules and cover plates are installed.

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.

Note To view the boot sequence, 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 26.

Step 2 Move the power switch to the ON position on the router. The SYS LED blinks green on both the Cisco 3825 and Cisco

3845 routers. During the boot process, the SYS PWR LED on the Cisco 3825 chassis is steady green, and the SYS PWR1

LED or SYS PWR2 LED on the Cisco 3845 chassis are off. If this does not happen, see the “Troubleshooting” document
