Chapter 3 Installing the Router
IOS Software Configuration for the Router
Overview of the Boot Process
The example below assumes that the router is plugged into a power source and the router is running, blower module fans are audible, and alarm card ENABLED LEDs are lit up.
The following is an example of a typical boot process:
•The RP MBus module receives the correct DC voltage and starts executing MBus software.
•The RP determines the router configuration by sending a message via the alarm card requesting all installed devices to identify themselves. Their responses provide slot numbers and card and component types. The RP, line cards, CSCs, and SFCs are then powered up.
•The
•After the
•If the ROM monitor is configured to autoboot, it automatically loads and boots the Cisco IOS software.
•If the ROM monitor is not configured to autoboot, boot the Cisco IOS software manually. See the “Manually Booting the System” section on page
•When the Cisco IOS software boots, it polls all other cards in the system, powers them up, and loads the Cisco IOS software they require.
Starting the Router and Observing Initial Conditions
Observe the following conditions the first time you start your router:
•Power cables to the PDU are fully connected to both the PDU and the power source, and are secured with appropriate strain relief.
•Empty card slots or card bays are filled with card blanks. This ensures proper air flow through the chassis and electromagnetic compatibility (EMC).
•All cards are fully inserted in their cages and bays.
•All captive screws are tightened.
