PRP Boot Process

The following sequence describes a typical PRP boot process:

1.System power is turned on.

2.MBus module receives +5 VDC and starts executing MBus software.

3.PRP determines the system configuration by sending a message over the MBus requesting all installed devices to identify themselves. The return response provides slot number, and card and component type. The PRP, line cards, and clock scheduler cards (CSCs) are then powered up.

4.PRP power-on-reset logic delay, which allows power and both local and CSC clocks to stabilize.

5.After the power-on reset is released, the PRP begins to execute the ROM monitor software.

6.If the ROM monitor is configured to autoboot, it loads and boots the Cisco IOS software.

or

If the ROM monitor is not configured to autoboot, you must enter the appropriate b command at the ROM monitor prompt (Rommon>) to boot the Cisco IOS software.

7.When the Cisco IOS software boots, it polls all other cards in the system and powers them up, loading their Cisco IOS software as needed.
