Switch not booting up

We have a Catalyst 4506 Chassis (WS-C4506) with sup II+ engine running IOS 12.2(20)EW. After a power shutdown we noticed that the switch didnt come up. The SUP LED's were showing AMBER and other line cards were in RED state. In the console we noticed that the switch was booting in rommon mode. When we gave a command "boot" the switch booted with the flash IOS image and is working fine now. We need to make sure that this doesnt happen next time and to fix this issue.

Has anyone faced similar issue before. If anyone faced the issue, what was the fix for this.

the switch IOS image file is cat4000-i9k91s-mz.122-20.EW.bin

Any bugs on this image.

The configuration register on the switch is 0x2102 now. Is this fine. What is the default config register value in 4506 switches. Plz help me on this.


Re: Switch not booting up

With the info that is available we can only guess..

Would it be possible for you to reload the switch once again and capture the events?

I would also like to see the boot-section of the config, i.e. all "boot system" commands.
