To better understand your problem you need to connect to the switch thru console n capture all the boot process log and upload here. It will help the Pros to analyze the problem.

Thank u aijaz,

But the switch reboot every 3 min....

How to capture the boot sequence if this is the case?

I can use console and Hyper terminal to enter switch configurations...later how to capture the boot sequence ?

lookin forward to c ur reply,

Hi Sakthi

If you have your laptop/PC connected to the console port of the switch with a hyper terminal window open, you should see the boot messages come up on the screen every time the switch reboots.

Just capture these messages while the switch is booting and post them here along with the output of show run if you can.

Best Regards,

In the hyper terminal menu/ Transfer /Capture Text, select a new text file here/then click start...it will capture all the data till you stop it. Then you can upload the text file here.

AFAIK this is related to the hardware/data bus problem. You need to check with your vendor.

Lets also wait for experts advice..
