HI Nickolas, [Pls Rate if HELPS]

Please share the tech-support or show stacks and show version command output

to have the Stack Decoder analyze any crashes that might have occurred. Otherwise, replace the appropriate component after a second failure.

Explanation: This error message indicates a Hardware problem in the device.

Recommended Action: To troubleshoot try this:

1. Reload the device with no modules installed and check if the message appears.

2. Reload the device with each successive module and check to see if a certain module or mis-seated module is causing this issue.

Hope I am Informative.

Pls RATE if HELPS

Best Regards,

Guru Prasad R

Hi ,

First remove all the modules from slots and try to boot the router.

If you face same problem after removing all the modules , then try to upgrade the IOS.

Thanks,

Satish

Thanks man,

This worked,the router has four e1 cards,i tried each card step by step and finally i was able to boot well with the card in slot3 out,so does this mean that this E1 card is having some fault,Please help because i have just bought this card recently.

Once again thanks for your advice.

Hi,

This is what I found on cisco.com -

The error message relates to the bus error. The bus error can happen either due to the hardware modules problem or due to the router chassis problem.

Complete these steps in order to isolate the issue:

Power down the router.

Remove all network modules and power back on the router.

Power up the router.

If the router goes back into a boot loop with the error message, the chassis might be defective.

If the router boots normally, power down the router, install one network module, and power back up.

Continue to install one network module at a time because the hardware causes the issue. This should be done until the network module or chassis slot is isolated.

Replace the part determined to be defective.

If the router does not go back into the boot loop mode after you reinstall all modules, the issue might be a mis-seated network module.
