The issue is caused by defective hardware or a mis-seated network module.
If the router is in boot loop mode and displays this error message, perform these steps:
- Power down the router.
- Remove all network modules and power the router back on.
- Power up the router.
- If the router goes back into a boot loop with the error message, the chassis may be defective.
- If the router boots normally, power down the router, install one network module, and power back up.
Continue installing one network module at a time because the hardware is causing 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 reinstalling all modules, the issue may be a mis-seated network module.
