Solution

To resolve the problem:
1. Verify that the system software image on the MPU is correct.
a. Log in to the MPU through the console port and restart the switch. If the system reports that a
CRC error occurs or that no system software image is available during the BootWare loading
process, reload the system software image.
b. Verify that the system software image in the flash memory is the same size as the one on the
server. If no system software image is available in the flash memory, or if the image size is
different from the one on the server, reload the system software image. Then set the reloaded
system software image to the current system software image.
The system software image in the flash memory is automatically set to the current system
software image during the BootWare loading process.
2. Verify that the MPU memory is running correctly.
Reboot the MPU, and immediately press CTRL+T to examine the memory. If a memory fault is
detected, replace the MPU.
3. Verify that no error is reported during the BootWare loading process.
If there are still errors reported during the BootWare loading process, identify the faulty module
and verify that the MPU is installed securely.
If the MPU is not installed securely, remove and reinstall the MPU.
