I/O module faults are permanently recorded on the module's EEPROM. A module that has failed a

system health check cannot be brought back online.

If the faulty module is a master MSM, the slave MSM automatically becomes the master and sets the

faulty MSM to

. The new master MSM re-initializes and brings up all the I/O modules.

If the faulty module is a master MSM and there is no slave MSM, the system continues operation in a

"limited commands" mode. In the "limited commands" mode, the I/O slots are not initialized, and only

commands that do no affect the switch hardware configuration are allowed.

If the faulty module is a slave MSM, the fault is recorded in the slave's MSM's NVRAM and the slave

MSM is taken offline.

To view the failure messages, use the

command. This

clear log diag-status

command will clear the error messages from the MSM NVRAM. If the MSM failed a system health

check, this command restores the MSM to full functionality. This command should only be used for
