Re: Brocade 300 + System will shut down within 2 minutes.

Hi Michalj,


in single user root mode, FOS, is not "active". Shutdown as you stated because of the temperature reported which is initiated via the FOS part.


It might be that one temperature sensor or all are bad, or there is enough interference on the i2c bus used for reading out value.


What about psshow - do you get correct value for both powersupplies?


Try to remove all SFPs (data is read via I2C), next step would be remove also one of the PS to further reduce the amount of the devices on the I2C bus. And then to upgrade.
