What if one DAE Power Supply Failed ?
Hi,
We are running CX4-240. From Unisphere, we get an error message "DAE (Bus 1 Enclosure 0) is faulted". And we discover that it is due to one Power Supply (Bus 1 Enclosure 0 Power A) is faulted.
We would like to know is there any affect if that power supply failed. Is there any power testing for that DAE being conducted ? If yes, how frequent ?
Thanks

Each DAE has two power supplies - each one is capable of supply power to the whole DAE - so if one fails the remaining DAE power supply will keep the drives powered. You do need to get the PS replaced. if the other PS fails, then you lose the whole DAE.

Hi Tony,
Now it runs on Standby Power Supply(SPB).If SPB also gets faulted then there will be an outage.
Thanks
