I have a campus environment where I have several buildings which all have EPN's. Some of the EPN's are center stage attached, but not all. Some are ipsi attached. Our building maintenance people are going to power down one of our buildings completely. The building that is being powered down has the center stage located in it. Our S8730 servers are not located in that building so they will remain powered up. My question is do I just power down the cabinet with the center stage before they turn the power off or do I need to power ALL the epn's off that connect to the center stage?
