A method includes identifying a first distributed conversion and control assembly (DCCA) in a central electronics complex (CEC) of a computer system, the CEC containing the first DCCA and a second DCCA, each of the first DCCA and the second DCCA having a flexible service processor (FSP); determining that the computer system satisfies preconditions for concurrent replacement of the first DCCA; disabling control software for a thermal and power management device (TPMD) of the first DCCA; fencing off the first DCCA; depowering the first DCCA; receiving a new media access control (MAC) address of a replacement DCCA; reconfiguring an operating system of the CEC to recognize the new MAC address of the replacement DCCA; powering on the replacement DCCA; removing the fencing off of the first DCCA; and resetting an FSP of the replacement DCCA.

An automated method and system are provided for facilitating monitoring of energy usage within a data center. The method includes automatically determining energy usage of one or more electronics racks of a data center by automatically ascertaining time-based energy usage of the electronics racks. The automatically ascertaining includes obtaining multiple measurements of instantaneous energy usage by each of the electronics racks in the data center over a period of time, and then separately averaging the multiple measurements for each electronics rack to obtain the time-based energy usage of each electronics racks. The method also includes outputting the time-based energy usage of the electronic(s) racks to facilitate monitoring of the data center.
