Abstract

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.
