Removing and replacing an energy pack

This server supports the installation of a centralized backup power source option to back up write cache content on P-class HPE Smart Array controllers in case of an unplanned server power outage. Use this procedure to remove and replace either the HPE Smart Storage battery or the HPE Smart Storage Hybrid Capacitor.
