Smart Carriers HPE Hard Drives with smart carriers are designed to provide an interface to communicate critical status and management information. System status LED icons and a spinning activity ring reflecting the data-writing process notify users of the current system status. A blue LED located behind the handle can be activated remotely to guide users to a specific drive tray while a do-not-remove icon positioned on the tray\'s eject button lights up to warn users when the removal of the drive would cause data loss.  . .
