UPS
Under the UPS tab, you can modify UPS-related settings. UPS (Uninterruptible Power Supply) is a backup power
device that allows the DiskStation to continue operating for a short time if power failure occurs. This function
helps prevent data loss by giving the DiskStation enough time to save data and unmount volumes before losing
power and shutting off. DiskStation supports connecting to local or SNMP UPS devices.
Power Schedule
Click the Power Schedule tab to start up or shut down automatically at a specified time.
HDD Hibernation
Click the HDD Hibernation tab to manage disk hibernation for all internal or external disks on your DiskStation.
When a disk enters HDD hibernation mode, it will stop spinning and become inactive, which not only saves
energy but also extends the disk's lifespan.
