What is uninterruptible power supply (UPS)?
Uninterruptible Power Supply (UPS) is a form of backup power supply device. When power is cut off, it allows the TNAS to enter the safe mode and stop all system services and unmount all volumes before it has to shut down, which protects the data.
What happens if power supply stops suddenly?
If power supply to devices stops because of an instantaneous voltage drop or a power failure, devices such as PCs or registers shut down abnormally, which can damage hard disks and corrupt the data. A UPS can help prevent such power supply problems.
What does a UPS protect against?
A UPS, or a uninterruptible power supply, is a device used to backup a power supply to prevent devices and systems from power supply problems, such as a power failure or lightning strikes. A UPS can help prevent power supply problems that can often occur on a production site, such as an instantaneous voltage drop and a power failure.
What happens if a TNAS device runs out of power?
If the UPS device runs out of power before the specified time, the TNAS device will enter safe mode immediately. Selecting the "Enable Auto Power On" option causes the TNAS to automatically power on when power is restored. USB UPS is a backup power supply device connected to the TNAS via an USB port.
What is a UPS and how does it work?
A UPS (uninterruptible power supply) is a device that provides backup power to prevent devices and systems from power supply problems like power failures or lightning strikes. It helps protect against issues such as instantaneous voltage drops and power failures that can occur on a production site.
What happens if a power supply is interrupted?
Depending on the device and the task being performed, even a brief interruption can lead to undesirable consequences such as defects or loss of data. Even with an uninterruptible power supply, some solutions may result in a short interruption of the power supply. However, this is only a few milliseconds.
