Standby Mode
The RAID enclosure features standby mode to help reduce noise and power consumption. When the RAID
enclosure enters standby mode, the system fan and installed HDDs stop spinning, and system processes are
paused. Upon waking, the RAID enclosure returns to the previous system state and any paused processes
are resumed.
The RAID enclosure enters standby mode under the following conditions:
• The host enters hibernation or standby mode or is powered off.
The RAID enclosure only enters standby mode if the USB power design of the host supports this
feature.
• The USB cable is disconnected.
Note
The TR-002 will not enter standby mode during RAID rebuilding. If prompted to enter
standby mode during RAID rebuilding, the TR-002 will finish RAID rebuilding before
entering standby mode.
