• Thunderbolt Receive Sleep Request
To the user, the system appears to be either on or off. There
are no other detectable states. However, the system sup-
ports multiple power states that correspond to the power
states defined in the Advanced Configuration and Power
Interface (ACPI) specification. ARC-8050T3U RAID storage
contains power On/Off controls on the controller. The Thun-
derbolt Receive Sleep Request function is used to define the
ARC-8050T3U power state based on the host computer power
state. The Thunderbolt Receive Sleep Request options are as
follows:
- Turn Power Off (original mode)
The power On/Off controls can turn ARC-8050T3U power in
unison with the host computer power state.
- Keep Power On for 10/20/40/60/90/120 minutes
or always on
The ARC-8050T3U keeps on the time frame of setting when
host computer enters sleep state (ACPI S1-S4 state). The
ARC-8050T3U automatically turns off itself when it receives
ACPI S5 state or is disconnected from host computer. Other-
wise you still need to power it off by press Reset Button on
the RAID storage.
