When the Thunderbolt connection to the Pegasus R12 is interrupted—either by powering off or restarting the connected Mac, or physically disconnecting the Thunderbolt cable—the Pegasus R12 will enter sleep mode rather than a complete shutdown.
This means the Pegasus R12 remains powered on but in a low-power state, ready to quickly resume operation when the Thunderbolt connection is restored.
Important Points
Interruption scenarios: The Pegasus R12 will enter sleep mode in the following cases:
- The connected Mac is powered off or restarted.
- The Thunderbolt cable is disconnected from the Pegasus R12.
- Not a complete shutdown: Entering sleep mode does not fully power down the device. To fully shut down the Pegasus R12, follow the shutdown procedures using either PROMISE Utility Pro or the Power Button as described here.
Note: Always ensure volumes are ejected or dismounted properly before disconnecting the Thunderbolt connection to avoid data issues.
