The Pegasus32 is designed to supply 85 Watts of charging power to connected devices, even when the host system is shut down or in sleep mode.
Because of this design:
- The power supply fan remains on to provide adequate cooling while delivering power.
- The main fan and hard drives are turned off to minimize noise during these states.
Eliminating Power Supply Fan Noise
Method 1: Shut Down Pegasus32 via the Power Button
- Eject the Volume:
- Before shutting down, eject the Pegasus32 volume properly from your system.
- Hold Power Button:
- Press and hold the power button for about 6 seconds (located on the front panel).
- Shutdown Complete:
- The Pegasus32 will power off completely and the fan noise will stop.
- Power On Again:
- To turn it back on, hold the power button for 6 seconds.
Method 2: Disconnect the Thunderbolt Cable
- Eject the Volume:
- Eject the Pegasus32 volume before unplugging any cables.
- Unplug Thunderbolt Cable:
- Disconnect the Thunderbolt cable either from the Pegasus32 or your computer.
- Fan Noise Stops:
- The Pegasus32 will stop supplying power, and the fan noise will stop.
- Reconnect Thunderbolt Cable:
- Reconnect the Thunderbolt cable when ready to use again.
Important Notes:
- Always eject the volume before disconnecting the Thunderbolt cable to prevent data loss.
- When using the power button shutdown, the Pegasus32 must be manually powered back on with the button—it won't automatically turn on when the system restarts.
- The power supply fan only operates in charging mode to prevent overheating, ensuring safe power delivery to your devices.
