Thunderbolt 3 Cable Types and Performance for Pegasus32 Series

2024-10-29T02:07:59.6970000

The Pegasus32 series supports both Thunderbolt 3 and USB protocols and comes with a passive 0.7-meter Thunderbolt 3 cable. Below is a breakdown of how active vs. passive Thunderbolt 3 cables impact performance based on length:

Thunderbolt 3 Cable Length and Performance

✅ 0.7m to 1m cables

Always passive
Run at full speed (40Gbps for Thunderbolt 3)
No need for an active cable

✅ 2m cables

Can be active or passive
Active cables maintain full Thunderbolt 3 speed (40Gbps)
Passive cables allow reduced speeds (typically 20Gbps)

✅ Longer cables (>2m, fiber optic)

Fiber optic Thunderbolt 3 cables exist, but Promise has no official experience with them.

⚠️ Important Note

Active Thunderbolt 3 cables do not support USB 2 speeds (they are designed specifically for Thunderbolt performance).

Pegasus32 Fan and Power Management Guide

2024-10-29T02:00:23.1330000

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.
