Removing/Replacing a Drive in the Enclosure - Pegasus R12

2024-11-15T15:43:11.4930000

To replace a physical drive:

1. Slide the top cover of the enclosure toward the front of the device.

2. Lift the cover to expose the hard disk drives.

3.To remove a drive carrier, firmly grasp the handle and slide the carrier upward to fully remove the drive and carrier assembly. Each hard disk drive is secured to the carrier with four screws designed for this purpose. Remove the screws, replace the faulty hard disk with a new one of the same type and size, and secure it with the screws.

4. To replace the hard disk drive and carrier assembly, insert them in the same orientation as when they were removed. Slide the assembly in until it is firmly seated. The drive stays securely in place without any additional hardware, such as a latch, as it fits snugly into position.

5. To replace the top of the enclosure, follow the removal procedure in reverse. Slide the top toward the back of the device until it snaps into place. The new drive is now ready for use.

Removing/Replacing a Drive in the Disk Carrier - Pegasus R12

2024-10-31T15:06:27.7770000

The Pegasus R12 arrives with all HDDs pre-installed in their carriers and securely seated in the enclosure. If an HDD needs replacement, follow these instructions to safely remove and replace the HDD within its carrier.

Important Notes:
- Use Identical Replacement Drives: Ensure the replacement HDD is the same model as the one being replaced. For the best performance and compatibility, all HDDs in the enclosure should match in model and type.

Steps to Replace an HDD in a Disk Carrier

Removing the HDD from the Disk Carrier:
1. Position the Assembly: Place the HDD and disk carrier assembly on a stable, secure surface (e.g., a table).

2. Unscrew the HDD: Remove the four screws securing the HDD in the carrier.
3. Detach the HDD: Carefully lift the carrier off the HDD without twisting or bending it.

Installing the New HDD in the Carrier:
1. Insert the New HDD: Place the new HDD (of the same type) into the carrier, aligning it properly.
2. Secure the Screws: Reinsert and tighten the four screws to secure the new HDD within the carrier.
3. Orient the Carrier Correctly: Ensure the handle on the carrier is positioned at the top of the HDD, while the bottom, where the SATA and power connectors are located, faces downwards to align with the enclosure’s SATA ports.

This orientation allows the connectors to engage properly, ensuring reliable contact and power transfer for the new drive.

Maintaining Proper Airflow for Pegasus R12

2024-10-31T15:00:12.1800000

To prevent overheating and ensure optimal performance of the Pegasus R12, it's essential to maintain proper ventilation around the device.

Key Guidelines:
- Clear Ventilation: Ensure that the air intake (top) and exhaust vents (bottom) are unobstructed, as blocking airflow may cause the system to overheat.
- Fan Functionality: The cooling fans pull cool air in through the top of the enclosure and expel heated air through the bottom. Keeping these areas clear allows the fans to regulate internal temperatures effectively.

- Secure HDDs and Top Cover: Confirm that all HDDs are properly seated and that the top cover is securely in place to maintain both airflow efficiency and protection of internal components.

Following these steps helps to prevent potential thermal issues, extending the lifespan and reliability of your Pegasus R12.

Thunderbolt Connection and Sleep Mode Behavior for Pegasus R12

2024-10-31T14:55:14.5670000

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.

How to Safely Shut Down the Pegasus R12

2024-10-31T14:50:41.4100000

Before proceeding with shutdown, always eject or dismount the connected Pegasus R12 volume(s). This ensures data integrity and safe power-down of the storage system.

Option 1: Using PROMISE Utility Pro

1. Open PROMISE Utility Pro.

2. Go to the Controls menu and click on the Device.

3. Click the Power Button icon and select Shut down the device.

4. A warning dialog will appear to prevent accidental shutdown. If your Pegasus R12 is part of a daisy chain (connected via Thunderbolt to other devices), those devices will also shut down.

5. Wait a few minutes for the shutdown process to complete. The Power Button LED on the front will light red during shutdown. Once the LED is off, you can safely disconnect the power cord.

Option 2: Using the Power Button

1. Eject or dismount the connected Pegasus R12 volume(s) first.
- On Mac, drag the volume icon into the Trash/Eject symbol, or right-click and choose Eject.
2. Touch and hold the Power Button on the device for about four seconds.
3. The shutdown process will begin, lighting the Power Button LED red during shutdown. Any devices connected via Thunderbolt behind the R12 will also enter shutdown mode.
4. Once the LED turns off, it’s safe to disconnect the power cord if needed.

Important: Always eject or dismount connected volumes before shutting down to prevent data loss or corruption.
