4. Close the front panel of the enclosure.

4.2. Setting RAID Mode

The Yottamaster DR2RU3-25 supports multiple RAID modes configured via DIP switches on the rear of the enclosure. Always ensure the enclosure is powered off before changing RAID mode settings.

1. Locate the DIP switches on the rear panel of the enclosure.
2. Refer to the diagram below to set the desired RAID mode.
3. After setting the DIP switches, power on the enclosure.
4. مهم: After changing the RAID mode, you must initialize and format the drives on your computer. This process will erase all existing data on the drives. Back up any important data before proceeding.

5. تعليمات التشغيل

5.1. الاتصال بجهاز الكمبيوتر الخاص بك

1. Connect the USB 3.0 Type-B end of the data cable to the corresponding port on the rear of the enclosure.
2. Connect the USB 3.0 Type-A end of the data cable to an available USB port on your computer.
3. Connect the 5V 2A power adapter to the DC input port on the enclosure, then plug the adapter into a power outlet.

4. Press the power button on the enclosure to turn it on. The LED indicator will illuminate.
5. Your computer should detect the new hardware. For new drives or after changing RAID modes, you may need to initialize and format the drives through your operating system's Disk Management utility (Windows) or Disk Utility (macOS).

5.2. Auto-Sleep Function

The enclosure features an auto-sleep function. If there is no data exchange or activity for approximately 10 minutes, the hard drives will enter sleep mode. This helps to save power and prolong the lifespan of your drives. The drives will automatically wake up when data access is requested.

6. RAID Mode Configuration Details

Understanding the different RAID modes is crucial for optimal data management. Remember to power off the enclosure before adjusting DIP switches and re-initialize/format drives after any change.

Figure 6.1: RAID Mode Comparison

• PM (Individual Mode): Each installed drive is recognized as a separate, independent volume by the operating system. This mode offers no data redundancy or performance enhancement.
• RAID 0 (التوزيع): Data is split into blocks and written across both drives. This mode offers the highest read/write speeds and combines the capacity of both drives. Warning: If one drive fails, all data on both drives will be lost.
• ريد 1 (النسخ المتطابق): Data is simultaneously written to both drives, creating an exact copy. This mode provides excellent data redundancy; if one drive fails, your data is still accessible on the other. The total usable capacity is limited to that of the smaller drive.
• SPAN (JBOD - مجرد مجموعة من الأقراص): Drives are concatenated to form one large logical volume. Data is written sequentially to the first drive until it's full, then to the second. This mode offers combined capacity but no performance improvement or data redundancy. Warning: If one drive fails, data on both drives may be lost.

7. الصيانة

• تنظيف: استخدم قطعة قماش ناعمة وجافة لتنظيف الجزء الخارجي من الحاوية. تجنب استخدام المنظفات السائلة أو المواد الكاشطة.
• تهوية: Ensure the cooling holes on the enclosure are not obstructed to maintain proper airflow and heat dissipation.
• الاغلاق الصحيح: Always safely eject or unmount the drives from your operating system before powering off the enclosure or disconnecting the USB cable to prevent data corruption.
• تحديثات البرامج الثابتة: Check the Yottamaster official webقم بزيارة الموقع بشكل دوري للحصول على أي تحديثات البرامج الثابتة المتوفرة للطراز الخاص بك.

8. استكشاف الأخطاء وإصلاحها

المشاكل الشائعة والحلول:

• لم يتم اكتشاف الحاوية بواسطة الكمبيوتر:
  • تأكد من توصيل كابل USB بشكل آمن بكل من العلبة والكمبيوتر.
  • Verify the power adapter is properly connected and the enclosure is powered on.
  • جرب منفذ USB مختلفًا على جهاز الكمبيوتر الخاص بك أو كابل USB مختلفًا.
• Drives not appearing in 'My Computer' or 'Finder':
  • For new drives or after changing RAID modes, drives need to be initialized and formatted. Access Disk Management (Windows) or Disk Utility (macOS) to perform these actions.
  • Ensure drives are correctly installed in the enclosure bays.
  • Check the RAID mode settings via the DIP switches.
• سرعات نقل بطيئة:
  • تأكد من توصيل جهازك بمنفذ USB 3.0.
  • Verify your drives are healthy and not experiencing issues.
  • Check if UASP is enabled by your operating system and drivers.
• RAID mode not functioning as expected:
  • Power off the enclosure. Double-check the DIP switch settings against the manual's diagram.
  • Power on the enclosure and re-initialize/format the drives.
  • Ensure both drives are of similar capacity and type for optimal RAID performance.
