3. Hardware Requirements and Precautions
1. After the hard disk is formatted, the actual total capacity of the ST2-B31+ detected by the
computer operating system will vary from the sum of all hard disk capacities stated by the
manufacturer.
2. To prevent data loss, do not remove ST2-B31+ while the system is running.
3. Please always connect the USB cable to the computer to ensure the energy saving function
operating normally.
4. Once the system has been initialized, do not switch hard disks around during use. Doing so may
prevent the RAID from being recognized by the system.
5. Once RAID mode has been set up, the switching of hard drives will lead to the removal of data
from the hard disks. Please be sure to backup the data on the hard disk before making any
switches.
6. The product needs to be restarted after adding or changing the RAID mode, and the update is
guaranteed to be the new RAID mode.
7. When the Notebook which support USB PD function is only connected to iST2-B31+, ST2-B31+
can provide up to 24W (12V/2A) power supply, but if then connected to other power supply such
like the original Notebook power supply, Notebook will automatically judge which one will be
the main power source, usually the one which can provide more Wattage will be. At this time,
ST2-B31+ may be interrupted and re-identied by the Notebook. Therefore, before connecting to
other power supplies, please make sure that there are no data accessed between Notebook and
ST2-B31+.
8. ST2-B31+ can only provide 24W at most, which is different from the original Notebook power
supply. It mainly to extend the Notebook's usage time. Take Macbook Pro 13" as an example,
the original power supply is 60W, assuming it take 2 hours for it to fully charge the battery , use
ST2-B31+ might need three times time. Therefore, if user need to use Notebook for a long time, it
is recommended to connect the original power supply rst before connect ST2-B31+.

Step 6
After installing two HDDs into Trays, please insert them into ST2-B31+, and then latch the
handle.
Please set RAID mode at the back-plate of ST2-B31+ unit for RAID 1, RAID 0, JBOD, and
BIG.
Please connect the signal cable rst, and then power cord later.
After completing hardware installation, turn on the power and follow the instruction of Disk
Utility to format the two HDDs, you then could start using your new ST2-B31+.

5. RAID Mode Setting
Provide a big storage capacity and the data transfer efficiency, but no data
porotection feature.
Because of this Mirroring feature, your two HDDs/SSDs will keep an identical data
after your wtiting works. In case one of the two HDDs/SSDs is defect, ST2-B31+
would still work ne with only one of them. And once inserting a good HDD/SSD as
the defect replacement, it will do the rebuilding work by itself.
With JBOD mode, you could actually use the two HDDs/SSDs as the normal two
storages for your large memory capacity requirement, but no data porotection
feature.
You could enjoy a double memory capacity from this BIG feature, but no data
porotection feature.

The Standard Procedure to Switch RAID Setting
Step-1: Please rst connect ST2-B31+ to your Mac with Thunderbolt cable..
Step-2: Please set RAID Dip Switch to the position you choose.
Step-3: Please use the Key to press the hidden RESET key at the back-plate, hold and wait for
the end of Blue-Purple LED blinking till a stable Blue light.
Step-4: Please turn o󰀨 your ST2-B31+, and re-turn it on again. You now have reset ST2-B31+
with a new RAID mode successfully.

3. 硬體需求與注意事項
1. 硬碟格式化後，由電腦主機作業系統所辨識 ST2-B31+ 的實際總容量會與硬碟廠所標示的容量加總
後，將有所差異。
2. 當系統運作時，請勿任意移除，以免導致資料遺失。
3. 為了確保節能功能的正常運作，請將 USB 連接線常態性與電腦端保持連接。
4. 完成系統初始化安裝後，在使用上請勿任意變更硬碟位置；此動作將可能導致系統無法形成
RAID。
5. RAID 模式一旦設定完成，若要進行切換，因切換過程中將會清除硬碟中的資料，請務必先將硬碟
中的資料另行備份後再行切換。
6. 在新增或變更 RAID 模式後需重新啟動產品，以確保完成更新為新的 RAID 模式。
7. 當支援 USB PD 功能的 Notebook 僅連接 ST2-B31+ 時，ST2-B31+ 可以提供最多 24W (12V/2A)
的電源供應，但後續再接上原本 Notebook 的電源供應器時，主要供電來源將由 Notebook 自行判
斷，以可供應較大瓦數的電源為主，此時的 ST2-B31+ 有可能會因此中斷供電並重新被 Notebook
辨識，因此當要接上其它電源時，請務必先確認當下 ST2-B31+ 並沒有資料存取的動作。
8. ST2-B31+ 的PD 功能，最多僅能提供 24W ，主要在延長 Notebook 的使用時間，與原本
Notebook 電源供應器的瓦數有落差，以 Macbook Pro 13" 為例，電源供應器為 60W，假設使用原
本的電源供應器充飽電需要 2 小時，透過 ST2-B31+ 大約會需要 3 倍的時間。因此如果需要長時
間使用 Notebook ，建議先接上 Notebook 原本的電源供應器後再接上 ST2-B31+。
9. 當您需要關閉或移除 ST2-B31+ 時，務必透過您所操作的作業系統中執行硬碟安全移除後，方進行
電源關閉的動作。
10.強烈建議除了使用 ST2-B31+ 的資料儲存功能外，請針對重要資料備份到另一個儲存裝置上或遠端
備份，雙重備份您重要的資料。若您儲存在 ST2-B31+ 的資料損毀或遺失，STARDOM 將不負任
何的責任。

5. RAID 模式切換設定
RAID 0：一個大的獨立資料儲存容量，並可加速資料存取但無資料保護功能。
RAID 1：兩顆硬碟是鏡射關係因此擁有相同的資料，因此有一顆硬碟損毀仍然可以正常運作。
當放⼊入新硬碟取代損毀硬碟後，系統會自自動將資料重建到新的硬碟。
JBOD ：可對兩顆獨立硬碟進行管理的工作，能大幅增加硬碟管理上的便利性，但無資料保護
功能。
BIG ：兩顆硬碟的容量會被加總成一個大儲存容量，但無資料保護功能。
（預設）
切換 RAID 設定的標準程序：
步驟 1：請在 ST2-B31+ 連線到電腦後，一併打開電腦和 ST2-B31+ 的電源開關。
步驟 2：請在藍燈恆亮時，將在 ST2-B31+ 背板上設定 RAID 設定的「切換開關」調到你所要的
設定位置。
步驟 3：請使用頂針插入「重置鍵」，待前面板抽取盒上的閃爍藍紫燈結束、並轉成恆亮藍燈後
鬆開頂針。
步驟 4：請您再做一次關、開 ST2-B31+ 電源的動作後，您已經改變、並重新設定了 ST2-B31+
的RAID。

9. 更換硬碟與資料重建說明
1. 使用 ST2-B31+ 過程當中 ,如硬碟故障而必須更換新硬碟時，請參考「章節 4_ 硬體安裝」，取出
故障硬碟並更換成新硬碟。故障硬碟一旦完成更新並開機後，ST2-B31+ 會自動進行資料重建功能。
2. 在資料重建的過程當中，如其中硬碟又再次發生故障，而導致資料重建無法繼續。請將 ST2-B31+
重新開機，再次確認硬碟是否故障，如果確定有故障，請參考「章節 4_ 硬體安裝」進行硬碟更換。
注意：
ST2-B31+ 容許資料重建過程中斷。如您在資料重建過程中將電源關閉，在您下次開機，過程將會從
您上次關機時的階段繼續進行直到完成。請勿任意改變硬碟的位置與順序。
1. USB Power Delivery ( 簡稱 USB-PD )，為 USB 開發者論壇（USB-IF）推出快速充電技術與統一連
接線標準。 ST2-B31+ 支援 USB-PD ，若採用 USB Type-C to USB Type-C 介面，可提供 5V/3A
(15W), 9V/2A (18W), 12V/2A (24W) 電力給主機端。
2. 若所連接之主機端為支援 USB-PD(5V/9V/12V) 充電的筆記型電腦，在 ST2-B31+ 開機的狀態下，
將筆電關機或重新開機後， USB-PD 仍會維持充電功能。
