5. การตั้งค่าและการติดตั้ง

Warning: Before proceeding with installation, ensure your computer is powered off and unplugged from the wall outlet. Always ground yourself to prevent electrostatic discharge (ESD) damage to components.

5.1 รายการตรวจสอบก่อนการติดตั้ง

• An available PCI Express slot (x1, x4, x8, or x16) in your desktop PC.
• ไขควงหัวแฉก.
• Sufficient space within your PC case for the card.

5.2 ขั้นตอนการติดตั้งทางกายภาพ

1. ปิดเครื่องและถอดปลั๊ก: ปิดคอมพิวเตอร์ของคุณอย่างสมบูรณ์และถอดสายไฟออกจากเต้าเสียบที่ผนัง
2. เคสพีซีแบบเปิด: Remove the side panel of your computer case to access the motherboard and expansion slots.
3. ค้นหาสล็อต PCIe ที่ว่างอยู่: Identify an empty PCI Express slot (x1, x4, x8, or x16). Remove the corresponding metal bracket cover from the back of the PC case.
4. ใส่การ์ด: Carefully align the gold contacts of the MZHOU USB 3.0 PCIe card with the chosen PCIe slot. Apply even, firm pressure to push the card straight down into the slot until it is fully seated. Ensure the card's bracket aligns with the opening at the back of the case.
5. รักษาความปลอดภัยของการ์ด: Use a screw to secure the card's metal bracket to the PC case. This prevents the card from moving.
6. ปิดเคสพีซี: เปลี่ยนแผงด้านข้างของเคสคอมพิวเตอร์ของคุณ
7. เชื่อมต่อพลังงานอีกครั้ง: เสียบสายไฟกลับเข้ากับเต้าเสียบที่ผนังและเปิดคอมพิวเตอร์ของคุณ

5.3 การติดตั้งไดรเวอร์

Upon booting your computer, the operating system should automatically detect the new hardware and install the necessary drivers. You can verify the installation:

• สำหรับ Windows: Open Device Manager (Right-click 'This PC' or 'My Computer' > 'Manage' > 'Device Manager'). Look under 'Universal Serial Bus controllers' for entries like 'USB 3.0 eXtensible Host Controller'. If you see a yellow exclamation mark, the driver may need manual installation or an update.
• สำหรับ Linux: ใช้คำสั่งเช่น lsusb or lspci in the terminal to check for detected USB controllers.

หมายเหตุเกี่ยวกับพลังงาน:

The MZHOU 7-Port USB 3.0 PCIe Expansion Card does not require an additional external power connector (e.g., SATA or Molex) on the card itself. It draws power directly from the PCIe slot. However, for optimal performance and to ensure stable power delivery to all connected USB devices, especially during large data transfers or when connecting multiple high-power devices, ensure your PC's internal power supply unit (PSU) is adequate for your system's total power requirements.

6. การดำเนินการ

6.1 การเชื่อมต่ออุปกรณ์ USB

Once the card is successfully installed and recognized by your operating system, you can connect your USB 3.0, USB 2.0, or USB 1.1 devices to any of the seven available USB 3.0 ports on the card. The ports are backward compatible.

6.3 การสนับสนุน UASP

The card supports UASP (USB Attached SCSI Protocol), which can significantly improve data transfer speeds for UASP-enabled storage devices, especially with small file transfers, by reducing protocol overhead and CPU utilization.

7. การบำรุงรักษา

The MZHOU 7-Port USB 3.0 PCIe Expansion Card is designed for reliable, long-term operation with minimal maintenance. Follow these general guidelines:

• รักษาความสะอาด: Periodically clean the interior of your PC case to prevent dust buildup on the card and other components. Use compressed air to gently remove dust.
• หลีกเลี่ยงความเสียหายทางกายภาพ: Handle the card carefully during installation. Once installed, avoid unnecessary physical contact or stress on the card or its connected cables.
• สภาพแวดล้อม : Ensure your PC operates in a well-ventilated area to prevent overheating, which can affect component lifespan.

8 การแก้ไขปัญหา

If you encounter issues with your MZHOU 7-Port USB 3.0 PCIe Expansion Card, refer to the following common problems and solutions:

• ไม่พบการ์ด:
  • Ensure the card is fully seated in the PCIe slot. Power off, unplug, and re-seat the card firmly.
  • ลองใช้สล็อต PCIe อื่นดู ถ้ามีให้เลือก
  • Check Device Manager (Windows) or system logs (Linux) for any error messages.
  • Ensure your motherboard's BIOS/UEFI settings are configured to enable PCIe slots.
• USB Devices Not Recognized or Malfunctioning:
  • Ensure the USB device is properly connected to the card.
  • Test the USB device on a different USB port or another computer to rule out device issues.
  • Verify that the card's drivers are correctly installed in Device Manager (no yellow exclamation marks).
  • If connecting multiple high-power devices, ensure your PC's power supply is sufficient.
• ความเร็วในการถ่ายโอนข้อมูลช้า:
  • Ensure both the connected device and the USB cable are USB 3.0 compatible. USB 2.0 devices will operate at USB 2.0 speeds.
  • Verify that UASP is enabled and supported by your operating system and storage device for optimal performance.
  • Avoid connecting the card to a PCIe slot that shares bandwidth with other high-speed components (e.g., M.2 SSDs), as this can sometimes reduce available bandwidth. Consult your motherboard manual.
• Physical Obstruction with Vertical USB Ports:
  • The USB A ports on this card are vertically oriented. If you experience difficulty plugging in USB cables due to your PC case's expansion slot design, ensure the card is securely fastened and consider the physical dimensions of your USB devices and cables.
