3.3.3 Precautions during HDD Installation

When you plug or unplug the hard disks, please take the following precautions:
1. After you have plugged the hard disk to its mounting bracket, please use the provided screws to
fix the four edges of the mounting bracket.
2. Make sure the HDD mounting bracket is steadily plugged to the chassis along the slot.
3. When you unplug the hard disk, unplug it about 3cm away from the chassis and then make it
stay about 30 seconds on the slot guide before totally unplug it from the chassis. Since the discs
of the hard disk are still spinning at high speed just after powering off, unplugging the hard disk
immediately will damage the discs.
4. The system supports disk hot swapping, yet the data storage safety is not ensured.
5. Please avoid frequent plugging/unplugging of the hard disks during the system running so as to
maintain long service life of the hard disks.
6. Take regular check and examine of the working status of the hard disks every two months, or
configure the system with auto check and examine task. Please refer to Chapter 4 for details.
