Hardware Maintenance

The 4-bay Rackmount NAS has a single chassis with its own cover. Review the details below for hardware module locations and, where applicable, replacement. Refer to the product's warranty ( before performing any hardware repairs or maintenance that is not described in this manual.


  • Prior to performing most hardware maintenance, power off the product and disconnect the power from the power supply. Use the NAS OS to shut down the NAS before unplugging the power cables. If you cannot access NAS OS, push the power button or, in extreme circumstances, turn off the power source.
  • During operation, all provided hardware (including the drives in their frames) should remain in place for optimal air flow.
  • Observe all conventional ESD precautions when handling 4-bay Rackmount NAS parts. Avoid contact with backplane components and module connectors, etc.
  • The top cover should be removed only when the unit has been turned off and allowed to cool down. Potential hazards of opening the cover while the product is operating includes, but is not limited to, rotating fans and hot surfaces.

Adding/replacing a hard drive

You can replace a failed disk or expand storage space with a higher-capacity hard drive. Drives in protected RAID volumes are hot-swappable (e.g. SimplyRAID, RAID 1, RAID 5, and RAID 6). However, it is not possible to hot-swap more than one drive at a time. If you are replacing more than one drive in a volume, wait for synchronization to successfully complete before moving to the next disk.

 Important Info: Replace an existing or faulty drive with a drive of equal or greater capacity. When handling drives, make sure that they are placed (and stored) on a cushioned surface.
 Note: Seagate hard drives are optimized for use with your 4-bay Rackmount NAS. See Seagate NAS HDD for further information.
  1. Push the disk’s lock button to open the latch and remove the disk tray.

  4. Insert the new drive into the tray. Confirm that the SATA connection is at the rear of the tray.
  5. Fasten the drive to the tray using the four screws.
  6. Insert the disk into the empty NAS bay. Push the tray into the bay as far as it will go before closing the handle.
  7. If necessary, power on the NAS.
  8. Manage the new storage using NAS OS.


Removing the front cover
