(Optional) Installing a Hard Disk

(Optional) Installing a Hard Disk


Only the AR169W-P-M9, AR169RW-P-M9, and AR161EW-M1 can have a hard disk installed.


The procedures and methods for installing hard disks in different routers are the same. An AR169W-P-M9 router is used as an example here.

Tools and Accessories

  • Hard disk
  • Hard disk holder
  • M3 screws
  • Phillips screwdriver

The hard disk is not included in the installation accessory package and needs to be purchased separately.


  1. Hold down the release button on the left side of the filler panel and pull out the filler panel.

  2. Take out the hard disk holder from the accessory package, and use a Phillips screwdriver to fix the hard disk in the holder with M3 screws.


    The tightening torque for the M3 screws should be 3.5±0.5 kgf•cm. Excessive tightening torque will distort or damage the hard disk holder.

  3. Open the locking latch of the hard disk holder and insert the hard disk into the router.

  4. Close the locking latch to lock the hard disk in the router.
