Power off the system.

1. 

Remove any USB memory devices connected to the system. The  uninterruptible power supply (UPS) can remain connected.

2. 

Insert  the  external  USB  flash  drive  that  contains  a 

3. 

vmlinux  file  into  the  AUX-2  port  on  the  back  of  the  failed  system.  We 

recommend you use the AUX-2 port for rebooting the NAS so that the USB port on the front panel can be used for saving your 

configuration. 

 The recovery vmlinux files for NSS4000 and NSS6000 are different; make sure you have the correct file installed on the USB 

flash drive.

Power on the system. After 3-5 minutes, the power LED flashes green, indicating that the system has booted from the external 

4. 

recovery USB flash drive. As soon as the power LED flashes green, remove the external USB flash drive.

 If you do not remove the external USB flash drive within 10 seconds after the power LED flashes green, the system fails to boot. 

Return to Step 1.

Let the system boot fully (indicated by the power LED displaying steady green and the System LED turned off). This takes an 

5. 

additional 3 to 4 minutes. 
Insert the recovery USB 2.0 flash drive into the AUX-2 port again. 

6. 

 Leave the external USB flash drive permanently inserted in the unit.

Before performing the firmware upgrade, make sure the recovery USB flash drive is inserted into either the USB port on the front 

panel or AUX-2 port on the back of the NAS.

  If the recovery USB flash drive is not inserted into either the USB or AUX-2 port, the system will fail to automatically 

boot after you perform Step 5.

The firmware upgrade takes about 13 minutes. To upgrade the firmware:
