5  Upgrading router firmware  
This chapter describes how to upgrade router firmware. The upgrade process is as 
follows: 
•  Firmware is transferred to the device. 
•  Firmware is checked to ensure there are no corruptions. 
•  Firmware is saved to persistent storage. 
•  Data in persistent storage is validated. 
To avoid any unrecoverable errors during the process, you must follow several safety 
steps described in this chapter. 
On successful completion of the process, you can restart the device running the new 
firmware. 
5.1.1  Identify your software version 
To check which software version your router is running, in the top menu, browse to 
Status -> Overview.
