D-Link DSR-Series User Manual 183
Section 9 - Maintenance
You can upgrade to a newer rmware version from the Administration web page. In the Firmware Upgrade 
section, to upgrade your rmware, click Browse, locate and select the rmware image on your host, and click 
Upgrade.  After  the  new  rmware  image is validated,  the  new image is written  to ash  and the  router will 
automatically reboot with the new rmware. 
Warning: During the rmware upgrade, do NOT try to go online, turn o the DSR, shut down your PC, or interrupt the 
process in anyway until the operation is complete. This should take only a minute or so including the reboot process. 
Interrupting the upgrade process at specic points when the ash is being written to may corrupt the ash memory 
and render the router unusable without a low-level process of restoring the ash rmware (not through the web GUI).
