Upgrade
When newer versions of NR300 firmware become available, the user can manually update the
unit by uploading a package to the unit.
NOTE:
The unit need manually reboots once the upload completes, thus taking the NR300 router
out of service during approximately 1 minute. Unless otherwise stated, the user is not expected to
take any special precautions.
CAUTION:
It is important to have a stable power source and ensure that power to the Fusion is not
interrupted during a firmware upgrade.
