Recovering from a Firmware Upgrade Failure
Failsafe mode supports upgrade and front panel configuration only. This mode does not support normal
product functionality, just recovery. You cannot use SNP in failsafe mode.
1. To force the SNP into Failsafe mode, hold the Enter and Status buttons on the front panel and
reboot the box through the Power button to the left of the display.
2. Hold the Enter and Status buttons for three seconds while the unit powers up.
The operating mode will read "failsafe" on Configure Local Host.
3. Upgrade your firmware.
Your SNP will reboot into normal mode as part of the upgrade.
4. Use SNP web console to upgrade your firmware again using the same firmware revision and a
normal (not failsafe) upgrade procedure as described in
Once you've upgraded your firmware twice, the unit will reboot into normal mode.
Rebooting SNP
The SNP cannot be rebooted through the SNP Manager. To reboot SNP remotely, follow these steps:
1. Browse to http://<SNP IP>.
2. Click Reboot.
There is a reset button recessed on the SNP front panel. See Front Panel Controls (on page 30) for the
location and usage of this button.
To do a hard reset of the SNP you can reboot the box through the Power button to the left of the
display.
Restoring SNP Defaults
The SNP Console configuration page is accessed at http://<SNP IP>. On the SNP Console configuration
page, click Restore Defaults + Reboot to return the SNP to its default settings.
Or on the front panel, navigate to the parameter to delete the previous user setting. The control path
from the panel is System Information > System Control > Config Reset. Set it to Yes. Then reboot the
unit by selecting System Control > Reboot. Set this to Yes as well.
If restoring defaults is not enough, to return the SNP to factory defaults, boot into failsafe mode and
click the "Factory Reset" button.
