Often the first thing to try in resolving anomalous behavior on a SnapServer is to reset the
server to factory defaults. See

Performing System Resets Without Network Access

Should access to the server be lost, the Reset button can be used to reset server settings and
reestablish connectivity.
On the SnapServer DX1, the Reset button is accessed via a small hole next to the Power
button on the front of the server. Verify that the server is fully booted (as indicated by the
Status LED). Using the end of a straighten paperclip or the fine point of a instrument, press
in and hold the Reset button for a few seconds.
The system will reboot after about a minute. As a part of the reset and reboot process, the
SnapServer does the following:
• Clears user-defined settings such as DHCP configuration.
• Resets the server name to its default setting (
• Resets network speed and bonding settings to their defaults.
• Resets the Administrator password to the default (
• Resets the web server to allow http access.

Maintenance Mode

The SnapServer may enter Maintenance Mode (status LED blinking amber and green)
when GuardianOS has been compromised and is in need of repair or reinstallation. The two
functions available in Maintenance Mode should only be used under the direction of
Overland Technical Support:
• Repair – Reapplies the GuardianOSImage
• Fresh install – Reinstalls GuardianOS, overwriting any previous configurations and
destroying all disk partitions.
of GuardianOS. Failure to follow this guideline can result in total failure of the SnapServer to
start, even into Maintenance Mode. The Fresh install option should only be performed with
the same version of GuardianOS currently installed on the SnapServer, and only under the
direction of Overland Technical Support.
