During device upgrade one of the following messages appears: “UNKNOWN ERROR Current image
version” or “UNKNOWN ERROR”.
Probable Cause Corrective Action
A communication error
between the devices and the
server.
 If this failure occurred after clicking Update All
Devices, power cycle each device that did not
get upgraded. Unplug the power cord and plug it
back in. As each device restarts, it automatically
updates (if it detects updated software in the
system).
 Wait 30 minutes to allow for the device to
update. If the system has a very low bandwidth
Internet connection, it may take up to 4 hours.
 If this failure occurred during a manual
single-device update, power cycle the device that
did not get upgraded. Unplug the power cord and
plug it back in. As the device restarts, it
automatically updates (if it detects updated
software in the system).
