Figure 7. SmartNAVI Main window
If the SmartStor used to appear in the SmartNAVI Main window previously but is
no longer there, the SmartStor is probably locked up or frozen and requires a
hard reboot.
Caution
This action is appropriate only when there are no data transfers
or installations in progress.
Do not disconnect the power to reboot the SmartStor unless the
proper shutdown procedure does not work.
Keep the SmartNAVI Main window open during this procedure.
To hard reboot the SmartStor:
1. Press and hold the Power button for two seconds.
During a proper shutdown, the System Status LED turns RED, then goes
dark.
If the System Status LED stays the normal status color, the SmartStor is
locked up.
See Figure 8.
