Figure 2-3 RamSan Power Supply 
 
The power supply includes the following button and indicators: 
 
“Power” switch 
The large black button above the power supplies acts as an on/off switch 
and will silence the warning buzzer. 
“Power” 
AC Voltage 
•  The button provides a means to activate the power supplies (turn 
them on) after a system shutdown.  If the system shuts down for 
any reason other than a power failure, press the “Power” switch to 
turn the system back on.  If power is restored after a power failure 
or both power cords are removed and then reinserted, the system 
automatically powers on. 
•  When a power supply fails, is removed, or looses AC power, the 
power supplies beep.  If the buzzer sounds, silence it by pressing 
the “Power” switch once or by correcting the problem.  The 
silencing lasts until the problem is corrected.  Once the problem is 
corrected, the buzzer will sound again if another power failure 
occurs. 
•  In addition, the button allows the user to force a hard-shutdown of 
the system.  Only perform a hard-shutdown when you are unable 
to perform a manual shutdown and after backing up all of the data 
to external storage.  To perform a hard-shutdown, unplug or 
remove both power supply modules.  Then, hold down the “Power” 
switch for approximately 5 seconds to shutoff the batteries and 
cause the system to lose power. 
 
Warning: 
A hard-shutdown will cause data loss and should only be used when 
the user is unable to perform a manual shutdown and all the data has 
been backed up to external storage.
