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.
