“Power”

AC Voltage

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.

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.
