Table 2-2 Power On/Off Button
DescriptionButton/Switch
Controls the power supply (turns system power on or off) if power is available to the power
supply. (Controls both power supplies if two are installed).
If power is off but power is available to the power supplies, pressing the Power button:
• Momentarily (less than 5 seconds) turns on the power supplies and applies power to
server circuits.
• More than 5 seconds, then released, has no effect.
If power is on and the system is at initial system loader, pressing the Power button:
• Momentarily (less than one second) has no effect.
• More than one second, but less than five seconds—do not use. This initiates e-buzzer
functions that are not supported in the server.
• More than five seconds, then released, causes an immediate hard power off.
If power is on and the system is at BCH, pressing the Power button:
• Momentarily (less than one second) causes a immediate and hard power off.
• More than one second, but less than five seconds—do not use. This initiates e-buzzer
functions that are not supported in the server.
• More than five seconds, then released, causes an immediate hard power off.
If power is on but the operating system shuts down, pressing the Power button:
• Momentarily (less than 5 seconds) causes a system power off.
• More than five seconds, then held, causes a system power off.
If the OS is running, pressing the Power button:
• Momentarily (less than 5 seconds) requests a soft power down by the operating system.
The operating system determines if the power off request is to be honored.
• More than five seconds, then released, causes an immediate hard power off without
allowing the operating system to close open files or flush disk caches possibly resulting
in a corrupted disk system or file. This should only be used when the operating system
is not responding to user requests.
