LED
The green on/off LED is illuminated when the power is on.
Power Button 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
does the following:
• Momentarily (less than one second) turns on the power supplies and applies power to
server circuits.
• More than one second 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 does the following:
• Momentarily (less than one second) causes a immediate and hard power down.
• 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 OS has been shut down, 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 servers.
• More than five seconds then released causes an immediate hard power off.
If the OS is running, pressing the power button does the following:
• 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 servers.
• More than five seconds then released causes an immediate hard power off.
System LED The System LED provides information about the system status. When operation is
normal, the LED is green. When there is a system warning, the LED is flashing yellow.
When there is a system fault, the LED is flashing red.
LAN LED The LAN LED provides status information about the LAN interface. When the LAN LED
is flashing, there is activity on the LAN.
