has failed.
• Flashing rapidly (4 times per second): The server is turned off and
is not ready to be turned on. The power-control button is disabled.
Approximately 3 minutes after the server is connected to ac power,
the power-control button becomes active.
• Flashing slowly (once per second): The server is turned off and is
