Note: It is also possible to enter the STAND-BY MENU from the Service Console if the
remote authorization flag is enabled. The Electronic Key can be set from the Service
Console with the same escape sequence.
The STAND-BY MENU allows the system administrator to display the physical configuration
of the system (CPUs, memory, I/O, and so on) and to set flags, such as the Fast IPL flag,
and the BUMP Console Present flag. The Fast IPL flag causes the system to skip the
second phase of the power-on tests. The BUMP Console Present flag allows the BUMP
console to be enabled or disabled during boot up. This menu also enables the service
representative to test the interconnection between the BUMP and different components
through the I2C bus or the SSbus. For instance, it is possible to send a specific string of
characters to the LCD and read the result on the Operator Panel display. Or, it is possible to
turn on the LEDs on the Operator Panel, or to turn on the power supplies and fans without
allowing the system to IPL.
