Serial Port Snoop Setup Menu
This menu can be used to set up Serial Port Snooping, in which the user can
configure Serial Port 1 as a "catch-all" reset device.
From the Service Processor Main Menu, select option 1, Service Processor
setup menu, then select option 8 (Serial Port Snoop Setup Menu).

Use the system reset string option to enter the system reset string, which resets
the machine when it is detected on the main console on Serial Port 1.
Use the Snoop Serial Port option to select the Serial Port to Snoop.
Note: Only Serial Port 1 is supported.
After Serial Port Snooping is correctly configured, at any point after the system
unit is booted to AIX, whenever the reset string is typed on the main console, the
system unit uses the Service Processor reboot policy to restart.
Pressing Enter after the reset string is not required, so make sure that the string
is not common or trivial. A mixed-case string is recommended.
