v Fast/Slow Boot (IPL) Capabilities
Using the operator-panel functions, you can select the IPL type, mode, and speed of
your boot capabilities. For more information, refer to operator panel functions 01 and
02 in "Operator Panel Function Descriptions" on page 206.
Attention: Selecting fast IPL results in several diagnostic tests being skipped.
Service Processor Call-In Security
If the service processor detects bad battery-powered storage (indicating that the battery
in the Operator Panel has failed or is disconnected), it maintains server security by
disabling the call-in capability to both serial ports.
When call-in is disabled, the system can still be powered on by using the ring-indicator
signal, but the service processor then causes the system to power down, preventing
access to any system facilities or AIX.
Once battery power is restored, the password(s) must be reset and the call-in
function(s) enabled. Both of these operations can be performed from the service
processor menus. See "Service Processor Setup Menu" on page 65 and "Serial Port
Selection Menu" on page 75.
