IBM RS/6000 44P manual Service Processor Call-In Security

Wait 5 minutes for the server to initialize and then call again using an ASCII terminal. The server responds by requesting a password, if set, or presenting the service processor menus. The remote user now has control of the server.

Note: For security, if the system is powered on by the remote power-on via ring indicate signal and the service processor detects an operator panel battery failure, the service processor causes the system to power off. See ªService Processor Call-In Securityº for more information.

vUnattended start mode - refer to Enable/Disable Unattended Start Mode on page 48.

The Service Processor can be enabled to recover from the loss of ac power (see Enable/Disable Unattended Power-On Mode in the SYSTEM POWER CONTROL MENU). When ac power is restored, the system returns to the then current power state at the time ac loss occurred. For example, if the system was powered-on when ac loss occurred, it reboots/restarts when power is restored. If the system was powered-off when ac loss occurred, it remains off when power is restored.

vTimed power-on - refer to the shutdown -tcommand on servers using AIX.

Working in conjunction with AIX, the Service Processor in your server can operate a timer, much like the wake-up timer on your clock radio. You can set the timer so that your server powers on at a certain time after shutting down. The timer is battery operated, so power interruptions occurring while the server is off do not affect its accuracy. Refer to the AIX shutdown -tcommand for details on setting the timer.

Note: If an ac power loss is in progress when the Timed Power-On attempt occurs, the server is not able to power on when ac power is restored.

vFollow-up to a Failed Boot Attempt

The service processor initiates a power-on sequence if a failed boot attempt is detected (due to a hardware or software failure).

vFast/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.

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 to AIX.

After 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 Service Processor menus. See ªSerial Port Selection Menuº on page 55.
