Ergonomic Information
After you have set up your system, we encourage you to visit the Healthy Computing
Web site. Good ergonomic practice is important to get the most from your
workstation and to avoid discomfort. This means that the equipment and the
workplace should be arranged to suit your individual needs and the kind of work you
do.
The Healthy Computing Web site gives ergonomic guidelines to help you understand
the ergonomic considerations that you should know when working at a computer
workstation. The address is:

Using the Service Processor and Service Director Features
The Service Processor and Service Director features protect users against
unnecessary system downtime by keeping support personnel (both internal and
external) aware of any unexpected changes in the system environment. In
combination, the two features provide a flexible solution to automated system
maintenance.
Service Processor
The Service Processor runs on its own power boundary and continually monitors
hardware attributes, the AIX operating system, and the environmental conditions
within the system. Any system failure which prevents the system from returning to
an operational state (a fully functional AIX operating system) is reported by the
Service Processor. The Service Processor is controlled by firmware and does not
require the AIX operating system to be operational to perform its tasks. If any
system failures are detected, the Service Processor can take predetermined
corrective actions. The methods of corrective actions are:
Surveillance
Call Home
AIX Operating System Monitoring
Surveillance is a function in which the Service Processor monitors the system
through heartbeat communication with the system firmware. The
heartbeat is a
periodic signal that the firmware can monitor. During system startup, the firmware
surveillance monitor is automatically enabled to check for heartbeats from the
firmware. If a heartbeat is not detected within a default period, the Service
Processor attempts to reboot the system until the system either restarts successfully,
