•
Early Power Off Warnings (EPOW) and error log analysis and alert.
•
Auto-dial out. The system objective is to predict a potential component failure by taking preventive
maintenance measures to avoid an outage.
•
Integrated system monitoring enhances failure error logging, analysis, and alert.
•
The system can be programmed by the system administrator to re-boot in most instances after
experiencing the following conditions:
AC power restored (after a power loss)
Hardware checkstop failures
Machine check interrupt
Operating system hang or failure
1.2. PowerPC Architecture
The PowerPC Architecture™ is a derivative of the multichip POWER architecture that has been
developed specifically for single-chip processor designs. The changes incorporated into the PowerPC
architecture from the POWER architecture are:
•
Simplified Instruction Set
•
Single precision floating point
•
Modified storage model
•
Multi-processor support
•
Simplified I/O architecture
The PowerPC architecture is binary compatible with applications written for the POWER architecture.
Any unimplemented, infrequently used POWER instructions are trapped and emulated.
