A-Class Server Fault Condition Recognition
Overview
The existence of fault conditions are determined by reviewing Front Panel LED Status
codes (shown below), or reviewing Review Console Messages.
The following subsections describe fault condition review procedures.
Review Front Panel Status LEDs
Front panel LEDs display either normal operation or fault status of the A-Class server.
Fault conditions consist of selftest failures and High Priority Machine Check (HPMC)
fault conditions. The following table describes what the front panel LED blink patterns
indicate:
