2: System Operation and Troubleshooting
System Fan Failure
If one of the 12 fans that cool the main enclosure fails, you should be able to visually identify the
problem unit by looking through the perforated sheetmetal, see Figure 2-2. The system can run
with a single fan failure, but it should be replaced as soon as possible. The SGI Octane III Cluster
Server Component Replacement Guide has information for service personnel to replace a fan.
