Temperature related system shutdown Note: See "System" on page 162 to determine which components should be replaced by a field service technician. Message Action System shutoff due to board over temperature (level-critical; board is over temperature) 1. Ensure that the system is being properly cooled; see "System reliability considerations" on page 45″. 2. Replace board. System shutoff due to CPU x over temperature (level-critical; CPU x is over temperature) 1. Ensure that the system is being properly cooled; see "System reliability considerations" on page 45. 2. Replace CPU x. System shutoff due to CPU x under temperature (level-critical; CPU x is under temperature) v Ambient temperature must be within normal operating specifications; see "Features and specifications" on page 3. System shutoff due to DASD temperature (sensor x) (level-critical; DASD area reported temperature outside recommended operating range) v Ensure that the system is being properly cooled; see "System reliability considerations" on page 45. System shutoff due to high ambient temperature (level-critical; high ambient temperature) v Ambient temperature must be within normal operating specifications; see "Features and specifications" on page 3. System shutoff due to system board under temperature (level-critical; system board is under temperature) v Ambient temperature must be within normal operating specifications; see "Features and specifications" on page 3. DASD checkout Note: See "System" on page 162 to determine which components should be replaced by a field service technician. Message Action Hard drive x removal detected (level-critical; hard drive x has been removed) v Information only, take action as appropriate. Host built-in self test (BIST) Note: See "System" on page 162 to determine which components should be replaced by a field service technician. Message Action Host fail (level-informational; built-in self-test for the host failed) 1. Reseat the microprocessor. 2. Reseat the VRM. 3. Replace the microprocessor CPU. 156 xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
