Fan error messages Note: See "System" on page 108 to determine which components a field service technician should replace. Message Action Fan x failure (level-critical; fan x had a failure) 1. Check connections to fan x. 2. Replace fan x. Fan x fault (level-critical; fan x beyond recommended RPM range) 1. Check connections to fan x. 2. Replace fan x. Fan x outside recommended speed action Replace fan x. Power error messages Note: See "System" on page 108 to determine which components a field service technician should replace. Message Action Power supply x current share fault (level-critical; excessive current demand on power supply x) Replace power supply x. Power supply x DC good fault Replace power supply x. (level-critical; power good signal not detected for power supply x) Power supply x temperature fault Replace power supply x. Power supply x removed No action required - information only. Power supply x fan fault (level-critical; fan Replace power supply x. fault in power supply x) Power supply x 12 V fault (level-critical; overcurrent condition detected) See "Power checkout" on page 19. Power supply x 3.3 V fault (level-critical; 3.3 V power supply x had an error) See "Power checkout" on page 19. Power supply x 5 V fault (level-critical; 5 V See "Power checkout" on page 19. power supply x had an error) System running non-redundant power (level-noncritical; system does not have redundant power) 1. Add another power supply. 2. Remove options from server. 3. System can continue to operate without redundancy protection if steps 1 and 2 are not followed. System under recommended voltage for x 1. Check connections to the power subsystem. (level-warning; indicated voltage supply under nominal value; value for x can be +12, 2. Power supply. -12, or +5) 3. Power cage assembly.
