Power error messages Note: See "System replaceable units" on page 131 to determine which components should be replaced by a field service technician. Message Action Power supply x current share fault (level-critical; excessive current demand on power supply x) v Replace power supply x. Power supply x DC good fault v Replace power supply x. (level-critical; power good signal not detected for power supply x) Power supply x temperature fault v Replace power supply x. Power supply x removed v No action required - information only. Power supply x fan fault (level-critical; fan v Replace power supply x. fault in power supply x) Power supply x 12 V fault (level-critical; overcurrent condition detected) v See "Power checkout" on page 21. Power supply x 3.3 V fault (level-critical; 3.3 V power supply x had an error) v See "Power checkout" on page 21. Power supply x 5 V fault (level-critical; 5 V v See "Power checkout" on page 21. 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 system. 3. System can continue to operate without redundancy protection if steps1 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, if installed. System shutdown See the following tables when experiencing system shutdown related to voltage or temperature problems. Voltage-related system shutdown Note: See "System replaceable units" on page 131 to determine which components should be replaced by a field service technician. Message Action System shutoff due to x current over max value (level-critical; system drawing too much current on voltage x bus) v See "Power checkout" on page 21. System shutoff due to x V over voltage (level-critical; system shutoff due to x supply over voltage) 1. Check the power-supply connectors. 2. Power supply. 3. Power cage assembly, if installed. 124 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide
