Yet, if a fourth AC power supply is installed, and later one of the four power supplies is removed or fails, the system generates a minor alarm and a message stating that the configuration is nonredundant (%CHMGR-1-MINOR_PS: Minor alarm: power supply non-redundant). If only three power supplies are installed and one of them fails while the E300 System is operating, the software generates a major alarm and an SNMP trap, lights the major LED, and activates the audible alarm. 58 | Alarms
