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. If only three power supplies are installed and one of them fails while the E600i is operating, the software generates a major alarm and an SNMP trap, lights the major LED, and activates the audible alarm. When you operate the E600i with three AC power supplies and six or more line cards, the software lists a redundancy alarm on the console and in the show alarms command output. All line cards operate normally. SFMs and Alarms The number of SFMs present in the system when it boots determines the level of alarms sent when a fifth (redundant) SFM is removed or fails. At boot time, if five SFMs are present and functioning, the E600i system issues no alarms. However, if one SFM fails or is removed, the system send a minor alarm stating that four SFMs are present. The system requires four functioning SFMs to pass traffic. 62 | Alarms
