Dell Force10 C150 Installing and Maintaining the C150 System - Page 51

A Alarms The C150 system generates alarms for the following conditions: • fan tray status • power supply status • RPMs status • high temperature on RPMs • line cards status • high temperature on line cards A major alarm is any fault that would render the C150 system non-functional. A minor alarm is any fault that threatens the operation of the C150 system. You can monitor alarm conditions on the C150 system through the console and LEDs. If you configure the SNMP command snmp-server enable traps envmon, FTOS also sends an SNMP trap. In the C150 system, alarms are logged for each occurrence, but the system may not send an event log for multiple occurrences. For example, whenever a module exceeds the shutdown threshold, the module shuts down. If more than one module exceeds the warning or high-temperature thresholds within a five-minute period, the system generates one event for all affected modules, but alarms are logged for each occurrence. If the module temperature falls to 5° lower than the warning threshold temperature, the system clears the alarm and an SNMP trap. Table A-1.
