Alarms
The C7004/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 C7004/C150 system non-functional.
A minor alarm is any fault that threatens the operation of the C7004/C150 system.
You can monitor alarm conditions on the C7004/C150 system through the console and LEDs. If you
configure the SNMP command
snmp-server enable traps envmon
, Dell Networking OS also sends
an SNMP trap.
In the C7004/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.
