A
Alarms
The C-Series System generates alarms for the following conditions:
• fan tray status
• 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 C-Series System non-functional.
A minor alarm is any fault that threatens the operation of the C-Series System.
You can monitor alarm conditions on the C-Series System system through the console and LEDs. If you
configure the SNMP command (
snmp-server enable traps envmon), the Dell Networking also sends
an SNMP trap.
In the C-Series System 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 effected modules but alarms are logged for each occurrence. If the
modules temperature falls to 5° lower than the warning threshold temperature, the system clears the alarm
and an SNMP trap.
