Troubleshoot an Over-temperature Condition
To troubleshoot an over-temperature condition, use the following information.
1
Use the
show environment
commands to monitor the temperature levels.
2
Check air flow through the system. Ensure that the air ducts are clean and that all fans are working correctly.
3
After the software has determined that the temperature levels are within normal limits, you can re-power the card safely. To bring
back the line card online, use the
power-on
command in EXEC mode.
In addition, to control airflow for adequate system cooling, Dell Networking requires that you install blanks in all slots without a line card.
NOTE:
Exercise care when removing a card; if it has exceeded the major or shutdown thresholds, the card could be hot to the
touch.
Recognize an Under-Voltage Condition
If the system detects an under-voltage condition, it sends an alarm.
To recognize this condition, look for the following system message:
%CHMGR-1-CARD_SHUTDOWN: Major alarm: stack unit 2
down - auto-shutdown due to under voltage
.
This message indicates that the specified card is not receiving enough power. In response, the system first shuts down Power over
Ethernet (PoE). If the under-voltage condition persists, line cards are shut down, then the RPMs.
Troubleshoot an Under-Voltage Condition
To troubleshoot an under-voltage condition, check that the correct number of power supplies are installed and their Status light emitting
diodes (LEDs) are lit.
