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.
