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: Line card 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.

The following table lists information for SNMP traps and OIDs on S-Series environmental monitoring

hardware and hardware components.
