Troubleshoot an Over-Temperature Condition

To troubleshoot an over-temperature condition, use the following commands.
1. To monitor the temperature levels, use the show environment commands.
2. Check air flow through the system. Ensure 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, Dell Networking requires that you install blanks in all slots without a line card to control
airflow for adequate system cooling.
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 declares an alarm.
To recognize this condition, look for the system messages shown in the following example.
%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 route processor modules (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 LEDs are lit.
The simple network management protocol (SNMP) traps and object identifiers (OIDs) shown in the
following table provide information on environmental monitoring hardware and hardware components.
