3. After the software has determined that the temperature levels are within normal limits, you can repower 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.

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). 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, which provide information about environmental monitoring hardware and hardware components. Table 29.
