Recognize an Under-Voltage Condition

If the system detects an under-voltage condition, it sends an alarm. To recognize this condition, look for the
system messages in

Message 2 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
