Recognize an under-voltage condition If the system detects an under-voltage condition and declares an alarm. To recognize this condition, look for the system messages in Message 3. Message 3 Under-voltage Condition System Messages %CHMGR-1-CARD_SHUTDOWN: Major alarm: Line card 2 down - auto-shutdown due to under voltage This message in Message 3 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 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 SNMP traps and OIDs in Table 12-4 provide information on S-Series environmental monitoring hardware and hardware components. Table 12-4.
