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 specied card is not receiving enough power. In response, the system rst 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.

OID String OID Name Description
Receiving Power
.1.3.6.1.4.1.6027.3.10.1.2.5.1.6 chSysPortXfpRecvPower OID displays the receiving power of the
connected optics.
Transmitting power
.1.3.6.1.4.1.6027.3.10.1.2.5.1.8 chSysPortXfpTxPower OID displays the transmitting power of the
connected optics.
Temperature
