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 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 on S-Series environmental monitoring
hardware and hardware components.
Table 14. SNMP Traps and OIDs
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
.1.3.6.1.4.1.6027.3.10.1.2.5.1.7 chSysPortXfpRecvTemp OID displays the temperature of
the connected optics.
NOTE: These OIDs only
generate if you enable the
