Configuration manual

NOTE: Exercise care when removing a card; if it has exceeded the major or shutdown thresholds,
the card could be hot to the touch!
Recognize an Under-Voltage Condition
If the system detects an under-voltage condition, it declares an alarm.
To recognize this condition, look for the system messages shown in the following example.
%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). If the under-voltage condition persists, line cards are shut
down, then route processor modules (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 simple network management protocol (SNMP) traps and object identifiers (OIDs) shown in the
following table provide information on environmental monitoring hardware and hardware components.
Table 59. 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 to display 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 to display the transmitting
power of the connected optics.
Temperature
.1.3.6.1.4.1.6027.3.10.1.2.5.1.7 chSysPortXfpRecvTemp OID to display the Temperature
of the connected optics.
NOTE: These OIDs are only
generated if you enable the
enable optic-info-
update-interval
command.
