This message indicates that the specied card is not receiving enough power. In response, the system rst shuts down Power over
Ethernet (PoE). If the under-voltage condition persists, line cards are shut down, then the 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 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.

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 enable optic-

Troubleshooting Packet Loss
The show hardware stack-unit command is intended primarily to troubleshoot packet loss.
To troubleshoot packet loss, use the following commands.
•
show hardware stack-unit cpu data-plane statistics
•
show hardware stack-unit cpu party-bus statistics
•
show hardware stack-unit stack-unit-number drops unit 0-1 port port-number
•
show hardware stack-unit stack-unit-number stack-port 48-51
•
show hardware stack-unit stack-unit-number unit 0-1 {counters | details | port-stats
[detail] | register | execute-shell-cmd | ipmc-replication | table-dump}
•
show hardware {layer2| layer3} {e.g. acl |in acl} stack-unit stack-unit-number port-set
