nnenvPwrsupPowerFailCount
Module: ENVIRONMENT-MIB
OID (symbolic): ENVIRONMENT-MIB::nnenvPwrsupPowerFailCount
OID (numeric): 1.3.6.1.4.1.562.73.1.1.1.3.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Number of failures of either power supply since boot-up.
What is nnenvPwrsupPowerFailCount?
This read-only counter tracks how many times either power supply has failed since the device last booted. A rising count without a corresponding reboot indicates recurring power instability, such as flaky input power, an aging supply, or a marginal connection, that an admin should investigate before a full outage occurs. Seeing nnenvPwrsupPowerFailCount jump from 0 to 3 over a week would prompt an admin to check redundant power feeds or swap the suspect supply.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.73.1.1.1.3.1.3 snmpwalk -v2c -c public <target> ENVIRONMENT-MIB::nnenvPwrsupPowerFailCount
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.562.73.1.1.1.3.1.3.1 snmpget -v2c -c public <target> ENVIRONMENT-MIB::nnenvPwrsupPowerFailCount.1
