Usually, input2  is for Bypass .

 

Each input has 3 phases.

check_snmp -H  APC_HOST1  -C public -o .1.3.6.1.4.1.318.1.1.1.9.2.3.1.3.2.1.1

SNMP OK - 0 | PowerNet-MIB::upsPhaseInputVoltage.2.1.1=0

 

the result from a UPS with bypass

check_snmp -H APC_HOST2  -C public -o .1.3.6.1.4.1.318.1.1.1.9.2.3.1.3.2.1.1

SNMP OK - 230 | PowerNet-MIB::upsPhaseInputVoltage.2.1.1=230
