Appendix B - Power Supply MIB 73
© 2011 Datacom Systems Inc
An instance of an object definition using the Unsigned32 syntax type can represent an integer
value between 0 and 2^32-1 inclusive (0 to 4,294,967,295 decimal).
The object definition using the Unsigned32 syntax type follows:
in the dcomPowerSupplyStatusTable - dcomPowerSupplyIndex
The dcomPowerSupplyIndex object defines the SNMP index component associated with a
power supply.
4.1.1.2 INTEGER
There is one object defined in this MIB module using the SMIv2 INTEGER syntax type.
An instance of an object definition using the INTEGER syntax type is used to represent an integer
value as a named-number enumeration. Only named-numbers defined in the enumeration may be
present as a value.
The object definition using the INTEGER syntax type follows:
in the dcomPowerSupplyStatusTable - dcomPowerSupplyStatus
The dcomPowerSupplyStatus object defines the current state of a power supply. The named-
number enumerated values are as follow:
stateUnknown(1) - the current state is 'unknown'
stateDown(2) - the current state is 'down'
stateUp(3) - the current state is 'up'
4.2 SNMPv2-TC Textual Conventions
This section discusses Textual Conventions defined in the SNMPv2-TC [RFC2579] and used in
this MIB module.
4.2.1 TimeStamp
There is one object defined in this MIB module using the SMIv2 TimeStamp TC.
An object using the SMIv2 TimeStamp TC exposes a notion of local time relative to a local time
source. In the SNMP, the sysUpTime [RFC3418] object provides this local time source.
The value of an instance of an object using the TimeStamp TC changes when a specific event
occurs, as described in its description clause.
The SNMP managed objects using a TimeStamp TC follow:
in the dcomPowerSupplyStatusTable - dcomPowerSupplyLastChange
A change in the value of a dcomPowerSupplyLastChange instance indicates the time at which a
power supply transitioned into its current state.
A value of zero(0) indicates that a power supply was already in its current state when the
SNMP agent last re-initialized.
