This OID controls the behavior of a Switched Rack PDU
phase when an overload condition is possible and
additional outlets are requested to be turned on.
Setting this OID to alwaysAllowTurnON (1) will always allow
the outlets on the corresponding phase to turn on.
Setting this OID to restrictOnNearOverload (2) will not allow
outlets on the corresponding phase to turn on if the
rPDULoadConfigNearOverloadThreshold OID is exceeded.
Setting this OID to restrictOnOverload (3) will not allow
outlets on the corresponding phase to turn on if the
rPDULoadConfigOverloadThreshold OID is exceeded.
Models that do not support this feature will respond to this OID
with a value of notSupported (4). Attempts to set this OID
in these models will fail.
