This value represents a bit-field of the various operational states of the PDUs that are part of the cluster of PDUs being monitored by this agent. This value is the bit-wise logical OR of all of the 'lgpPduEntrySysStatus' columns in the 'lgpPduTable' which represents the combined statuses of all PDUs for this agent. Note the bit-position is given parenthetically next to the operational state in the description below. The bit position is big-endian (least significant digit is the right-most digit). The state is present in the PDU when the bit is on (value = 1). The value is a logical OR of all of the following potential states of each PDU in the cluster. normalOperation(1) One or more PDUs in the cluster are operating normally with no active warnings or alarms. startUp(2) One or more PDUs are in the startup state (initializing). Control and monitoring operations may be inhibited or unavailable while the PDU is in this state. This state will clear automatically when the PDU(s) are fully initialized and ready to accept control and monitoring commands. unknownNoSupport(4) The state of one or more PDUs are not known at this time or there is no support for this piece of information from 1 or more PDUs in the cluster/group. normalWithWarning(8) One or more PDUs are operating normally with one or more active warnings. Appropriate personnel should investigate the warning(s) as soon as possible and take appropriate action. normalWithAlarm(16) One or more PDUs are operating normally with one or more active alarms. Appropriate personnel should investigate the alarm(s) as soon as possible and take appropriate action. abnormalOperation(32) One ore more PDUs are operating abnormally. There is a failure within the system that is unexpected under normal operating conditions. Appropriate personnel should investigate the cause as soon as possible. The normal functioning of the system is likely inhibited. unknownCommFailure(64) The state of one or more PDUs are not known due to a communications failure between the PDU hardware and the communications module. This state is usually indicative of a hardware problem.
