Getting this OID will cause the status of all outlets to be
returned. This OID is provided for informational purposes only.
To change the outlet state, the user should use the sPDUOutletCtl
OID in the sPDUOutletControlTable.
The format of the data returned is a character string consisting
of the word 'On' if the outlet is on or 'Off' if the outlet is
off. At least one space will delimit each outlet entry in the
string.
If the outlet states are unknown, the character string 'Unknown'
will be returned. This signifies that there is an inconsistency
in the PDU. In the rare case that this should happen, the user
is advised to shut down all equipment powered by the PDU and
then cycle the PDU's power. This will put the PDU in a consistent
state.
