ACTIVE LEVEL field
The ACTIVE LEVEL field (see table 403) specifies the relative active power consumption level, in any.
If the application client specifies an unsupported value for the ACTIVE LEVEL field, the device server shall terminate the MODE SELECT com-
mand with CHECK CONDITION status, with the sense key set to ILLEGALREQUEST, and the additional sense code set to INVALID FIELD IN
PARAMETER LIST.
n If the ACTIVE LEVEL field is set to a non-zero value, the POWER CONSUMPTION IDENTIFIER field is ignored.
0 If the ACTIVE LEVEL field is set to zero, the POWER CONSUMPTION IDENTIFIER field specifies the power consumption identifier from one
of the power consumption descriptors in the Power Consumption VPD page (see 5.4.16) that the device server is to use as described in
SPC-5.
If the application client specifies an ACTIVE LEVEL field set to zero and a value for the POWER CONSUMPTIONIDENTIFIER field that is not con-
tained in a power consumption descriptor in the Power Consumption VPD page, then the device server shall terminate the MODE SELECT com-
mand with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the additional sense code set to INVALID FIELD
INPARAMETER LIST.
