hpnicfSysImageIndex 1.3.6.1.4.1.11.2.14.11.15.2.3.1.4.2.1.1

There are two parts for the index depicted as follows: 31 15 0 +++++++++++++++++++++++++++++++++++ + physical index + image index + +++++++++++++++++++++++++++++++++++ From bit0 to bit15 (two bytes) is the image index;Image file Index is a monotonically increasing integer for the sole purpose of indexing events. When it reaches the maximum value, an extremely unlikely event, the agent wraps the value back to 1 and may flush existing entries. From bit16 to bit31 (two bytes) is the physical index the same as the entPhysicalIndex specified in ENTITY-MIB. If ENTITY-MIB is not supported,the value for this object is the unit ID for XRN devices ,0 for non-XRN device which has only one main board,the board number for non-XRN device which have several main boards. Any index beyond the above range will not be supported. If a file is added in, its hpnicfSysImageIndex will be the maximum image index plus one. If the image file is removed, renamed, or moved from one place to another, its hpnicfSysImageIndex is not reallocated. If the image file's content is replaced, its hpnicfSysImageIndex will not change.
