Subject: Adding a 'chasEnvironSlotIndex' to the chasEnvironTable.


Hi,

The chassis environment group contains the following objects:

               ChasEnvironEntry ::=
                   SEQUENCE {
                       chasEnvironIndex
                           INTEGER,
                       chasEnvironSensor
                           AutonomousType,
                       chasEnvironStatus
                           INTEGER,
                       chasEnvironWarnings
                           Counter,
                       chasEnvironFailures
                           Counter
                   }

These objects are fine for 'chassis wide' sensors, like a sensor which 
represents the temperature of the chassis.  But what of cases where there 
are sensors within each module occupying a slot?  For example, what if 
there were a temperature sensor on each module?  What each module had 
built-in fans which were monitored using a 'sensorFans'?

A new object could be added to this table to solve this problem.
'chasEnvironSlotIndex' could be added to represent the slot in which the 
sensor resides.  The ChasEnvironTable would then be indexed using both 
chasEnvironIndex and chasEnvironSlotIndex.  chasEnvironSlotIndex could be 
zero for 'chassis wide' sensors.

Thoughts?
