What is nnenvFanUnitIndex?

This index object identifies a specific row in the fan table, taking a value of 0 or 1 to distinguish between the chassis's (at most two) fan units. Because the table is indexed only by this value, it's how a management station correlates a given nnenvFanState reading with a physical fan position in the chassis. A device reporting fan index 0 in a trap lets the admin know which specific fan to check rather than guessing across the whole unit.
