In auto mode, a Pse Power Management Algorithm handles the
allocation of power to all the modules.
In manual mode, power is manually allocated to the modules
via the etsysPseSlotPowerAllocationTable.
The value of etsysPseChassisPowerAllocationAvailable is used
to determine the power available for allocation in this
chassis in both auto and manual mode.
Maintaining the value of this object across agent reboots
is REQUIRED.
