Power Specifications
All products within the 9000 MPFD series use a common switching power supply.
System power attributes are shown in the table below. Power supplies are hot
pluggable and N+1 redundant.
The 9120, 9080, 9040 and 9020 systems have two independent AC inputs and one
common DC output. Each AC input supplies power to half of the power supplies.
In a 9240 system there are two independent DC outputs, which are labeled as
hemispheres (see figure A-1). The lower hemisphere is powered by the lower 6
supplies and the upper hemisphere is powered by the upper 6 supplies. There are
four independent AC inputs: two in each hemisphere. Each AC input within a
