DC Power Distribution
Sun Fire platform DC power is organized into power grids, each grid
supporting specific system board slots.
F3800, F4800, and F4810 platforms support a single power
grid:
grid 0
.
The F6800 platform supports two power grids:
grid 0 & grid 1
Note –
When creating domains on a Sun Fire 6800, do so within power
grids if at all possible. This will give the best availability.
The Sun Fire platforms offer hot-swappable and redundant (N+1) power
supplies.
Power supplies are interchangeable among the F6800 and F4810
platforms. The F4800 platform has a different style of power supply. The
SunFire 3800 platform has still another style of power supply.
