Description
This article addresses what happens if a power grid fails on a Sun Fire[TM] 6800.

Steps to Follow
The Sun Fire 6800 has two power grids:

If power grid0 fails:

Domains A & B will have no power
SB0, SB2, SB4, IB6 & IB8 will have no power
RP0 and RP1 will have no power
PS0, PS1, & PS2 will have no power

If power grid1 fails:

Domains C & D will have no power
SB1, SB3, SB5, IB7 & IB9 will have no power
RP2 and RP3 will have no power
PS3, PS4, & PS5 will have no power

You can verify this by running a SC> showboards -p power

SC> showboards -p power
