Redundant (n+4) Power Supply
Configurations
This power configuration provides more power redundancy than the
standard configuration. AC power distribution is provided over both
power buses (A and B, C
ALLOUTS
1 and 2, respectively) as shown in
Figure 6–6. Each bus has four power supplies for a total of eight.
Figure 6–6
