| Example 1 (redundant distribution panel and switch gear)
In this example, the computer receives power from four separate power distribution panels. The four
|
distribution panels receive power from two pieces of building switch gear.
|
| This type of power distribution will not result in system outage in the event of a power failure at either
| switch gear or one of the distribution panels. IBM recommends this power distribution to achieve highest
availability.
