System Overview 1-107
Figure 1–49 shows both the front and rear of the AC input box used for GS80
systems. Single-phase AC input power is used in these systems. There are
three variants:
• The 30-48847-01 used in North America accommodates single phase 30 amp. 120V
power
• The 30-48205-04 used in Europe phase 30 amp. 220-240V power
• The 30-48205-03 used in North America and Japan accommodates single phase 30
amp 200-240V power
There is no visual difference between the variants except the power cord plugs.
The box has a main circuit breaker that protects all power to the system and
branch circuit breakers that protect power to the 48V power supplies and to
PCIs and storage devices. See the power distribution rules in Appendix A.
Two AC input boxes are needed in the largest of configurations.
A single LED, when lit, indicates the presence of AC input.
Table 1–14 shows which outlets each circuit breaker protects.
