Figure 5-4: Sun Fire X4600 Power Supply Units
Power supplies are monitored and managed by ILOM. However, PSU fans are NOT individually managed by
ILOM. Instead, they are considered part of the PSU unit. Therefore, a failure of a PSU fan is reported by ILOM as
a failure of the entire PSU unit.
The power supplies have the following features:
•850 Watts high efficiency PSUs for Sun Fire X4600
•950 Watts high efficiency PSUs for Sun Fire X4600 M2
•Hot swappable
•120/240 Volt – 50/60 Hz Autodetect
•83% efficiency for the 850 Watt PSU
•90% efficiency fro the 950 Watt PSU
•N+N redundancy
•Two cooling fans
