Power Requirements
The following table describes the A/C input power specification for the Ultrastar 8.
Table 17:
AC Power Specifications
Power
Alternating Current (AC) Power Supply (2 per enclosure)
Wattage (per power supply)
Supply Rating:
80 PLUS Platinum rated
Max Power Consumption:
~2000W
Typical Power Consumption:
~1800W
Voltage (per power supply)
200 - 240 VAC, auto-ranging, 50/60 Hz
Maximum inrush current (per power
supply)
AC line inrush current shall not exceed 35A peak
measured per IPC-9592B(L) Appendix C-4.1.
Caution:
The Ultrastar 8 can only be plugged into high line (220-240 VAC). If the unit is
plugged into low line (110-127 VAC), the PSU will report a "Critical" state when status pages are
queried using SES. In this case, the enclosure will power up, but the drives will not.
* Max and typical power consumption values represent the output power to the system. Input power will vary depending
on the PSU efficiency and load sharing between PSUs.
