1.13 Power Requirements
The following table describes the A/C input power specification for the Ultrastar Data60 .
Table 20: AC Power Specifications
Wattage (per power supply)
Voltage (per power supply)
Maximum inrush current (per power
Caution: The Ultrastar Data60 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. The
enclosure will remain in low-power mode.
1.14 ESD
The enclosure is designed to dissipate all electrostatic discharge (ESD) to the chassis base. Ensure that
there is sufficient electrical and mechanical connection from the chassis base to the rack rails, and that the
rack itself is tied to earth ground. Precautions must be taken to ensure that the system is not exposed to
ESD while handling components or servicing the unit.
The unit must be grounded in accordance with all local/regional and national electrical codes.

3. 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.
