Power supplies
The two power supplies mount in the rear of the enclosure (see
). The supplies are autoranging
and operate on a country-specific AC input voltage of 202 to 240 VAC ±10%, 50 to 60 Hz, ±5%, (188
to 264 VAC, 47 to 63 Hz).
The DC outputs of this power supply are:
•
+5.1 VDC for the EMU, I/O module,
, and disk drives
•
+12.1 VDC for the disk drives
•
+12.5 VDC for the disk drives
The output of each power supply is 499 W, with a peak output of 681 W. A single power supply can
support an enclosure with a full complement of disks.
The power supply circuitry provides protection against:
•
Overloads
•
Short circuits
•
Overheating
Power supply status and diagnostic information is reported to the EMU with voltage, current, and
temperature signals.
See
Regulatory Notices and Specifications
for the enclosure power specifications.
The power supply temperature sensor provides a temperature range signal to the EMU, which uses this
signal to set the
speed.
The power supply internal temperature can also control the speed of the blower. The higher the power
supply temperature, the faster the speed of the blower. If the power supply temperature exceeds a preset
value, the power supply automatically shuts down.
