Electrical Requirements
This section provides information regarding site power and wiring, AC power
requirements, and power cord routing instructions.
Site Wiring and Power
The 6540 tray uses wide-ranging redundant power supplies that automatically
accommodate for voltages from the AC power source. The power supplies operate
within the range of 90 VAC to 264 VAC, at 50 Hz to 60 Hz. The power supplies meet
standard voltage requirements for both domestic (inside USA) and international
(outside USA) operation. They use standard industrial wiring with line-to-neutral or
line-to-line power connections.
Power Cords and Receptacles
Two AC power cords (IEC C13 to C15) are used to plug into the customer-supplied
power distribution unit (PDU).
Each power cord connects one of the power supplies in a tray to an independent
external power source, such as a power strip as provided in a Sun cabinet or an
outlet from a power distribution unit.
Power Input
The AC power sources must provide the correct voltage, current, and frequency
specified on the tray’s model and serial number label. The tray can run without
interruption within the limits shown in
