Power Supply
The switch has a universal power supply capable of functioning
worldwide without voltage jumpers or switches. The supply is
autoranging in terms of accommodating input voltages and line
frequencies. A semi-custom switching power supply, repackaged for
the requirements of the switch enclosure architecture, is used.
The power supply meets the requirements shown in Table A-5.
The power supply has a modular design that plugs directly into the
enclosure through the front panel, mating to an internal blind_mate
connector. It provides facilities to support a dual redundant power
supply configuration, in which the supplies are hot-swappable.
An integral on/off switch, input filter and power indicator are
provided in the power supply.
