DC Power Supply Board RPWD3 Board Functions

The DC power board RPWD3 inputs - 48 V DC power and outputs - 48 V DC secondary power, and supplies power for boards on sub-rack through the backplane.

RPWD3 Board FunctionsUses 1+1 backup mode so that the power can be provided by two groups of DC powerProvides function of over current protection. When the internal current of equipment is over the current rating, power supply board will cut off the internal power supply for equipment.Provides over-voltage and under-voltage detection. When the external supply voltage is too low, under-voltage alarm occurs.When the external supply voltage is too high, over-voltage alarm occurs.Avoids reverse connection of power input endSupports hot plugging function for boards

Fan Board RFAN3

Board Functions The fan board RFAN3 is the core of ZXCTN 6300 fan rack.

RFAN3 Board FunctionsIn the left side of the case (see from the front), some fans inhale the air from the internal. In the right side of the case, it is an air inlet. This forms an air duct from the right to the left.The cold flows inhaled by the fans exchange with the hot flows of the power supply board. The heating chip uses aluminum radiator to dissipate heat.Receives speed control signal from the main control clock switching board to control fun speedDetects fan alarm information and reports it to the main control clock switching boardDetects fan information and the driving pan indicator displays fan status. Any fan has faults, the panel indicator ALM (Red) is off.
