DESCRIPTION  
®
POWER SUPPLY 48 PIN CONNECTOR PINOUT  
The Total Access 4303 Plus DC Power Supply is a removable assembly that provides  
the voltages necessary for proper system operation. The unit features LEDs for over-  
temperature and DC output, an input fuse, and the ability to be hot-swapped when  
used with another DC supply in the same chassis. The supply interfaces to the Total  
Access backplane through a 48-pin connector. The unit accepts one or two –48 VDC  
inputs from the backplane and supplies –48 VDC fused output for use with external  
input logic, +5 VDC as hot insertion bias voltage for modules, and +2.1 VDC for back-  
plane termination. In addition, the Total Access 4303 Plus DC Supply provides alarm  
relay ouputs when installed in slot PS-A.
