SMC Interface J72 

The SMC interface connector is J72 on the PDU and is a 25-pin D-sub connector.  The pinout is detailed in 

Table 13

 below.  Details provided below for the 48V current monitor, 48V DC enable, and 48V DC power 

fault signals.

48V DC Enable 

The 48V DC enable is a signal from the SMC to enable the 48V DC output.  With no connections to J72, the 
48V DC output will be off.  To enable the 48V DC output, a 5V signal must be applied between pin 13 
(positive) and pin 25 (negative) on J72.  The 5V signal drives the diode side of an optocoupler to enable the 
48V DC output.  The 48V DC enable must be capable of providing a minimum current of 12mA to enable the 
power supplies.
