860.0. "dual redundancy power supply help" by EVTAI1::POUSSARD () Mon Mar 24 1997 09:29

	Hi,


	I would know the exact mechanism of power supply redundancy which
      exist on the MIKASA/NORITAKE family.

	The customer has 2 power supply H7290-AA and one small power 
interconnect cable.


	First test
	----------

	- with or without interconnect cable.

	If the machine is off, and we poweron only 1 power supply , the 
machine failed and power off again, saying that there is a problem on 1 power 
supply.


	Second test
	-----------

	If the machine is on, and we disconnect suddenly one of both power 
supply, then the machine stays on, independantly of the presence or not of 
the interconnect cable.



	- Are those scenarios normal ??

	- What is the exact goal of the interconnect cable, and is it 
mandatory if we want a dual redundancy power supply configuration ?

	

		Thanks for your help.
