3142.0. "Power Redundancy in MultiStack ?" by DIAS::SYSTEM () Wed Jan 10 1996 02:38

    Hello out there,
    
    		I have a question regarding multistack power supplies.
    Do we have redundency in the case of a power supply failure in the
    stack, if we have a power supply failure. If so how is it achieved 
    or configured.
    
    Regards....

	the Multistack does NOT provide redundant power capabilities.
3142.2	But when you hear the answer it sure hurts..	DIAS::SYSTEM		`Wed Jan 10 1996 08:55`	5

	But since each StackStation has its own independent supply, a power supply problem is more isolated (as opposed to say, losing an entire hub...) no? -Mike

	Mike, Yes, I agree. It's a better solution that say a DEChub 90. When all the DEChub 90-style product groups make a stackable (-SA) variant, I would choose this over a DEChub 90 anyday. Yes, multiple independent power supplies are much better than a DEChub 90 but less than an n+1 DEChub 900.
