584.0. "battery backup?" by VAXRIO::ROLF (Vaporware Design Specialist) Mon Dec 27 1993 10:15

    The DEChub900 presentation mentions a BATTERY BACKUP. 
    
    Do we have any details yet about this function like p/n, cost, backup-
    time calculation, size, etc?

    There is some work under way on using the 48V DC plug on the bottom of
    the hub for connecting to Telco power supplies, but I havn't heard any
    status lately.  I'll forward the query to the power guy...

	Work on the battery backup solution keeps falling below other 
	activities that we consider more critical. Does anyone see 
	that we are losing business without a tried and true battery 
	backup solution? (separate discussion from dual pwr cord)

It would be a good "point of difference" to other hubs. I think it shouldn't be 
to difficult to buid one. So we don't have to spend very much money for 
engineering. We talked much about such a "could be in the future" feature 
to our customers and they realy voted it possitive.

Think that we should have eighter a battery backup, or bring the 48V port to 
work.

    In this country customers usually are worried about UPS and generally
    include them in the bids. And UPSs are expensive, compared to hubs! 
    So, if we could just simply "hook" batteries to that 48V 'port' on the 
    HUB900 backplane, that would give us a very clear advantage!
    
    Of course, that same port would also have to provide the charge path
    for those batteries.
    
    Or can we do all this ALREADY?
