3373.0. "*** CAUTION *** DEChub ONE "rev. # A01"" by FOUNDR::SKABO (Expect Nothing U never disappointed) Mon Mar 18 1996 15:03

                           DEChub ONE "rev. # A01"

	We just received in January 1996 - 10 DEHUA "rev. # A01" power 
supplies for use with DECswitch 900EF modules now we have to order the newer 
"rev. # A02" power supplies or the DEChub ONE-MX supply. !@#$%^&*()

	If you have a DEChub ONE (DEHUA) "rev. # A01", this will not have 
enough power to bring up a DECswitch 900EF (DEFBA) module. You "MUST" have the 
DEChub ONE (DEHUA) "rev. # A02" for the DEFBA to come up. The DECswitch 900EF
requires 45 Watts @ V5.0 and the DEChub ONE (DEHUA) "rev. # A01" only supplies
40 Watts @ V5.0 

	Why are they still shipping "older" rev. DEChub ONE power supplies????

3373.1Hmmm so which ones are still shipping??NETCAD::BATTERSBYMon Mar 18 1996 15:2815
    >>                                                    The DECswitch 900EF 
    >>requires 45 Watts @ V5.0 and the DEChub ONE (DEHUA) "rev. # A01" only
    >>supplies 40 Watts @ V5.0
    
    My recollection of this is that the original DEChub ONE (DEHUA)
    could only supply 45 watts (I'm sitting here staring at the label
    of one as I type this). The newer replacement DEChub ONE (DEHUA) can
    supply 90 watts (I'm staring at one of these too).
    Now, the DECswitch 900EF requires 67.5 watts, not 45 watts.
    Notwithstanding the wattage differences, you are correct in your
    basic premise that the older DEChub One (45 watt versions) should
    not be used with the DECswitch 900EF.
    I thought that they had discontinued the older one also.

    This might help.

     -DEHUA-NB is a 90W power supply. DEHUA-NB rev A01 or A02 (or any rev)
      are 90W, so you could use either rev with DECswitch 900EF.
    
     -DEChub ONE-MX is DEF1H-MB, which is a 90W power supplies with two
      MODPMD ports, and supports the DECswitch requirments as well.
    
     -DEHUA-MB is a 45W supply, and not to be used with DECSwitch 900EF 
      regardless of the revision.

3373.3Question on ordering process...NETCAD::BATTERSBYMon Mar 18 1996 16:407
    Majid, the DEHUA-MB appears on the std price list as a spare.
    Does this mean it can still be mistakenly ordered, or is there
    the possibility that there is a hole in the ordering/config
    system that would allow a combination such as a DEHUA-MB and 
    DEFBA-MA to appear un-checked on an order and be processed?

3373.4A catalog/customer issuePTOJJD::DANZAKPittsburgher �Tue Mar 19 1996 00:297
    Welcome - kids - to the world of customer issues.
    
    The older vershould shoul be purged/killed/deleted/etc. before it nukes
    others with out-of-date catalogues.

3373.5It's being investigated.....NETCAD::BATTERSBYTue Mar 19 1996 10:0916
    This issue is being followed up and investigated by Vern Hines.
    I suspect the only reason that the DEHUA-MB appears on the 
    standard price list is so it can replace a broken one in the field.
    However, IMHO, it would make more sense to kill the 45 watt DEHUA-MB,
    and when 45 watt DEHUA-MB units fail in the field, to replace them with
    DEHUA-NB (90 watt), not with the MB's. This simplifies inventory
    and mitigates the problem of the wrong one being used in the wrong
    application (JMHO).
    The problem is I also suspect, that because there is a price
    differential (the DEHUA-MB's appear cheaper), that people put the
    MB on the order without understanding the wattage differences between 
    the two docking stations, and where they can/cannot be used.
    In any case, after inquiring about this yesterday, I got a message
    this morning advising me that Vern would chase this one down.

3373.6There is always a back doorNPSS::FARTue Mar 19 1996 12:0412
        Thomas,

    	I like to know what power supply you have ordered ? DEHUA-MB or
    	DEHUA-NB or DEF1H-MX and from what stock room? 

    Bob,
    	A customer can not order a DEHUA-MB. There could be some in 
    	stock room 17 field spare, for customer who need replacement.
    	Thomas is in NIO manufacturing site, purchasing at the site could
    	have gone through a non external customer ordering process.
