2826.0. "HW config resets 900EF" by NETRIX::"[email protected]" (Robert Schmoelzer) Tue Oct 03 1995 17:10

On a installation at the customers site i had some "curious" effects
with a DECswitch 900EF. I had a DEChub 900MS(SW 4.0.4) with a DEFBA-MA
(SW1.5.0) in slot 7 and one PSU(H7894-MA). If i plugged in a DECconcentrator
900MX in slot 8 the DECswitch does several resets. It took about 10 minutes
until he came up again. 

Back in the office i ordered a DEChub 900MS(with one H7894), a DEFBA and a
DEFXU. I tested several configurations and could not reproduce the resets
on "HOT PLUG" the DEFXU. But if i switch a ethernet port to the backplane and
click on apply or ok the switch resets as above. There are no problems 
switching the FDDI ports, the reset occurs only with ETHERNET ports. No other
modules are in the hub, and my notebook with Hubwatch 4.1 is connected to port
6 on the switch. The switch comes up immediately if i do a Factory reset to the
Backplane. I have tried this with V4.0.0, V4.0.2 and V4.0.4 of the MAM always
with the same effect. 

Can HUBwatch or the PSU cause these troubles since i have tested 2 backplanes,
3 DEFBAs and 2 DEFXU

regards

    Check all the modules to be sure there are no bent pins.
    
    Please dump the error log of the switch(es) and MAM(s). The switch
    error log will hopefully tell us why the switch is resetting. The
    MAM error log will tell us if there is a problem with the PSU.

    Mike,
    
    I have no upgraded to MAM 4.1.0 and DEFBA 1.5.2 but there is still the

    Robert, 
    
    I have forwarded the information to the DECswitch developers. I can't
    reproduce this problem. Can you give us a step by step cookbook to make
    the problem happen? Maybe we are missing an important bit of info. Or
    maybe there is a hardware problem somewhere.
    
    Also, what is a DEFXU?
    
    FYI, the MAM error log entry is not relevent, it is a harmless error
    msg.
    
    -Mike
2826.4DEFBA restartsVNABRW::SCHMOELZER_RThu Oct 05 1995 03:4338
    Mike,
    
    A DEFXU is the 8port FDDI Concentrator with no Mod PMDs. 
    
    To give a step by step cookbook is very simple.
    
    Unpack the hub and modules
    plug the psu(note its ONE H7894) and the module (DEFBA-MA) in
    power on
    wait until all comes up
    set IP adresses for MAM and DEFBA
    plug the notebook cable to one of the ehernet ports
    start hubwatch 4.1
    double click the DEFBA
    select one of the ethernet ports to switch back
    click apply or ok
    DEFBA resets
    
    Some other issues
    only with the newest MAM Firmware(4.1) the hub recognizes that there is
    a 163W PSU in and displays that on the LCD. The HUbwatch Message box
    gives an error on the startup "wrong PSU chas index" or similar.
    
    Today i am going to the customers site again to check if that hub works
    with my other modules. Note that i CAN switch ALL ports on the
    customers hub to the front or to the back. At that hub i have the
    problem with the DEFBA restarts when plugging in the Concentrator(maybe
    even another module, i have to check this today). 
    
    Q: Can it be an issue that there is only one PSU in the hubs, even i
    have some Watts left with two modules. Does the modules need more power
    when switching ports from the back to the front on hot swap?
    
    regards
    Robert

    Like I said, check all the pins.
    
    If this switch is crashing, we'll need the error log for it also; you may
    possibly have a hardware problem with it.

    Changing ports front/back shouldn't affect the power allocation. It
    looks like the switch crashing; not with power needs. We need to
    figure out why the switch crashes. Is there something you are observing
    with the hub behavior that makes you think it is power related? Like,
    the LCD dims, the  modules go unpowered (switch DC OK led goes out) or
    something like that?
        
    But to be sure, you might try plugging in an additional supply
    temporarily just to see what happens.
    
2826.6The resultsNETRIX::"[email protected]"Robert SchmoelzerTue Oct 10 1995 12:3711
Mike,

Just fyi here is the results for all the problems. On the customers site i
had a DECswitch 900EF wich was defective(DOA), and in the office it was the
DEChub 900MS Backplane which was defective(also DOA). So there were two 
different parts which caused the same fault. Thats bad luck.

regards 
Robert
