    Known problem? It is on every concentrator900MX with the new firmware!
    
    Ronald

    Engineering has been looking at this problem since last Friday.
    
    When you say ALL 900MXs with this firmare are manifesting this problem
    could you please clarify that the 900MXs doing this have NOT had actual
    fan failures but have been operational all along? Also what ROM
    versions are the 900MXs running? Are all 900MXs at 3.0.1? 
    
    Hubwatch is 4.0.1 OSF?  Hubwatch Windows 4.0.1?
    
    

re:-1 

 Sorry i can't see your problem on My Hub900 in V4.0.0 and V3.0.0 of 900MX
 all fans are green on Hubwatch Unix/Windows.

  do you have only 900MX in docking station ?

    Jean-Yves,
    
    No in HUB900's on different site's different customers! with the latest
    firmware for the concentrator900. V3.0.1 and V4.0.2 (HUB).
    Can you tryit with V3.0.1 and V4.0.2?

    This seems to be a concentrator problem. We (systems Test) have a
    couple of concentrator's that always report fan problems. The key here
    is "IF the fan's ever had a problem" the hubwatch colors will be
    red/OSF & Yellow/DOS.
    I did some testing by pulling a fan wire off the concentrator, this in
    turn flags the MAM (lcd reports concentrator goes nofatal failure , and 
    then states FAN problem). If the module is removed and then fixed (wire
    back on fan in this case) the concentrator fans will always be seen in
    hubwatch as Red/Yellow for their respective hubwatch platforms.
    I have even put this concentrator in another HUB and the fans are
    displayed incorrectly by hubwatch. Where is hubwatch getting this info,
    well there are only 2 places. 1) MAM or 2) concentrator itself.
    maybe in the fast path code that hubwatch does. (directly to module)
    This has been formally QAR'd so stay tuned.

    re:.3
    
    The 900MXs with the new firmware have NOT had actual fan failures.
    I used  Hubwatch 4.0.1 OSF and Hubwatch Windows 4.0.1. When I looked
    at the ROM version and the fans are all green in UNIX and Windows?????
    The ROM version is HW=V2 RO=V1.2 Because I have seen this with my own
    eyes I have power down the HUB and now the problem is back again. 
    Fans are red in Digital/Unix and yellow in Windows! When the fans
    where green I was not able to zoom in the DECconcentrator? FDDI conf.
    was also gone. This is for my (digital) own HUB but the customer has
    the same probleem.

    Note: I can connect the HUB to easynet if you like? 
    
    
                                      

 re:.5

 No major changes (bug fix)
 have been introduced in 0.1 or 0.2 just manufacturing purpose, but i could try 
 it

 re. 6

 well i have tested your scenario and i can't confirm your result...

 _ Remove my 900MX from my HUB900

 _ Open the cover and disconnect one fan power cable.

 _ push again the 900mx on the Hub900

 _  From Hubwatch Windows fans appears in yellow and Red under Unix
 
 _ Remove my 900Mx and reconnect the power cable for the culprit fan.

 _ Now under Hubwatch (all platforms) Fans appears well good GREEN..
   even if restarting Hubwatch,HUB900, Power in the Room or whatever

 others ideas.....

    Tomorow I will upgrade one HUB with two concentrators and look again.
    When this HUB gives also concentrators with red fans you can look in
    it with HUBwatch because this HUB is already on Easenet. 
    I have send the customer a mail and ask if all the concentrators
    have the same problem or only one or two? I communicate only by
    internet mail with this customer (after he has first logged a call
    true normal channels) and must sometimes wait for a few days. He is
    traveling trouout hole western europa to setup HUB's and NETview.

    Speaking on the HUBwatch front there is a problem in the Windows
    version displaying the wrong colors (yellow when it should be red).
    The UNIX version is accurate.  The inconsistent sensor colors for
    Windows will be fixed in the V4.1 release.

    John,
    
    Thanks for your reply. I have upgrade a HUB900 on easynet now. First I
    upgrade the HUB900 to (HW=F,RO=V1.1.6).SW=V4.0.2 and after that I look
    to the Chassis Environmental Summary with HUBwatch for VMS,Unix and
    Windows. All fans green.
    After that I upgrade 1 Concentrator900MX (there are 2 in this HUB)
    anD looked again (HW=v2,RO=v1.2),SW=3.0.1. 
    Now the fans in this Concentrator900MX are red with VMS,Unix and
    Windows (yellow). and green voor the Concentrator900MX who is at 2.8.0
    The orther Concentrator is at Rom Version V1.0! but not upgraded yet.

    I got some more info here.
    The scenario I am seeing as reported in .6 is reproducable in 2
    concentrators out of 5 that I have in my hubs. Another thing noticed
    was if you insert a concentrator into the hub the bottom 2 fans will
    startup right away. As soon as the module OK led comes on, the top fan
    then energizes and now all 3 are "on" This may be some sort of race
    condition because the LCD does (if you have fast eyes) report fan
    failure and then states module UP.
    I thought at first I put the fan wires back on the wrong fans and thats
    why they were always complaining but I don't think thats the case.
    I'll take apart a good def6x and see if the fan sequence is any
    different.

  More infos too,

  i have downgraded a pairs of 900mx from V3.0.1 to V3.0.0 and
  the problem dissappears..


  may be introduce only with the version V3.0.1 isnt it ??


  JYP 

    (Continuing entry 2610 here)
    
    Our own hub has 4.0.2 and the status is correctly displayed with a
    900MX with 3.0.1 ...
    
    Pedro             

    I have also downgraded to v3.0.0 and the problem goes away.
    However, with upgrading this module back to the shipping version
    the problem comes back. (ie fans are flagged as red/yellow) So as I
    said in .6? (if the fans ever had a failure, it's there 4ever (Hope
    NOT)
    
    re-.12
     Also with v2.8.0 the fan scenario is the same. ie: bottom 2 fans start
    when module gets inserted and the last fan kicks on when the module is
    up/online.

 RE:-15

  do you want an IPMT case for it , i can open it if necessary ??

  

RE .12 & .15 - only 2 fans at first...

	The module only fires up the first 2 fans so as to not
	draw more than the allotted current for unidentified modules.
	After the module boots up, identifies itself to the hub
	and negociates for power, the 3rd fan fires up. This usually
	takes less than a minute.

    re -.16
    
    Already been Qar'd .....
    

re:-18

 do you think that an Qar will be treated as same priority than an IPMT ?

 JYP

    Ok You win IPMT it.......

 Sorry, but i wasn't game, with IPMT process, i'm sure that's the problem
 will be corrected rapidily....

 JYP

    
    Is DEF6X_V3_1_1.BIN ready to send for customers? If so will 
    gatekeeper.dec.com/pub/DEC/hub900/firmware then updated with this
    firmware (and other) or is that not the right procedure?
