1209.0. "900MX - DEChub 900 problem??" by NEWOA::HARRISON (Take the money and run!) Tue Jul 12 1994 11:41

    DEChub 900 (brand new) shipped with Hardware rev F,

    As I had ordered the DECserver 900TM without flashram I have been trying to
    downline load the server with NAS 1.3 from a node on the easynet
    without success. The server passes self-tests & points to the thinwire
    for loadhost s/w LED display indicates 4 waiting for downline load and
    eventually timesout with a 3, unable to locate loadhost. All LED's on the 
    bridge are functioning normally. I have tried an mc ncp con via sva-0 phy 
    addre, the target does not respond. As it transpires a colleague managed 
    to loan me a DECserver 90TL which normally resides on the customer systems
    LAN as detailed above. The loadhost also resides on one of the customer 
    systems and functions without problem. However when I installed the 90TL 
    in the hub and connected the Hub to backbone 1 no MOP requests are seen and
    the server fails to load! My colleague was also unable to make a conn via
    circuit phy addre to the DECbridge 900MX!! Our next task was to prove
    that the physical connection was good so we connected the transceiver
    cable that hooks onto the DECbridge 900MX onto a DECserver 200 instead.
    The server downline loaded without problem from a loadhost that resides
    on one of the customer systems. We were unable to duplicate this test with 
    a 90TL because we did not have a Thinwire - AUI Mau. I am also unable
    to try downline loading servers via the repeaters off the easynet
    because we have no UTP - AUI Mau's on site.
    
    Q 1) Can anyone comment on why the above should not work?
    Q 2) Has the hub shipped with the right level of firmware?
    Q 3) Are there any known reported bugs on the DECbridge 900MX which
    would affect the Hub from functioning normally?
    Q 4) How can I upgrade the firmware on the hub across the easynet?
    Q 5) Can anyone give me a pointer to a location for V3.0 firmware if
    it exists?
    Q 6) If the problem is I've got the wrong firmware why the hell is DEC
    shipping this out in brand new kit, and why not provide the correct
    version on diskette or tape with release notes explaining??!!!!!!!!!!
    
    In addition I have a more detailed postscript topology diagram if
    anyone would like to review it.
    
    Hope you can help.
    
    regards Al

    I have managed to successfully downline load the DECserver 900 and 90
    by using a DECbridge 90 in port 8 of the hub. So the problem directly
    relates to the DECbridge 900MX. I have tested access via the easynet
    and the customer LAN.

  al,

  Decbridge900Mx required V3.0.0 of HUBmanager (you are in V2.2.1)and
  Hubwatch V3.0 (Open-VMS VAX) to manage it.

 i think's ,you must have these pre-requis to start your installation

    See Note 1008 for location of latest shipping firmware.

    Unless configured by HUBWATCH, all ports on the DB 900 are to the
    front panel.  There is no default connection to the DEChub 900 thinwire
    segment.
    
    That's why a DB 90 works as it only connects to the thinwire and
    doesn't need HUBWATCH to tell it how to do that.
