1518.0. "DECserver 900 won't download" by STRWRS::KOCH_P (It never hurts to ask...) Tue Oct 04 1994 11:57

    Well, I believe I've found a weird failure of a DECserver 900TM. I have
    a hub with a DECbridge 900MX, DECconcentrator 900, DECrepeater 900 and
    a DECserver 900. It just sits there waiting to be loaded. I never see
    the MOP request on the machine which will load it. I've checked to see
    if I can dowload a DECserver by powering down a DECserver 300 on site
    and saw its download request. I plug into the hub console and see the
    download request on the hub terminal. However, I never see the download
    request to the system. All modules are out of the box and no
    configuration has been done on the DECbridge. If I remember correctly,
    MOP requests are broadcasts (can they eventually be blocked or is it
    multi-casts which can't be blocked?), so all bridge ports should see
    the request. We called the CSC and they recommended replacing the
    hardware (DECserver 900). Did they or I miss something obvious?

 1/ put a Terminal on port 1 of ds900 and see error message during the loading
 2/ under Hubwatch/Lan-interconnect options, see how is connected ths ds900
    (on which lan an with lan port),if my memory serves me , leg number 2
     if used for Load operation


  hopes that help you

1518.2Do you have connectivity?NETCAD::SLAWRENCETue Oct 04 1994 19:384
    
    I assume that all the modules are in the hub - where is the load host
    (how is it connected to the hub)?
1518.3STRWRS::KOCH_PIt never hurts to ask...Tue Oct 04 1994 20:1914
    re: .1 - I forgot to include that I had a terminal on port 1 of the
    server. It says that it's trying MOP ISO8802, MOP ETHERNET, IP ETHERNET
    for the load and then says it's backing off.
    
    Also, I don't have HUBwatch installed because I thought it should all
    all the modules would auto-connect to the Thinwire segment. So, the
    DS900TM should connect itself to the Thinwire and the DB900MX should
    also auto-connect to the Thinwire. The customer's systems are on either
    coming in via the FDDI (2 Digital 2100 systems) or via port 7 which is
    hooked to their backbone. On the DB900, I see 1-7 green lights which I
    suspect are the activity lights for the DB900 Ethernet segments and
    they show activity.
    
    Have I missed something or do you need more info?
1518.4The DECbridge is FRONT-PORT only w/out HUBwatchMSDOA::REEDJohn Reed @CBO, DTN:367-6463, KB4FFE, SouthEastTue Oct 04 1994 23:299
    The DECbridge900mx by default has NO CONNECTION TO THE BACKPLANE. 
    Only the front AUI and RJ45 ports are active.  A quick check would be
    to connect any of the DECbridge's 10BaseT ports to any of the
    DECrepeater 900TM 10BaseT ports.  This would attach the DECbridge to
    the Backplane without using HUBwatch.
    
    Good Luck.

1518.5STRWRS::KOCH_PIt never hurts to ask...Wed Oct 05 1994 10:413
    Aha! That's what I'll do. The CSC is obviously not aware of this. I'll
    have them plug in the repeater port to a free DECbridge port and
    re-test.
1518.6No default connect for bridges or concentratorsNETCAD::SLAWRENCEThu Oct 06 1994 15:575
    
    Neither the bridge nor the concentrator get connected to any backplane
    channels by default.
1518.7STRWRS::KOCH_PIt never hurts to ask...Fri Oct 07 1994 02:346
    
    I can understand the concentrator, but I think the default for the
    DECbridge 900 should be a default connection to the Thinwire. did I
    hear wrong that there are 7 Ethernets on this bridge (1 internal and 6
    external)? If so, why can't a default connection be made to the
    thinwire?
1518.86/1SLINK::HOODI'd rather be at the PenobscotFri Oct 07 1994 16:301
DECbridge 900MX, DECswitch 900EF:  6 ethernets, 1 fddi.
1518.9DS900EF port 3 has hooks to backplane thinwireNETCAD::BATTERSBYFri Oct 07 1994 17:305
    The second Ethernet port of a DS900EF (port 3), which is the 
    first of 4 UTP ports is the port that can optionally be connected
    in a HUB to the Thinwire LAN on the backplane.
