2921.0. "Is this a valid MultiStack management config?" by ZPOVC::HWCHOY (On a foul day, you can complain forever.) Sat Oct 28 1995 15:02

Hi,
    
    I would like some advise if the following config is valid.
    
    I wish to have a single stack domain managed by a 90TS, but comprising
    two segments. They are connected back to a DECswitch 900EF with two FO
    MAU on the AUI ports. Since only the DETML-UE has an AUI connection, I
    would have to put FO MAU on these rather than putting one on the 90TS.
    
    Question is, is it necessary for the managing agent to be physically at
    the "head of management chain", or can I simply wire them physically as
    shown and set the 90TS position to 15?
    
    I prefer to use the 90TS than the 90FS because it is much cheaper while
    giving 8 ports.
    
    Thanx and rgds,
    Heng-Wah

    No, it is not necessary.  The management chain will work just fine no
    matter how it is physically wired.
2921.2DETAX/AUI and 90T-16 Thinwire active simultaneously?ZPOVC::HWCHOYOn a foul day, you can complain forever.Mon Oct 30 1995 12:038
    Another matter that was bugging me:
    
    If I run the 10BaseFL to a DECrepeater 900T-16/DETAX's AUI port (via FO
    MAU) the Thinwire would still be active, and can be used to chain up
    other modules. I'm under the impression that the 90TS's AUI and
    Thinwire is mutually exclusive so I thought I should just ask.
    
    thanx,hw

    Your impression about the 90TS's AUI and Thinwire ports being mutually
    exclusive is correct.  One or the other can be active at any given
    time, but not both.
    
    The 90T-16/DETAX's AUI port is always available... even when the
    Thinwire is being used as well.
2921.4Thanx, maybe we can rename it the 90T16+2 :)ZPOVC::HWCHOYOn a foul day, you can complain forever.Tue Oct 31 1995 06:381
