3421.0. "DETMR - DEChub1 - thinwire tab still to be used?" by BACHUS::KNEUTS (Erwin Kneuts DTN 856-8726) Wed Apr 03 1996 12:40

Hello,


On a DETMR (repeater 90-T) one can use 
when standalone: 8 UTP ports + 1 thinwire
when in hub90/900:   8 UTP ports + backplane to thin/thick	
                     thin tab on DETMR can not be used. (only due to physical
                     constraint??)

My customer has his DETMR sitting in a DEChub 1, and uses
8 UTP ports + thinwire on DETMR + AUI Through dechub1 backplane.

To my surprise this works fine.  When I apply analogy of DEChub90/900, this is
not a supported config. 

Can one comment on this please.

thx

3421.1DEChub1 is in fact a multi stack block.BACHUS::KNEUTSErwin Kneuts DTN 856-8726Wed Apr 03 1996 12:514
Hello,

Just found out that DEChub1 in base note is in fact a 1 element multistack.
Does this change the picture?

    Funny, from all we have been hearing, the AUI port on the multistack 
    unit (DETAX) ONLY works with the 16 port repeater (DETML)!
    
    The DETMR, when inside a HUB90/900, gets its thinwire port re-directed
    to the backplane, hence becomes un-available, even if you could get at
    it physically, like when there is no module next to it.

3421.3there's always a logical down to earth explanation for "miracles"BACHUS::KNEUTSErwin Kneuts DTN 856-8726Thu Apr 04 1996 11:2415
Hello,

The "miracle" is solved.
2 different problems/configs were mixed up.

1) Working config
The DETAX  + 16 port repeater : AUI on DETAX + thin + UTP connected.
Works fine and this is expected to work fine

2) Bad config
DETAX + 8 port repeater.:  repeater does not init correctly.
Expected behaviour. not supported.

cheers
