205.0. "FL Bridges and Repeaters Questions" by ANGLIN::ORTHOBER () Mon Apr 19 1993 15:36

	HI ALL:

	I am having a problem at a customer's site.  They have
	90FL Bridges and 90FL Repeaters.  A couple of strange things
	are happening.

	1) When I move the 90FL Repeater out of the 7 or 8 slot, it
	does not work anymore.  I see no restriction any place
	on this.  Any cluse?

	2) I have loaded the wgb31.exe in the 90FL Bridges.  I know
	that there is now problem with the Rgulare 90 Bridges,
	but waht about the 90FL Bridges?  Does the same code
	work in both (I can connect, show bridge, etc, but I am
	having some hub-watch problems).

thanks

Hello,

DECrepeater90FA, DECbridge90FL, DECagent90 and DECbridge90 have to installed 
in slot 7 or 8.

205.2Documentation and examples misleading?ANGLIN::ORTHOBERTue Apr 20 1993 21:5817
	Wow, the customer is not going to be
	happy when I have to inform him of this.

	It is not documented in the handbook that
	comes with the fiber repeater as far as I
	could see (I looked quickly) and examples
	in the Sales Update show the fiber repeater
	in other slots.

	So, if the customer wants to put a bridge,
	agent, and repeater, he is stuck right?
	The agent has to live in slot 7 with the
	bridge in 8 correct?

thanks

205.390 Hub Bus Master Bridges only?ANGLIN::ORTHOBERTue Apr 20 1993 21:597

	Also, does this mean that the fiber repeater is
	a "bus master".  If not then the only bus masterss
	at the present time are bridges, correct?
thanks

205.4DEChub 90 bus masters are...CGOS01::DMARLOWEdsk dsk dsk (tsk tsk tsk)Wed Apr 21 1993 15:3110
    The DECrepeater 90FA is not a bus master.  The DECbridge 90/90FL
    are presently the only bus masters.  The DECagent, in a future release
    of firmware will be able to be bus master, when plugged into the
    hub, without having a DECbridge 90 in the hub.
    
    Any module that has an AUI port needs to be in slots 7 or 8.  The
    DEChub 900, whenever it comes out 8^(  8^(, will not have that
    restriction.

205.5How about the DECrepeater 90FA if you're not using the AUI portBSS::AMBERMark Amber, CXO3 LAN Mgr. (DTN)592-4645Thu Apr 22 1993 16:4318
OK, let me see if I understand this...

in an earlier note, it was stated that slots 7 and 8 have an extra 12v
which is needed for devices with an AUI port.  (Further witnessed by the
two different power supplies that come with different table-top modules).
And this discussion points out that the Agent and the three other modules
with AUI ports must go in slots 7 or 8, not to be buss master, but because
they have an AUI port.  Also, the DECrepeater 90FL (no AUI port) is valid 
in any slot.

SO, my question is:

1) Will a DECrepeater 90FA work in any slot if you don't need to use
   the AUI port?

2) Why doesn't the H8727-AA power supply, which comes with DENMA-AA and
   has 5v and 12v not work with 90C, 90FL, 90TL, et.al. which only require
   the 5v
205.6AUI cannot be turned offEMDS::SEAVERBill Seaver, HUBwatch MktgFri May 28 1993 01:477
    1.  As far as I know 90 FA will only work in 12V slots (7&8).  there is
    no way to turn off the AUI port.  (Switches cost money and are
    unreliable)
    
    2.  Last time I asked the same question (no you are not crazy!), I was
    told the 5v in each supply is not the same.  One is 5.3v and that makes
    all the difference (seriously).
205.790FA works in other slotsBSS::AMBERMark Amber, CXO3 LAN Mgr. (DTN)592-4645Wed Jun 02 1993 19:254
I can't speak officially, but the 90FA does work in any slot as long as
you don't use the AUI port.  But, if you're only using the fiber port
(and the backplane/thinwire port) then it seems to work fine.  I have
serveral dozen working this way.
205.8I was wrong in .6EMDS::SEAVERBill Seaver, HUBwatch MktgThu Jun 03 1993 02:441
    I was wrong in .6.  Fiber will work in any port.  AUI only in 7 or 8.
